Voice Gateway echo problem

Hi,
My Cisco 2821 router have 2 PVDM2-64. The "sh call active voice echo-cancel summ" result are A/F :
Voice-GW#sh call active voice echo-can summ
CallID     Port         DSP/Ch   Codec    Ecan-type Tail Called #    Dial-peers
0x111BDFE 0/1/0:15.30      0/1:5    g711ulaw SW-Extend 64 ms *29277728   797/22
0x111BEB2 0/1/1:15.31      0/1:1    g711ulaw SW-Extend 64 ms *082311888 797/40
0x111BEB4 0/1/0:15.31      0/1:2    g711ulaw SW-Extend 24 ms *62379      797/26
We find that the call at port 0/1/0:15.31 have echo problem. We monitor several times and find the echo occured when the DSP/Ch is 0/1:2 or 0/2:2. Please help to mention me the DSP/Ch 0/1:2 or 0/2:2 is which PVDM2-64? Does it mean one of my PVDM2-64 failed? If yes, which one of PVDM2 failed?
Best Regards,

We tried to upgrade IOS from 124-15.T4 to 124-25g and monitor about one days, the echo problem seems not occurred again. Please help to mention me why you recommand to upgrade IOS? Thanks a lot...

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.

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.

The CUCM 6 is registered with 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

Echo problem

IP phone user hears an echo of his voice on a call to a PSTN phone. It looks like an issue with the voice gateway. Checked the cisco document
http://www.cisco.com/en/US/tech/tk652/tk698/technologies_tech_note09186a0080149a1f.shtml
Set the echo canceller converge to the highest value (64ms). But the users are still experiencing echo problems.
Attached pls find the output of "show voice active".
IOS 12.4.6T on Cisco 2811
Appreciate any input.

There is a known bug with that version of IOS and the DSPs on it...bug CSCsd54344
DSP: Persistent echo heard on c5510 DSPs with 4.4.13 DSPware or higher
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCsd54344
use show voice dsp group all to see if it is using DSP version 4.4.708. If it is you either need to go up to 12.4.9T (first fixed version) or downgrade the DSP (easiest option) to version 4.4.706.
You can call TAC about getting that file if needed.

IP2IP Gateway Transcoding Problem

I have a test IP to IP Gateway on 2811 with PVDM2-16 DSPs.
The software is c2800nm-ipvoice_ivs-mz version 12.3(11)T7.
Accortding to the documentation it should be able to do transcoding between inbound
and ourbound call legs (Transcoding G.711-G.729). However, the configuration guide points to
Configuring Enhanced Conferencing and Transcoding for Voice Gateway Routers chapter
of the Cisco CallManager and Cisco IOS Interoperability Guide. This configuration is for
CallManager transcoders. But I need the gateway to do transcoidng and do so with NO need
for CallManager. The gatway is not registered in gatekeeper also. It should be standalone
and make static routing of h323 calls between endpoints.
I've searched in the documentation but I did not find any configurations
that I can use. I made a lot of tests with diferents configurations but when there is no match
in codec betweend in and out legs (with slowstart) the debug says:
*Aug 18 11:10:03.030: //2546/3AD381928396/H323/cch323_prepare_preferred_codec_list: Check the filter: Not a single match
*Aug 18 11:10:03.030: //2546/3AD381928396/H323/cch323_peer_caps_ind_common: No Matching Codec after filtering. Hence try to find xcoder
When faststart is enabled the two call legs have different codecs in " show call history " but I here strange sounds
which means that there is no proper ( or no at all) transocding in the gateway but the endpints try to decode the incorect codec.
So I don't know if this is some problem in this recent version of IOS or I have to make some reconfigurations or even change the DSPs.
Or may be it's not (yet) possible to to this kind of transcoding and I misunderstood the features description in the docs?
Any ideas are welcome!

I could go out-of-topic, but the best thing (with a reasonable price) I have seen to do codec translation is the MERA MVTS softswitch.
Asterisk PBX can do it as well, but it need licenses for the G729 codec and its H323 support is crappy.

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.

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.

E50 Echo Problem & No Help From Nokia Turkey

Hi,
I'm using Nokia E50 for two months. Whenever I have a call (in or out) am receiving the same complaint from the other side of the line : The guy who is talking with me always hearing his/her own voice during the call. Echo issue.
I've called the Nokia Turkey Call Center they told me that they've never been advised a case for the ECHO problem !!! Apparently they don't even hear the Google since there is hundreds of similar case !!!
I took the phone to the official Nokia Repair Shop they've just checked the software and the patches and all of them were fully updated. Unfortunately they don' have any idea what's going on.
Appreciate if anyone help me out about the issue, otherwise I'm going to give back to phone since it's still within legal warranty period.
Regards

We have seen the same problem with 2 E50s my company has just bought. I thought it was the new BT car kit that people were complaining about until I called my colleague with the new phone for the first time and we got DOUBLE ECHO!!!
The latest firmware does not seem to fix this problem as of Jan 07. Have tried adjusting the volume down to no avail, so no other suggestions, but rest assured you are not alone.

