Faxing - protocol selection
I am trying to understand the order of fax protocol selection. For example, lets take a PSTN gateway that is MGCP enabled. Fax passthrough, T38 relay and Cisco fax relay are enabled. Which protocol will be used to negotiate with the far end device first(ATA, vg248 etc) ? Is there a particular order in which negotiation takes place ?
On the mgcp gateway the follwing commands are present.
mgcp modem passthrough codec g711ulaw
mgcp modem passthrough voip mode nse
ccm-manager fax protocol cisco (default)
no mgcp t38 fax inhibit (default)
In my opinion the best fax protocol is T38 (standard) followed by CISCO Fax relay (similar to T38) and the last option is fax pass through.
ATA 188 doesn't support T38. You can find more info about ATA MGCP here:
http://www.cisco.com/en/US/products/hw/gatecont/ps514/products_administration_guide_chapter09186a00805fe011.html
Info about VG248 here:
http://www.cisco.com/en/US/products/hw/gatecont/ps2250/products_configuration_example09186a008020160d.shtml
On your gateway you can configure T38 as first option. If T38 negotiation fail the second option will be CISCO or pass through:
fax protocol {t38 [nse [force]] [ls-redundancy value [hs-redundancy value]] [fallback {cisco |
none | pass-through {g711ulaw | g711alaw}}]}

MGCP fax protocol incompatible with Alcatel softswitch and GWs
Hi
We are using alcatel 5020 as sosftswitch and cisco 5400,5350 and Alcatel 7515 as media gateways. But there is an incompatiblity for fax protocols. When we use T38 it can be ok but some calls get hanged on. For passthru alcatel dont uses NSE mode so no fax at all. Are there any body who encounters same issues about fax. Which one is "more" universal T38 or passthru? What are the industry standars for payload types etc?
RegardsSome of the gateways has restrictions depending upon the IOS image loaded .

I try to send several fax documents to different numbers. i have connection, then "sending" message. It stops at the end with message "hold until xxx". Any solution ?
For the longest time I used FAXstf in OS9 and all was more than beautiful. Then they sold to SmithMicro, it went to pot. So I was very happy to see Apple include FAX capability in the OS. If only it worked. It seems to be one of those peripheral applications that they include for looks not function. I have had a couple of successful FAXes go through, from the other room. But when I need it to really work it seems to just does its own thing. I set it to pick up on two rings and the phone is still ringing 6 later, but the menu bar is saying "answering . . . ". I activate it manually and it still takes longer than the sending machine will allow for a wait to pick up. I'm not real sure where the problems may lie, because I also use PageSender (Great App) that use to work flawlessly until the later OS's. So I'm beginning to think that Apple has changed something in the way the modem operates that makes it hard for this kind of software to do its job. When it works, It works great. But . . .
So I agree that it is an Apple thing that there are problems in this area. And what with them abandoning old technologies, I don't see much, if any support, or further development on this. After all, the new laptops don't come with modems anymore.
If FAXing is important, you might look into PageSender. It has many nice features that the Apple software doesn't. Like access to other address books other than Apples, FAX to eMail, and more. -
hi
i have an mpls nework with equipment cisco 2821, 2901 and 2801, and i have problems with fax calls, i configured the fax protocol t38 in all routers but when i want to send a fax to the 2821 equipment from either 2801 and 2901, the protocol t38 is not working and the fax call use cisco protocol (although t38 is configured in all routers). the calls betwen 2801 and 2901 works ok, and from 2821 to 2801/2901 works ok too.
any idea of whats happens? do you think is a problem of ios version?
these are de ios version
2821 .-c2800nm-spservicesk9-mz.124-3i.bin
2801 .- c2801-spservicesk9-mz.150-1.M6.bin
2901 .-c2900-universalk9-mz.SPA.150-1.M7.binhi
this is the configuration on the 2821:
voice service voip
fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback cisco
dial-peer voice 10037 voip

this is the configuration on 2801
voice service voip

i want to use T38 because the bandwidth of the fax call is 16K, if i use cisco protocol the bandwidth reaches up 24k, and the router start to drop voice packets

