[Freeswitch-users] Audio Connection Delay with SCA

[Sean Devoy]

Hi,

 

I finally got Shared Call Appearance working to 4 NAT connected phones!!!!!

 

Now the users say when they answer that line, they must wait a second or so
to start talking (no big deal), but they all claim it takes nearly 5 seconds
to be able to hear the caller.  They answer the standard "Thank You for
calling XYZ, how can I help you today" which the caller DOES HEAR, but they
cannot hear his response for the first 5 seconds and ALWAYS have to ask them
to repeat it.

 

In the logs, I see what I believe is them picking up extension 299:

    2012-06-08 11:44:15.115249 [NOTICE] switch_channel.c:926 New Channel
sofia/external/sip:299 at 69.251.170.6:5063 .

And then the RPT finally connecting:

   2012-06-08 11:44:20.665094 [DEBUG] sofia_glue.c:3248 AUDIO RTP
[sofia/external/sip:299 at 69.251.170.6:5064] 10.10.40.185 port 23500 ->
69.251.170.6 port 16498 codec: 0 ms: 20

 

Note the 5.5 second delay!  Granted there are 100+ lines between those if
you want to see them, I will post them.

After that audio is fine.

 

Any thoughts would be appreciated.

Sean
