[asterisk-users] Asterisk linphone call dropping by itself

[Matteo Fortini]

hi all, please help... I am calling in the simplest way among two 
linphone clients connected to one asterisk server... the call ends on 
one side without any sign of problem, while on the other side it stays 
connected.
I checked the SIP dialogue and at some point the server sends a BYE 
message to one party
I have no timeout set, though the duration of a call is always around 20s.
the two linphones register with a name which is defined as dynamic in 
sip.conf
the call terminates on the caller's side, while the callee is still 
connected, and I have to force the termination on that side.
I'm using asterisk 1.8.0 and linphone 3.99

I really don't know how to investigate further... a capture on sip ports 
just shows that on the 25th ack packet the other side answers with a BYE 
instead of with an OK SDP packet.

TIA,
Matteo