OfficeJet 4630 Defaults to Network Fax when user has selected Network Printer Instead on WIN XP
Hi, just installed the OJ4630 and selected the "Network Printer" as the default. When choosing to print an MS Word document in "My Documents" the "Network Printer" correctly appears as the default. But when choosing to print a picture in "My Pictures" the "Network Fax" becomes the default, which is an error. Please advise, thanks!
Hi
Thanks for reporting the issue. Here is the way to fix it.
Go to windows->Control panel-> Printers and devices
Right click on the 4630 Fax Printer, select the option Set as default printer and you'll see two choices there: one is printer driver and other one is fax driver. You choose print driver to set as default.
Done
Hope it will help you.
happy Printing!!!

B-channel oos and protocol error 510
Dear all,
I have some some issue couple of days ago. The telephony system of my client worked well and suddenly the cannot make external calls via E1. I checked the config and for me it seems to be ok. When I checked the SDL file, I can see the B channel out of service error message following by the
"MGCP PROTOCOL ERROR: <S1/SU1/DS1-0/[email protected]> CRCX error code: 510". They have A CUCM 6.0 and Cisco 2821 as gateway with 12.4 (25f) advance IP service IOS.
I perform the following actions without success:
-From the CUCM in the advance service I forced the Bchannel to bring it in service,
- no mgcp/mgcp, -reboot the CUCM and the Gateway,
-reset the controller throug CUCM,... in vain.
They contacted telco and has confirm that everything seems to be ok. Find below the information that can help you to undestand better

Thanks for your helpThe explanation for your syslog message is " The B-channel indicated by this alarm has gone out of service. Some of the more common reasons for a B-channel to go out of service include: Taking the channel out of service intentionally to perform maintenance on either the near- or far-end; MGCP gateway returns an error code 501 or 510 for a MGCP command sent from Cisco Unified Communications Manager (Unified CM); MGCP gateway doesn't respond to an MGCP command sent by Unified CM three times; a speed and duplex mismatch exists on the Ethernet port between Unified CM and the MGCP gateway"
Recommended action:
Check the Unified CM advanced service parameter, Change B-channel Maintenance Status to determine if the B-channel has been taken out of service intentionally; Check the Q.931 trace for PRI SERVICE message to determine whether a PSTN provider has taken the B-channel out of service; Reset the MGCP gateway; Check the speed and duplex settings on the Ethernet port. -
Fax outdial retries consume all voice channels on SIP 484 error (Cisco 2911)
I've been seeing a nasty fax/VoIP problem on a 2911, running IOS 15.0(1r)M12. Any suggestions would be welcome.
I have a 2911 which is set up to do T.37 offramp fax delivery (SMTP message is sent to 2911, which places a VoIP call over SIP/RTP/T.38 to deliver the fax). The mainline case is set up, and working correctly - faxes are delivered without issue. If a destination address is selected such that the VoIP switch returns a SIP 484 error, then everything fails in a spectacular fashion:
The outdial is immediately retried, placing another SIP INVITE to the switch, with the same destination address, which obviously also gets the same 484 response.
Each time the outdial takes place, it consumes voice channels on the DSP, which are not released on receipt of the 484.
When there are no free voice channels, a no circuit (0x22) error is returned, and all the voice channels are finally released.
The MTA that submitted the SMTP message retries every minute (it doesn't get a permanent failure report when the 2911 fails to place the call)
This leads to a situation where no fax calls can be placed, as all the voice channels are being used up by retrying this call that can never succeed.
Some other relevant information:
The VoIP switch does not return a 484 immediately. First it sends a SIP 183, and plays early media (an announcement about how the call isn't allowed).
It takes 8 seconds before the 484 is returned. The 2911 sends a new SIP INVITE every 8 seconds (as soon as it gets a 484 for the previous attempt).
The "sip-ua" statistics show that the INVITE retry counter is not being incremented (i.e. this is not a retry at the scope of the SIP stack).
The T1 cable is looped-back to the 2911, so that the complete path for fax delivery looks like this:
MTA ---SMTP---> 2911 ---T1---> 2911 ---SIP---> VoIP switch
If I set "mta receive generate permanent-error", then I still see this retry behaviour, with all the voice channels being consumed. Once that has happened (after about 3 minutes) the MTA does get the error response, and no longer retries every minute after that (although this setting has other negative effects that I'd like to avoid).
Does anyone have any idea how I can get the 2911 to return a permanent failure to the MTA after just a single outdial has failed with a SIP 484?

