VG 224 Voice Gateway using MCGP or fax

Does anyone have a experience or a config for running MGCP on a VG224 voice gateway (using it for inbound/outbound fax)to Call Manager? I've set up SCCP and it worked initially but in production it drops calls and does not respond after reboot without re-enabling SCCP and STAPP

I deployed 5 of these to service a mix of phones and faxes a few months ago using MGCP.
I used fax passthrough; we've had 0 problems so far with the setup.... customer has had several power cuts and no startup problems.

VG 224 Voice Gateway using MCGP for fax

Does anyone have any experience or configs to set up a VG224 Voice Gateway to manage via Call Manager 4.1 using MGCP (for inbound/outbound fax)? SSCP is currently set up, but seems unstable.

try this link for VG 224 support on MGCP

Voice gateway SPA8000 problem sending faxes.

Hello, I am a representative of the corporation Kazakhmys using the whole range of your devices. The problem is as follows: Voice Gateway Cisco SPA 8000 does not send faxes to voice gateway Grandstream GXW4232. The problem occurs only if the two voice gateways work with each other. The call comes to the SPA 8000, but after lifting the handset, the session immediately reset. What settings I need to change?

It seems you have RTP packet Size set to 30ms. It's not optimal even for voice call. You should not exceed 20ms for voice, for the fax I propose you to use 10ms.
Note it may not solve your problem, but it increase reliability of fax session.
But now back to the issue. If I understand correctly, the attached log has been captured on
Cisco-SIPGateway/IOS-15.2.4.M7
OK. It seem that most important line of such log is:
068963: Feb 24 05:50:16.778: //6170583/D6D178518A93/CCAPI/cc_api_call_disconnect_done:
Disposition=0, Interface=0x160DE9D8, Tag=0x0, Call Id=6170583,
Call Entry(Disconnect Cause=3, Voice Class Cause Code=0, Retry Count=0)
If I understand correctly the log, the call has been terminated by SIP Gateway.
I see no apparent issue with ATA8000 (not counting the Packet Size value mentioned on top). There is a problem with SIP Gateway. Unfortunately, I'm not expert on the matter nor this forum is best forum for question related to SIP Gateway. You should ask on IP Telephony forum instead.

Can't establish a Voice gateway (cisco 2911) using SIP with CUCM 9.1

I have configured a Cisco 2911 as a Voice Gateway using SIP (the configuration is attached), but unfortunately can't establish a test call to a phone (CUPC 8.6 SCCP) using csim start. I have done logging the ccsip debug and ccapi debug and attached them. Could anyone help me to solve this problem?

I just did some research on my end and csim is not supported for SIP. The Invite will never be created and sent to the CUCM to initate the call. It disconnects in the router itself with normal cause.

Call Manager register fxs port with voice gateway- problem

I have a CUCM 6 and a Voice Gateway V224. I've configured the voice gateway's voice FXS ports as MGCP.
I have a Voip connected and registered to the CUCM and a Pots phone connected to the Voice Gateway.
If i dial from the Voip to the Pots phone it rings. The problem is that i cannot ring from the Pots to the Voip phone.
I have no dial tone.
If i write no shut down on the voice port i have a tone. If i configure mgcp on the voice port i have a busy ringtone.
I've entered no mgcp and mgcp commands and i've reset the voice gateway.
How can i call from the pots to the voip phone?
The ios version on the voice gateway is Version 12.4(22)T4.
Here is an outghtput from the Voice gateway.

