FXO Line Hunting solution

Hi,
My voice gateway is equipped with 8 FXO port hence 8 analogue lines. All numbers are being used for incoming and outgoing. For outgoing, one trunk group is fine to switch the line.
Now, if one user has established call outside on port 1. Simultaneously, outside caller calls that number and it gets busy tone resulting he has to wait. Any idea, that for incoming calls, if first port is busy then it can switch to other free line

Hi
You can check the below , please.This is a trunk group which will make all ports as one trunk.
voice-port 1/0/0
trunk-group VoiceGroup
voice-port 1/0/1
trunk-group VoiceGroup
voice-port 1/0/2
trunk-group VoiceGroup
voice-port 1/0/3
trunk-group VoiceGroup
dial-peer voice 100 pots

Note: I think you have to check also with your ITSP , if this can be procced. ITSP should be able to do something like inorder calls based on the available ports. I think you can manage outgoing calls , but for incoming you have to check with ITSP.
Thank you

4 FXO lines on a 504G

So I have setup the UC320 with 4 FXO trunk lines and deployed 12 504G phones. I assumed since they are 4 line phones that they would be able to see all 4 trunk lines at the same time.
Upon getting everything configured I have discovered that the first programmable button seems to be permanently assigned to the users personal extension. Which leaves only 3 remaining buttons for shared FXO lines. So I was forced to make the 4th trunk line a hunt group with all the phones.
It's such a simple setup I'm surprised the 4 line IP phones can only actually monitor 3 of the shared trunks leaving the 4th working but hidden from view. There doesn't appear to be anyway to change or remove the first button from being the personal extension button, which I find to be redundant.
All I would like is to have the phone monitor/display the status of all 4 trunk lines on the phone. Any help for this situation? Maybe I'm overlooking something obvious here?

Adam,
You are correct, even in Key System Mode the UC320W assigns an extension on the first line button. This allows for internal dialing between users without utilizing a Shared FXO line.
The other 3 line buttons can programmed via the UC320W.
The SPA504G is a 4 line phone and can be configured with multiple SIP based call control systems, when used with UC320W then the phone allows for 3 user programmable line buttons.

Randy

More than 8 FXO lines on the UC540

Hi,
I am looking for possible solutions for adding an additional FXO line to a UC540 as well. Mine already has the additional VIC2-4FXO module and all FXO ports are used. From reading the Manuals, Release Notes, and Forums, it sounds like the 8800 will only support additional FXS ports. I have not found a solid answer as to why that is. It seems like it would be a hardware/platform overload issue for the UC540 to support more than 8 FXO lines. Is this assumption accurate or is there something we can do about it?

I appreciate your prompt response. I know what ISDN BRI and PRI signaling is. However I am not sure I understand your response. Could you please elaborate on what you mean by "upgrade to ISDN PR".

Where can i change the line hunt circulation time?

Hi all,
I've configured line hunt in CUCM v9. The customer asked me to change line hunt circulation time, i know the option to change waiting time in queue, but i don't how to change hunt circulation time, does anybody know that?
Thanks in advance,
Eric

Hi George,
No option to change the algorithm under the line group settings, could you please tell me the detail? i added 1200s maximum wait time in queue under the hunt pilot settings.
Thanks.

FXO line in use voltage

I have an incoming POTS line connection to an FXO port on a 1760 gateway. This POTS line is only providing -24 voltage rather than the normal -48 voltage. This seems to be preventing the FXO interface on the router from sending DTMF that is acceptable to the POTS line. I have read that I need to change the FXO line in use voltage on the gateway to a lower value in order to allow DTMF to pass correctly to the POTS line. Does anyone know how to change the FXO line in use voltage, or know if it is possible to convert the -24 to -48 between the FXO port and POTS line?
Thank you,

Nick, to my knowledge the router never detects dial-tone, although the vpm debug print a string to that effect.
What the router does for outgoing calls, is detecting current loop after going off-hook. So for example when the FXO port is not connected, you are able to tell, again by looking at the output of debug vpm signal.
Instead, for incoming calls, router detects AC ring current and goes off-hook without further check.
So if my theory here is that the attached equipment is not providing correctline voltage or loop current, if I'm correct the proof would be identical output of "debug vpm singal", either with the line connected, or disconnected.

Need a sample cme with multiple fxo ports, hunt fashion

hi,
anyone kind enough to provide a sample working configuration of multiple fxo ports (each being a pstn line) and I assuming the telco is doing hunting...
so let's say 4 lines, if line 1 is busy the call is sent by the telco on line 2 and so on...
incoming and outgoing.
thank you very much!!
I did google it and can't find anything with multiple fxo ports.

Blank screen showing battery sign with red line - possible solution

Hi to everybody,
I had a little issue with my Blackberry curve 8350i, but I think this might go with several models. One day my Blacberry updated an application and restarted, but when restarting suddenly I got a blank screen showing a battery sign with a red line. I took out the battery and put it in again, but no luck. I searched on many forums if anyone experienced the same as me. I found a lot of topics but no solution. I called tech support of my service provide and fortunatelly I talked to a tech guy who was willing to help. He said that this error message usually might appear when the battery is faulty, not original (not my case) or device is not working, but before taking a final statement he wanted me to try something first. He said to take out the battery, the SIM card and any extern memory card. Then to clean any contacts with air. I followed his instructions and after that the device worked again without any problems. I would like to share this experience on this forum maybe this will help other to to solve similar issues.
Best regards,
Julix

Excellent advice! I just had the same thing happen to me and your post solution fixed my phone.