Why don't try to use the 2811 as a SIP signalling proxy only?
In this way the media (RTP or T.38) will be handled only from the two MERA SoftSwitch.
To do this you must enable CUBE on your 2811 and use these special commands:
voice service voip
media flow-around
allow-connections sip to sip
signaling forward unconditional
sip
rel1xx disable
header-passing
midcall-signaling passthru
pass-thru headers unsupp
pass-thru content unsupp
pass-thru content sdp
I don't remember if we have already try this solution.

Vg 224 fax receive intermittant smudged lines
We have a vg 224 configured as sccp to connnect to fax machine and the incoming PRI was controlled by Cucm 8.5 via MGCP. And tried all combinations, the RICOH machine still gets smudged lines intermittantly. Here is the configuration of vg224. Please help:

Fax T.38 support on TDM/IP GW
Hello gents,
I have a customer which I need to provide a Trunk SIP to Service Provider. The connection to PBX (Alcatel OXE R10) will be done using E1 interfaces (alcatel is not IP Enable).
I have a Cisco 3945 ISRG2 that make conversion between E1 (ISDN) interfaces and SP SIP network.
Fax is an important subject for the customer and I have some questions on this item:
- for T.38 fax support, I need to have DSP configured (T.38 is medium complexity codec).
- T.38 work in fax-relay mode, correct?
- They have SG3 fax. To enable fax calls at SG3 speed, I need to support T38 v3.0 (on all endpoints / GW) and enable fax pass-through. Correct?
Issue is that I don't support fax pass-through on SP Voice network.
So final question is: do I support SG3 fax calls (maybe by lowering speed to G3) if I configure T38 fax-relay on my GW? Is there any consideration I need to take into account (DSP, Codec...)?
For example, on my GW, I will have 240 simultaneous voice calls and 80 fax calls.
for DSP calculation, I have take 320 low complexity calls and added 80 transcoding sessions to medium complexity.
Is it correct or do I need to select 240 low complexity calls and 80 medium complexity calls and no transcoding (DSP for transcoding included in medium complexity calls)?
Thanks for your help.Hi,
You can try the follow lines of config on your ISR, these are for a gateway running H.323. what is your current DSP/PVDM ration? -

I almost always force my SG3 fax calls back to G3. If you want to do this as well add the following