Is your campaign using CPA? If so, what's the behavior if CPA is not enabled?
I think the best thing to do is to run a trace...
Call Manager > Cisco Unified Serviceability > Trace > Configurations
Select a CUCM server - any subscriber would work.
Service Group - CM Services
Cisco CallManager (Inactive)
Enable SIP Stack Trace and apply to all nodes. Download and install RTMT
Make a bunch of outbound tests and then open RTMT > Trace & Log Central > Collect Files > Check "All Servers" for Cisco CallManager > Next > Next > Relative Range if you made the test calls within the last X minutes, otherwise you can set a From and To datetime. Click Finish and go through your SDL logs and see what errors you find and post them here.
Also, make sure your phone is in the correct CSS in Call Manager

Rightfax server with Brooktrout Analogue interfaces to cisco Voice gateway

Hi,
I have Rightfax server that will be connecting into a Cisco Voice Gateway via analogue interfaces. The Brooktrout card is model : Brooktrout TR114-P4L. Could anyone advise what type of VIC module I require. I will need to support DID and DTMF-relay on these interfaces.
thanks

We have made these work a few times in the past. The cards expect work as a FXO interface, and expect battery feed from the external device. To make these work on IOS gateways, use a FXS card on the router, and H323 operation to allow the POTS dial peer to send digits out the voie port.
The cards will answer on ring signal from the FXS port and expect DTMF digits to route the call to the correct fax mailbox number. This is why you need H323 operation - MGCP will supress the DTMF tones from being sent out the voice port. You also need a 'prefix ,,' to add a delay as the cards are a bit slow to answer.
A config like this should work -
dial-peer voice 1000 pots
description - fxs port to fax card
destination-pattern 1...
port 0/1/0
prefix ,,1
This will send numbers in the range 1XXX towards the fax card

Where can I learn the structure of Voice gateway ?

I'm making a essay about Structure of Voice gateway: hardware and software construction. I can not find any books or any manual deal with it . So,can someone give me more information about structure of voice gateway or give me some useful resources please?
I'm waiting for your replying.

Cisco doesn't make public the software structure of their products; to a certain extent it can be inferred from documentation and familiarity with the product, but probably not enough for an in-deep analysis.
For your task, I suggest you focus on some open-source development of GW, that has no secrets.
Hope this helps, please rate post if it does!

Setup of 2 B-channel transfer (TBCT) on Cisco Voice Gateway

Hi all,
In my scenario, I have several remote locations, each with their own T1-PRI connection to the PSTN via Cisco voice gateways.
The call flow has the caller calling a PSTN number at the remote location. This call hits a CUCM translation pattern and is immediately hairpinned/tromboned out to a PSTN number located at the UCCE central location.
The customer would like to perform a 2 b-channel transfer back up to the CO switch, to free up B-channels to the remote location.
My question is this: Assuming my switch type is supported and the PSTN provider supports 2 b-channel transfers, do I simply need to add "isdn supp-service tbct" to my serial interface configuration?
I have seen discussions that it is as simple as this, to needing some tcl/xml code, to also requiring aaa to be setup.
As there are over 100 locations being considered for this enhancement, the customer would like to know if it is 15 minutes or 2 hours per location to implement.
Thanks,
Joe

Thanks Paolo,
That was my expectation.
They have this going on the VG's utilized by CVP, so I will ask them to review the XML in use there for tweaking for the remote locations.
Thanks again!
Joe

How to verify voice channels on voice gateway

Hello,
I am in the testing phase of deploying a 2921 voice gateway with 2 PRIs. After connecting the T1s, how do I verify if all the channels are up and ready for use? Also, how do I verify if clocking on the T1 interfaces are configured correctly?
This 2921 is a replacement for a 2811 currently being used. When I login to the 2811 via SSH, I see this:
560240: Aug 13 20:37:24.368: %ISDN-6-CONNECT: Interface Serial0/2/0:3 is now connected to 3854143418 N/A

How do I do that with the 2921 in an SSH session? I've enabled "logging monitor" and "term mon" but I still can't see messages like that.
I thank you very much for your time.

