[asterisk-users] Softphone RTP Session Start-up Delay

[Kutman.DK at forces.gc.ca]

Thanks for the reply.  I actually found the problem by inserting print statements in the code and checking which operations took the most time.  I found that one line was taking a long time to run.  The line was the following
 
RTPManager.addtarget(destAddress)
 
After googling this for a while, I found a solution on a JMF site which recommended a minor change in the way that the destAddress is obtained.  After making this change the delay was removed.
 
Thanks,
 
Denis

 here because we are actually specifying the IP Address of the Asterisk server, but I am willing to try anything to fix this problem.  The two user pc's are setup on workgroups, so I do not believe that there is a domain available that can be entered in the hosts file.  Could the DNS still be the issue?  If not, would anyone be able to suggest any other possible problems that may be causing this delay. 


It wasn't the same magnitude (more like 4 seconds for me), but I had an issue where the default eyeBeam (the commercial version of X-Lite) install was imposing a delay when a call first came in while it attempted to contact a non-existent STUN server.  When I removed the STUN server setting, call setup was immediate. 

Might be worth looking at.  Have you done a trace on the PC where the softphone is running (without a filter) to see what network packets are flying at the time the call setup happens?
