Problem!! TCP connection timeouts...

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all!

I am using the GNU GK v2.2.2 and it is used in a satellite network (a system 
which ESA is involved)...

The GK is configured in H.225 Routed Mode.

When I try to make a call from a user located at Terrestrial Network and a 
user located at Satellite Network the TCP connection (H.225) is not 
established because the [SYN, ACK] received from the Satellite user terminal 
arrives too late. The GK sends a Release Complete.

Due to the high delay of connecion establishment of this Satellite Network 
(more than 6 seconds) the VoIP call CANNOT BE ESTABLISHED!!

I have increased the SignalTimeout an Setuptimeout values with not success 
at all. It happens always the same: The GK sends a [SYN] TCP message. After 
3 seconds, it retries to send a second [SYN] and after 3 more seconds the GK 
interprehets that the H.225 cannot be established and it is finally dropped 
with a Release Complete H.225 message. After these ReleaseCompelte messages, 
it arrives the [SYN,ACK] messages from Satellite Connections. Too Late!!

The fact is that we want to either increase the number of TCP [SYN] retries 
of the GNU GK or increase the 3 seconds timeout between [SYN] tries.

Does anybody have an idea in order to do it?

Thanks

Victor