Hello,
To check clocking you can use the "show network-clock" command. For example:
SiteA-RTR#show network-clock
Network Clock Configuration
Priority Clock Source Clock State Clock Type
1 T1 0/0/0 GOOD T1
10 Backplane GOOD PLL
Current Primary Clock Source
Priority Clock Source Clock State Clock Type
1 T1 0/0/0 GOOD T1
The above is an example of a "good" configuration, assuming that T1 0/0/0 is the controller terminating the line from your carrier. In your case, it would be T1 0/2/0 or 0/2/1. You can also look at "show controller t1 [interface]" (e.g. show controller t1 0/2/0) and pay particular attention to "Line Code Violations", "Slip Secs", and "Errored Secs" counters. Note that the "Clock Source Line" status in the "show controller t1" command is not enough to verify you have proper clocking.
Example of a "bad" clock scenario:
SiteA-RTR(config-voiceport)#do sh controller t1 0/0/0
T1 0/0/0 is up.
Applique type is Channelized T1
Cablelength is long 0db
No alarms detected.
alarm-trigger is not set
Soaking time: 3, Clearance time: 10
AIS State:Clear LOS State:Clear LOF State:Clear
Version info Firmware: 20080918, FPGA: 13, spm_count = 0
Framing is ESF, Line Code is B8ZS, Clock Source is Line.
CRC Threshold is 320. Reported from firmware is 320.
Data in current interval (483 seconds elapsed):
3 Line Code Violations, 4 Path Code Violations
207 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
206 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 109 Unavail Secs
To make sure the clock is set correctly, look at the "network-clock-participate" and the "network-clock-select" commands.
For the ISDN status information, you can use "show isdn status". For example:
SiteA-RTR(config)#do sh isdn stat
Global ISDN Switchtype = primary-ni
%Q.931 is backhauled to CCM MANAGER 0x0003 on DSL 0. Layer 3 output may not apply
ISDN Serial0/0/0:23 interface
dsl 0, interface ISDN Switchtype = primary-ni
L2 Protocol = Q.921 0x0000 L3 Protocol(s) = CCM MANAGER 0x0003
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 0 CCBs = 0
The Free Channel Mask: 0x800000FF
Number of L2 Discards = 0, L2 Session ID = 15
*Note: The above is output from a gateway provisioned to use MGCP.
For all gateways, just make sure that Layer 1 is "ACTIVE" and that Layer 2 has "MULTIPLE_FRAME_ESTABLISHED".
You can also use the "show isdn service" command to look at status for individual B-channels.
SiteA-Rtr#sh isdn service
PRI Channel Statistics:
%Q.931 is backhauled to CCM MANAGER 0x0003 on DSL 0. Layer 3 output may not appl
ISDN Se0/0/0:23, Channel [1-24]
Configured Isdn Interface (dsl) 0
Channel State (0=Idle 1=Proposed 2=Busy 3=Reserved 4=Restart 5=Maint_Pend)
Channel : 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4

State : 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2
Use the "Channel State" and "Service State" to verify things are what you expect.

How to make CUCM as a TFTP server , then copy files to Voice Gateway ?

how to make CUCM as a TFTP server , then copy files to Voice Gateway ? anyone knows?

Hi,
Please check the following link
http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/6_1_1/ccmsys/cucm-accm-611/a02tftp.html#wp1023004
Understanding How Devices Access the TFTP Server
You can enable the IP phones and gateways to discover the TFTP server IP address in one or more of the following ways, depending on the device type:
•Gateways and phones can use DHCP custom option 150.
Cisco recommends this method. With this method, you configure the TFTP server IP address as the option value.
•Gateways and phones can use DHCP option 066.
You may configure either the host name or IP address of the TFTP server as the option value.
•Gateways and phones can query CiscoCM1.
Ensure the Domain Name System (DNS) can resolve this name to the IP address of the TFTP server. Cisco does not recommend this option because it does not scale.
•You can configure phones with the IP address of the TFTP server. If DHCP is enabled on the phone, you can still configure an alternate TFTP server IP address locally on the phone that will override the TFTP address that was obtained through DHCP.
•Gateways and phones also accept the DHCP Optional Server Name (sname) parameter.
•The phone or gateway can use the value of Next-Server in the boot processes (siaddr).
Devices save the TFTP server address in nonvolatile memory. If one of the preceding methods was available at least once, but is not currently available, the device uses the address that is saved in memory.
You can configure the TFTP service on the first node or a subsequent node, but usually you should configure it on the first node. For small systems, the TFTP server can coexist with a Cisco Unified Communications Manager on the same server.