I inherited a HP 1240 FAX machine; I would like to print a printer self-test report.It has the ink cartriges installed and the paper tray loaded. When I plug it in and turn it on it displays 'Initializing'; then 'Phone Number'. Whether I enter a phone number or not, when I press the 'OK' or 'Setup' button I hear 3 quick beeps and nothing happens. I cannot find where this is discussed in the manual or the Setup Poster.Perhaps I need to be connected to a phone line and this is the number of that line.
Hi , Welcome to the HP Support Forums! I see that you would like to get your HP Officejet 7612 Wide Format e-All-in-One faxing and would like to print a test report. I would like to assist you. When the printer is initializing, it needs to complete that process before you can do anything else. If the printer is stuck in that mode, I would try a Hard Reset. It goes through initialization to calibrate the cartridges, for best print quality. I would do a Hard Reset to see if that will resolve the issue.
Leave the printer on and unplug the power cable from the printer and wall outlet for 60 seconds.
Then reconnect the power cable to the printer and wall outlet rather than a surge protector.
This ensures the printer is receiving full power and may help this situation.
In order to fax from the HP Officejet 7612, it requires an active phone line. Preferably a dedicated phone line. I would try the steps within this guide, HP Officejet 7610 Wide Format e-All-in-One Printer Series (H912) - Cannot Send or Receive Faxes.The printer cannot send or receive faxes.
Try the following solutions in the order presented to resolve the issue. Solution one: Print a fax test report Run a fax test report to determine the faxing status on the printer and whether or not it is configured correctly to send and receive faxes.From the Home screen on the printer control panel, touch the Right Arrow (), and then touch Setup ().Touch the Down Arrow (), and then touch Tools.Touch the Down Arrow (), and then touch Run Fax Test. The printer prints a fax test report.Touch OK.Review the report.If the fax test indicates that it does not detect a phone line or dial tone, continue to the next solution.If the results of the fax test are All Pass, skip to the Configure the fax for sending and receiving section in this document.Solution two: Check the fax connectionsUse the following steps to check the physical connections, and then test the fax. Step one: Check the physical connectionsDisconnect the telephone cord from the printer and wall jack, and then examine the connector on the end of the cord. Make sure that the cord has only two wires. If you see four wires, replace the cord with one containing only two wires.Figure : Example of a two-wire connectorFigure : Example of a four-wire connectorReconnect the telephone cord to the wall jack, and then reconnect the other end of the telephone cord to the port labeled 1-LINE on the rear of the printer.Figure : Connect the phone cord directly to the wall jackWall jackTwo-wire phone cordRemove the plug from the port labeled 2-EXT on the rear of the printer, and then connect a single-line telephone to this port.Figure : Connect the single-line phone to the 2-EXT portWall jackTwo-wire phone cordSingle-line telephoneIf other devices need to use the same wall jack, make sure that they are connected to the 2-EXT port on the rear of the printer.Figure : Connect other devices to the 2-EXT portWall jackTwo-wire phone cordAnswering machineSingle-line telephone NOTE: Click here to review detailed setup instructions for other connection configurations.Pick up the telephone receiver, and then listen for a dial tone. Make sure that you can dial out using the telephone keypad.If you hear a dial tone and you can dial out using the telephone, the printer is connected correctly to a working telephone cord and telephone jack.If you do not hear a dial tone, check the configuration again and make sure that it is set up correctly.Step two: Try to send and receive a faxTry to send and receive a fax.Show me how to test fax functionalityIf these steps resolved the issue, you do not need to continue troubleshooting.If the issue persists, continue to the next solution.Solution three: Configure the fax for sending and receiving Use the following steps to configure the fax for sending and receiving.Step one: Configure the fax for sending and receivingChoose one of the following options depending on your fax connection.Option one: Configure for a Voice over Internet Protocol (VoIP) systemOption two: Configure for a Digital Subscriber Line (DSL) Step two: Change the Rings to Answer settingFrom the Home screen on the printer control panel, touch the Right Arrow (), and then touch Setup ().Touch Fax Setup, touch Basic Fax Setup, and then touch Rings to Answer.Touch the Down Arrow () until the Rings to Answer setting is either 1 or 2 rings. Select at least one more ring than the phone answering machine setting, if connected.Touch Done.Step three: Change the Distinctive Ring setting NOTE: Only set a distinctive ring pattern if your phone service features the distinctive ring service. For more information, contact your telephone service provider.From the Home screen on the printer control panel, touch the Right Arrow (), and then touch Setup ().Touch Fax Setup, touch Advanced Fax Setup, and then touch Distinctive Ring.If prompted, touch Yes.Select the ring pattern assigned by the telephone company.If you know the ring pattern that the telephone company assigned to your fax number, select that ring pattern.If you do not know the ring pattern assigned by your telephone company, touch Ring Pattern Detection, and then follow the on-screen instructions.Step four: Try to send and receive a faxTry to send and receive a fax.Show me how to test fax functionalityIf these steps resolved the issue, you do not need to continue troubleshooting.If the issue persists, continue to the next solution.Solution four: Temporarily remove any other devices from the telephone line, and then reset the printerUse the following steps to remove any other devices from the telephone line, and then reset the printer. Step one: Remove any other devices from the telephone lineIf any other devices, such as a telephone, a telephone answering machine, or a modem, are connected to the telephone line, remove each device. NOTE: Remove each device even if the device is in another room connected to another wall jack or connected using a line splitter.Connect the telephone cord to the wall jack, and then reconnect the other end of the telephone cord to the port labeled 1-LINE on the rear of the printer.Figure : Connect the phone cord directly to the wall jackWall jackTwo-wire phone cordStep two: Reset the printerPress the Power button to turn on the printer.With the printer turned on, disconnect the power cord from the rear of the printer, and then unplug the power cord from the power source or electrical outlet.Disconnect the USB or Ethernet cable from the rear of the printer, if you have a cable connection to the printer.Wait 60 seconds.Reconnect the power cord to the rear of the printer, and then reconnect the USB or Ethernet cable.Reconnect the power cord to the wall outlet. Bypass any surge protectors.If the printer does not turn on by itself, press the Power button to turn it on.Try to send and receive a fax.Show me how to test fax functionalityIf these steps resolved the issue, you do not need to continue troubleshooting.If the issue persists, continue to the next solution.Solution five: Service the printer If you have completed all the solutions listed above and are still experiencing a problem, continue to the Service the printer section at the end of this document. Print a Printer Status ReportTo make sure that the hardware functions correctly, print a Printer Status Report as a test page.Load plain white paper in the tray.From the Home screen on the printer control panel, touch the Right Arrow (), and then touch Setup ().Touch the Down Arrow (), and then touch Reports.Touch Printer Status Report. The test page prints.Figure : Printer Status ReportIf these steps resolved the issue, and the test page prints, there is no need to continue troubleshooting.If the issue persists, continue with the next solution.If the test page does not print, continue with the next solution.
Hope this answers your question. Thank you for posting! -
The configuration below is for SIP Trunk, but having issues with Faxing. It dials fine, but then sender receives an error, and it doesn't even get connected.
Can someone shed some lights.
See Attached ConfigUnder your sip dial-peers you don't specified a fax protocol transmission method so the voip service voip fax method is use. Nothing is specified in voice service voip and so the default is use:
Defaults
cisco fa relay for all other platforms
none for the Cisco AS5350, Cisco AS5400, and Cisco AS5850
Does destination sip peer support Cisco fax relay?
If no try to use t38 standard method:
codec g711alaw
fax rate 9600
fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback pass-through g711alaw
no vad
If no relay method is supported try to configure pass-through:
codec g711alaw
fax rate disable
fax protocol pass-through g711alaw
no vad
see these commands also:
"bearer-cap speech" command under each voice-port;
"network-clock-select 1 T1 0/0/0" enter this command for each interface that is to receive faxes specifying a different priority; -
Noting that Apple no longer offers an external USB fax modem product, are similar kinds of devices (like, for example, USRobotics5637 or Zoom3095) reliable for sending (via the print menu in OS X 10.6.x applications) and receiving?
An existing "automatic fax switch" is already connected to the landline, and it routes incoming calls now to the phone handset (after initially listening for incoming fax handshaking signals, which it is assumed would be routed to the iMac -- where they are archived and displayed is yet to be determined) or to the voice answering machine if the handset isn't picked-up after a few rings. This has been serving admirably as a way to screen incoming calls, BTW!)). My Internet connection is an ISP DSL, which wouldn't come into play if I'm sending/receiving fax via landline, at "dial-up" speeds and protocols through te external USB fax modem, as I understand it.
My understanding is that the USB external fax modem would be connected to a USB port (USB keyboard or rear panel of the iMac) and the RJ11 connector on the other end of that fax modem would be connected to RJ11 "fax modem" receptical on the existing "automatic fax switch". I'm guessing that the "automatic fax switch" would go off-hook and dial up the phone number of the distant fax machine, from phone number data provided in the "send a fax" set-up invoked when "send a fax" is selected as a "print" option in an OS X 10.6.x application.
Please advise if the equipment and scenario described, and elaborate on anything I'm missing, will work for the intended goal.
thanks,