N70 echo problems

Hi everyone!
Have had an N70 for just over a week and am already on my second handset.
When using my phone - the person I am calling complains of a bad echo of their own voice - but it sounds perfect at my end. This is not when on handsfree, but when I make a normal call.
If i turn the phone off and then on again it seems to be ok for a little while, then the echos start again.
Vodafone suggested in the first week that it was probably a mic fault and changed the handset for a brand new one. The brand new one was ok for a couple of days, and now it is echoing again.
Anyone got any ideas why it is doing this?
I do connect to a tomtom Go 500 via bluetooth and handsfree calling on that is fine - the echo is only evident when I'm not connected to the tomtom.
Many thanks
Vicky

I've also had exactly the same problems - along with six N70s, 3 x 3G sims & a 2G sim replacements since 11th January. I've just had the latest software put on my phone & the echo problem started yet again 2 hours later. I have now tried (only yesterday) the phone with bluetooth turned off and so far it's lasted @ 26 hours without an echo.

K860 Echo Problem

Hi everyone,
I just bought my new K860 smartphone last Dec 2012, I didn't notice it until one of my friends told me that his voice is echoing when I call him, I tried to call my other friends and have the same scenario.. Please help.. Thanks!

Have you tried a factory reset to see if it was a setting? If problem exists after a reset, then it would be a hardware issue that would need to be repaired.

E60 echo problem

Hello all,
Whenever somebody call's me or I call them they are complaining that they hear an echo of their own voice.
This problem only occurs after I use my e60 in combination with the integrated bluetooth carkit from Peugeot. When I switch the phone off and on again, the problem is gone.
My phone already has got the latest firmware and I know somebody with the same phone who has the problem with the bluetooth carkit of bmw.
Can somebody help me with this please.
Thanks,
Best Regards

I have the same problem. Called over and over to Nokia.
They are unwilling to solve this. Since the carkit (in my case a Pioneer Bluetooth Radio) is not a Nokia accessoire.
Real pitty and a showstopper for business users like me.

Cisco 2911 Voice Gateway SIP PSTN Calls Fail

Hello All,
    I am having trouble with outboud SIP PSTN calls through a Cisco 2911 Voice Gateway. 2911 VG terminates PSTN SIP Traffic and connects to Avaya CS1000M via QSIG PRI Trunks. When calls are attempted outbound fron the PBX the caller gets a fast busy. Debug ISDN q931 shows the call hitting the 2911 properly, debug voip ccapi inout shows the call matching the correct dial peers and debug ccsip shows the invite to the PSTN Provider SBC, however within the invite the "from" address incorrectly shows the calling number with the provider SBC address (see below). does anyone have any insight on how to correct this? Attached are VG config and Debug isdn q931, voip ccapi inout, ccsip messages and ccsip call. Thanks in advance for any help!!

Troubleshooting SS7 Interconnect for Voice Gateway

Hi
Recently we have implemeted SS7 Interconnect for Voice Gateway Solution in our network.
We are using devices PGW2200, NAS 5400, SLT 2611, 4000 Series S/w and GK.
Customers compalint that they are facing Echo, Clip in Voice and No voice related issues. Can you tell us the commands on PGW/GW/SLT to pinpoint. PGW we are using in Call Control Mode.
Please help.
Thanks in Advance.

Hi,
You can check in the /opt/CiscoMGC/etc directory properties.dat file which has the parameter *.EchoCanRequired which should be set to 1. This can binded by an individual trunk-group as well. Also make sure the voice-ports have the echo-cancel coverage and disable VAD to see if it makes it better.

Site to Site Connectivity Between BE6K and Voice Gateway 2901

Greetings,
Is an Ethernet handoff required for site to site connectivity between BE6K and a voice gateway 2901. My vendor is suggesting that it's required in order for both sites to see the BE6K as one phone system. However, here in lies the problem. I have a point-to-point T-1 between the sites that does not have an Ethernet handoff, just the smartjack to the T-1.
What would I need to get this to work? Have a router at each site? If so, which model? Or is there a component I could add to the BE6K or voice gateway?
Any help would be greatly appreciated.
Thanks in advance.

Ethernet handoff just means that the provider will deliver the circuit using Ethernet. What circuit is your provider delivering for you? Do they manage your WAN? Like I said what you need is ip connectivity between your sites and BE6k. If your T1 connection provides WAN connectivity and you have ip connectivity between the sites, then I don't know what you need any handoff for. The question is do you have ip connectivity between the sites via your T1 connection

Voice Gateway & Gatekeeper On a single Router?

Hello All,
Has anyone had experience with putting voice gateway and voice gatekeeper functionality into one router? We will have three clusters initially (with about 1,000 users worldwide though) and was considering one gatekeeper per cluster for CAC and tail end hop off routing for LD/International calls.
Any guidance on what sort of platform these should be running on if kept separate? DSP resources in them, etc.?
The voice gateways will be a mixture of 2851 and 3800 series routers. Thanks in advance for the help.
Thanks,
Dave

Hi,
I have done this many times in lab, dont know if that will be ok in production if you have a good powerfull problem i dont think that it will be a problem.
About the DSP's maybe you can use the DSP calculator - anyway this refers to many parameters on the network.
BR,
Teo
