[asterisk-users] Jitter only affecting meetme - and echo testing

[Danny Nicholas]

Perhaps your answer is in this document?

http://downloads.asterisk.org/pub/telephony/asterisk/releases/ChangeLog-1.8.
6.0

 

I'm a 1.4 hardliner myself.

1 - Version: 1.8.4.1 (could this be my issue??)

2 - I began building/testing 1.8 prior to 10.0 being released (pretty much
when 1.8.4.1 was released).  As 10 is still in beta, I'm more concerned with
using it than 1.8.... as I've worked out all issues with the build, except
the jitter and these boxes are destined for production use.

 

Thanks!

1.       What version of 1.8 (known issues with some branches)

2.       Why not 10.0?

Greetings List!

 

I'm currently rolling out a new deployment of Asterisk 1.8 to replace
existing 1.2 servers...and have run into an issue which could use your
assistance!

 

For testing I have trunked (iax2) two of the servers - one running 1.8 and
the other at 1.2.  Calls placed from SIP --> SIP sound fantastic and crystal
clear.  However, when I place a echo test call (*43) from 1.8 to 1.2 the
result is a pulsing echo and garbled audio.  The same result is found when
dialing into a meetme conference being held on 1.2 from the 1.8 server.

 

I know that the jitter buffer has gone through quite a bit of work since 1.2
but my results at this point seem to indicate 1.8 is actually worse than
1.2.  

I've also trunked together two 1.8 boxes (physical locations are in
different countries), to rule out if 1.2 was somehow causing the extra
jitter.  My results were identical - echo testing/meetme from 1.8 to 1.8
resulted in the same audio issues.

 

The new servers are in the same locations as our production units, using the
same networks/etc... so I expected identical results between them, not for
1.8 to be substantially worse.

 

Any recommendations?  Has anyone else experienced a similar issue and if so,
perhaps you could share your experience.

 

Thanks!