Faxes are aborted after communication is established.
I used to successfully send faxes using the fax function in the print window. However, for the last few months, and for no apparent reason, the fax function has been aborting all attempted transmissions after apparently beginning transmission.
The function successfully makes contact with the receiving number, and then appears to start faxing. It then stops faxing, without stating whether it has finished faxing successfully.
The aborted fax then remains in the queue, with "hold until xxxx", i.e. a period of 5 minutes which is when it will automatically try again. When it re-tries, the same failure occurs.
It also displays a fax protocol error.
The intended recipient does not receive a fax.
My iMac has a v.92 modem. Nevertheless, I did try faxing with the v.90 modem script (which can be selected in Network Preferences), but faxes were still aborted in the same way.Juan,
I will find out from our programmers if we can implement the suggestions. I have came across the Paid solution earlier today, but will have to investigate further.
I will let you know what option was taken and what the outcome was. -
Hello All,
I have an issue with fax, it is connected to an fxs port on my h323 gateway. When a call comes from PRI and get connected to fax after I hear the fax tone the fax drops. IOS is Version 15.0(1)M4, and DSP is PVDM3.
My analysis:
The external calls hit gateway and it matches the pots dialpeer where my fax connected to. From the "debug voip vtsp all", I see Primary Fax Protocol=CISCO_FAX_RELAY, which is not enabled and we are using T38 relay and modem passthrough method for faxing. I believe PVDM3 does not work with Cisco Relay and couldn't allocate any dsp resources for the call and it drops. But still I wonder how gateway takes cisco relay.
Config:

