MessageYou need to make sure that ACK is forwarded regardless of whether loose routing or not is used by the UAC. If I remember correctly, Sipura will work even when you don't have loose_route handling, so that means that you maybe have a processing error for ACKs not being handled by loose route. Try to follow the path of ACKs in an ONsip.org config file as a reference for how ACKs should be handled. g-)

hi all,ter around

we use ser with many differents handests, ata and softphones.

with some of them (sipura and Zyxel) the call finished after around 20/30 seconds. The terminator send us a 200 OK when communication start, but with these UAc, ser doesn't send back an ACK to the termination.

Any idea of how to solve that problem?

Thanks,

Olivier