BTE 1650 LINE ITEM DISPLAY: Add to data per line - possible solution

Hello,
I would like to populate field payment order (Pymt.order) in custom transaction FBL5N
I have read that it should be doable using BTE 1650 LINE ITEM DISPLAY: Add to data per line but I am not sure if 1650 is correct one and if its proper solution for this purpose.
Could you please advice?
Thank you in advance!
Michal

i have the same problem , i used BTE and the fields appear but without data . which table or code i will use to in FM to display data in transaction.
thanks all for help

Selective ringing of FXO lines on line share buttons

I have a customer that wants to have the UC540 emulate their existing Norstar KEY system. They have 6 lines and 15 stations. I have already setup and tested a hybrid KEY system in my lab with FXO's as shared lines https://supportforums.cisco.com/docs/DOC-15755 . This works fine. The only problem is ican not select several phones to ring and several phones not to ring when a call comes in to the FXO trunk. Either all the phones have to ring or all the phones are silent ring, not a mix of both. Is there a way around this? Perhaps in CLI.

You can comfigure individual phones sharing a DN, with 's' button for silent ring. Note this is a CLI command, I don't know and can't answer if that can be done using CCA.

Configuring FXO Line

Hi,
I have a CCME 4.2 installed on a 2821 Router and FXO connected to it. I had connected PSTN line on the FXO.
dial-peer voice 10 pots
destination-pattern 9........
port 0/3/0..
I am unable to make outgoing/ incoming calls. pls help....

Hi Pradeep,
What number are you dialing for outbound calls? Should that call go out of dial-peer 10?
This link shows a sample configuration of configuring a CME router to allow basic inbound and outbound calls.
Configuring SCCP Phones for Making Basic Calls:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmebasic.html#wp1043996
If after configuring everything you still have the problem, post your updated configuration, as well as the output of debug voip ccapi inout, collected while recreating the problem.
Hope this help.
Regards,
Michael.

FXO lines locking up

I have a 320 that is running latest firmware but keeps locking up FXO ports. If I reboot the system the lines free up and calls flow for about a month then it locks up again. I have done the impedance testing per port and adjusted per test results but it doesn't seem to help. Anyone else run into this?

Take a look at this document:

Too many information in 1 table line - alternative solution ?

Hi,
Just join today since i am new to Adobe LifeCycle.
I am using Adobe Life Cycle 8.1.2
As the title explains, currently i am designing a interactive adobe form (orientation: Portrait) which has a table with "add/remove" button. The "add/remove" works perfect (i can add line or remove line from the table).
The problem is I have too many information (read: columns) in 1 table line. In results:
1. Table line is not sufficient to display all information, OR
2. I can squeeze all columns into 1 line and play around with smaller font size. But the form looks ugly.
Has anyone encountered this kind of situation before ?
Can you share your design (if possible attached the form) for similar situation ?
Any bright input/idea are most welcomed.
Thanks In Advance !
Note:
1. Landscape is NOT an option.
2. I still want to have "add/remove" functionality.

Hi,
Suppose you have set the the no of columns to 6 for any row . 1st row has 6 columns. 2nd row has 6 columns intially. But you can merge some of the columns to make it one. Selects the columns you want to merge.Then Right Click -> Merge cells. But this may lead to another problem about the caption of the columns. But if it's text field or same type of field you can specify the option to set the caption as on top.
Thanks,
Bibhu.

When I print to Acrobat from Quickbooks, Acrobat adds heavy lines. Solutions??

When printing to file from Quickbooks to Acrobat, Acrobat has begun to add three heaviy lines. Always in the same location; like three sides of a box. Initially the application worked fine. But since this problem started it has been consistant. I have Windows 7. Thank you.

This forum is for printing from Acrobat, not to Acrobat which actually uses Acrobat Distiller. I will move your post to the appropriate forum.
The problem may be due to Acrobat/Distiller or it may be the output that Quickbooks is generating.

CCME FXO lines

Hello --
I am having issues with my CCME dropping calls. A user will try to place a call but it'd drop before connecting. Then they press redial and it works fine. I'm currently suspecting that it's a supervisory disconnect issue and have added the following commands:
supervisory disconnect anytone
timeouts call-disconnect 5
timeouts wait-release 5
I have a feeling that this is the way to go, any thoughts?
Thanks,
Ohamien

Hi,
sometimes it depends on the ISP. You should see the frequency behavior, and then create a customized voice class. You can record a phone call, and once you capture the audio of the disconnect frequency you can apply that measures to the configuration.
Firt delete the lines that you configured, because the supervisory disconnect anytone some times made me drop some phone calls too.
Try this example that worked fine for me.
Let me know if it works 4 u.

7 digit dialing on FXO lines for UC320W

Located in the Jacksonville, FL USA area, cannot seem to create a dial plan for 7 digit dialing. Area code is (904) and I don't see an option where to change from 10 digit to 7 digit outbound dialing.
Am I missing something?

Hi lance-ten,
Please go to Region page, change the dial plan from 10-digit to 7-digit and provide the default area code which is 904 for your case. Then you need to apply the configuration to make it effect.

Wendy
