[Freeswitch-users] G_729 Virtual Server Audio Quality Problem

[Josh Foshee]

Let me start off with the environment that I am using.

I have a virtual server that is hosted on Linode.com. They are running Xen
Server VPS.

The Freeswitch version I am using is FreeSWITCH Version
1.2.0-rc2+git~20120629T194106Z~5f09b40381+unclean~20120630T202857Z

I am using mod_com_g729 with 20+ license installed.

I have two Sip Profiles setup (internal and external). The internal
with authentication is on port 5060 and external with no authentication on
port 5080. They have different codec values for each.

The Sip provider that I use is Flowroute.com

The Leg from Flowroute to Linode I will call Leg A.

The Leg from Linode to phones I will call Leg B.

The problem that I have is that I can setup the pathway with the codec
PCMU. I can place a call and both parties sound find and no audio
problems. I can change the Leg A to g729 and still have no audio
problems. I then change Leg B to g729 and the remote party (the one on the
PSTN network) will hear the site traffic as choppy. The local party will
hear quality issues not as much. It is a constant problem on the remote
party side though.  I then change Leg B back to PCMU and the quality is
great. I change it back to G729 and it goes back to bad audio quality. All
testing was done between 1am to 2am but this was also reproducible during
the daytime. I'm pretty sure it is not a bandwidth problem.

I have noticed a problem in the console that when one call is connected and
stable this keeps scrolling over and over.

Any ideas as to the cause of the audio problems with G729?
