[Linphone-users] SIP not working in high latency networks

[Станислав]

Hello!
So the problem is that linphone can't setup a call in high latency 
networks - for example  if working via SAT link (can have over 1800 ms 
delay very easy)

From my testing its stopping working at around 650ms of delay.

Here is log what happening:
10.0.20.15 is notebook with hlinphone
10.0.10.5 is asterisk 1.6 server

Linphone just spams invites (but it should wait ~500 ms first time...up 
to t1*64 right ? ) and eventualy it sends BYE to asterisk because 
linphone thinks that there is connection problem. At  same time linphone 
itself shows that call is established...


Is there any way to increase wait timeout to atleast 2 seconds ?
help me please ! :(
