Re: [Asterisk-Users] Asterisk and Cisco 7960 problems persist (for me, anyway)
This isn't really the issue. Up until a week ago or so everything worked fine with a hallf duplex hub. Now it doesn't - so I suspect some code change made in * is responsible. I think * must maintain backwards compatibility with existing hardware or many people will get fed up with constant degradation of sound quality.

Re: [Asterisk-Users] Asterisk and Cisco 7960 problems persist (for me, anyway)
Vic, The problem you're having has been discussed multiple times on this list, and can be easily seen using ethereal to inspect the timestamps contained within the rtp packets sent to the 7960 phone. There are several issues involved, including: 1. the cisco phones drop any rtp packet that is not exactly 160 milliseconds between successive packets (thus causing choppy audio). That drop function seems to be the result of cisco changing DSPs in their v6.x code. I've not heard of anyone running v5.x sip code with the problem. 2. iax2 had a bug in it that Mark fixed last month. The bug resulted in iax2/gsm timestamps that were erratic when they should have been exactly 20 milliseconds between successive packets. 3. Code was added to rtp.c about a month or so ago that ties the iax2/gsm timestamps directly to the sip/rtp timestamps. When that code was added, it made the iax2 erratic timestamps and Cisco's dropping of packets extemely obvious to iax2 users. Other non-iax2 users are not impacted by this. Cisco phones seem to be the only ones impacted by this. There are three short term fixes available to you: a. upgrade (or insist your service provider) upgrade their iax2 code. (I don't believe the Stable branch has the fix in it as yet.) NuFone and some others have done that a few weeks ago. b. remove the two or three lines that were added in rtp.c (although Mark is discouraging this approach for other reasons), or, go back to source code cvs from about early March. c. Change the 7960's from v6.x code to v5.x code (and open a trouble ticket with Cisco). I've not heard anyone suggest that dropping rtp packets with uneven timestamps is necessary, a standard, or anything else. Therefore believe it's an anomaly that crept in with the DSP change in the sip v6.x code from Cisco.

What I'm seeing (er, hearing) is really choppy audio.

Brian, Are you having the choppy audio only on iax2 links or on other calls as well? There was an issue with erratic iax2 timestamps which caused the Cisco phones to effectively drop any sip packet that had uneven timestamps causing extremely choppy audio. The choppy audio (as I seen it) was only in one direction (from the iax2 source with the erratic timestamps towards to 7960 phone). If your issue is not associated with iax2, then be aware the Cisco v6.x code changed DSP firmware internally, and any sip/rtp packets arriving with uneven timestamps (within the rtp pkts) will be dropped and cause the choppy audio. You should be able to see the timestamps with ethereal. The timestamp difference between successive pkts should be exactly 160 milliseconds; if its anything else, the phone will drop the pkt. (Not sure if that is a real Cisco bug or a planned change, but it certainly has a hugh negative impact on voice quality.) I'm running CVS-HEAD-05/02/04 with no problems today.

Just an FYI if you can run tethereal -n udp port 4569 And watch the timestamps(should be even 20ms increments per call leg). Both ends will need to be updated also. If not you will get some very strange timestamp issues and jitter and timestamps might not be right. If you have one end on cvs-stable and one on cvs-head you might see this problem also.

Re: [Asterisk-Users] Asterisk and Cisco 7960 problems persist (for me, anyway)
Upgrade each asterisk (iax2) and the problem will go away. As bkw mentioned, the problem sources from the location with the older iax2 code (which probably includes the Stable cvs I believe). NuFone had the problem in mid/late April as well, but they apparently updated their code when the issue was discovered/corrected. Other iax2 providers are likely to source the problem as well.

Do you have a jitterbuffer enabled on your inter-asterisk IAX trunks? If so, try disabling it cleared everything up for me. With jitter buffer enabled using the default settings my audio across the IAX trunk was terrible.
