[asterisk-users] Question on Aastra phones and Astrisk

[Curt Shaffer]

I wanted to add what we have both seen on traffic captures. 

You see Caller 1's RTP stream. Call 2 comes in and you see the creation of
its RTP stream. After Call 2 is put on hold the RTP stream from Caller 1
disappears without a trace never to return and this is when the one way
audio is happening.

And I also wanted to add that I am running 1.4.0 firmware for this phone.

Thanks again!

I'm the friend mentioned here.

I am using the Aastra 480i CT. It is SIP to my PBX and IAX termination from
the PBX to my provider. My issue has a slight twist to it but the same
result. For instance his is always where as mine is frequent but not always.
After I got to finally see it first hand today, I had to start over from
Caller 1 5 times to get it to happen again.

Caller 1 calls in and Person A answers. Caller 2 calls in and Person B
answers. Person B puts caller 2 on hold and audio drops on Caller 1. So
Person A can hear caller 1 but caller 1 cannot hear Person A.

This happens more often when Call 1 is on the handset and Call 2 is on the
portable or vis a vi, but this is not always the case. It does happen to 1
set only but just less frequent.

I have tried carrierinvite=yes and no but this does not change the issue.
The phones are behind a router but the external IP of the router is on the
same network as the * box. 

Thanks!

Curt

Hi,
       Some odd behaviour here.  A friend and I were talking tonight,
and it seems we have both seen the same problem.   We are both using
aastra phones (I am using 9113is).    We have a connection to and from
providers via SIP and IAX.    When I place a call on the local hold of
the phone, and then pick them back up I can hear them, but they can
not hear me.    However, if I park the call, and then pick it up
again, the audio is fine.
      Tonight I tried placing a call on hold using a Sipura/Linksys
ATA (that is just hitting 'flash', which basically puts the call on
local hold and starts music).    The problem did not manifest itself.

Has anyone else had this issue?  Do you have a fix for it?  It is an
astrisk issue or an aastra issue?