I have converted the port to MGCP and found its working, while faxing I see vtsp outputs

Can some one kindly suggest how to make it work on H323, also how we can force disabling cisco fax relay?As I mentioned earlier, we are using MGCP for that particular fax port and the gateway we use as H323.
Even I'm not pretty sure about using mixed protocol, I believe this gateway gonna used to support call center calls. SInce MGCP is easy for configs they might have confiugred only the port as MGCP endpoint.
Now its not working with both the cases, not in mgcp as well as fallback mode. Can you reveiw the debugs and see why I have to remove "modem passthrough" command from voice service voip section which of our standard config and works well with all other gateway of ours. Please help here. -
Can't receive fax LaserJet Pro MFP M127fw
While I can send faxes on my LaserJet Pro MFP M127fw, I can't receive them. I've downloaded the newest software & drivers, and the LaserJet Firmware Update utility, and run the fax test, with the report indicating it passed.
Hello @V122,
I'm sorry to hear that the reset made no difference.
Because your fax machine will manually answer faxes we know that the fax modem in your printer is functioning properly. In saying that, I did a bit more research into the Fios phone line that you're using and I do believe that your issue lies with your digital fiber-optic phone line.
Faxing is old analog technology. Nowadays many phone providers offer digital phone lines (like your Fios line). These digital phone lines should work OK with your fax machine. However, there is a lot more static noise and interference on those digital phone lines that cause fax receiving issues. Because your fax can manually answer we know, as I previously stated, that the fax modem is functioning. However, the fax signal isn't strong enough (probably due to digital interference) to prompt your machine to wake up and automatically answer the fax. Simply stated, your machine does not detect a fax coming through.
According the the User Guide for your printer: "HP products are designed specifically for use with analog phone services." Source: User Guide: Page 110 (120-128)
Because Fios operates like Voip (Digital internet based phone line) we could try to lower your Fax Speed to Slow on your printer to give your fax machine more time to 'listen' and 'connect' as the digital signals transfer much faster than analog signals.
How to Lower Fax Speed:
Select the Setup button on your printer
Right arrow to Fax Setup
Right arrow to Advanced Fax Setup
Select Fax Speed and alter this to Slow
Once the Fax Speed has been changed to slow, please try to receive a fax automatically again to see how your printer responds.
Please let me know if the Fax Speed adjustment resolves your issue. Good luck!
