Hello
all,
I have a problem
with some user-agents (namely Grandstream and Cisco ATA 18X). My SIP provider
provides a UPDATE instead of a re-INVITE, because the mentioned user-agents
support the UPDATE method. However, SER/RTPProxy doesn't know how to handle this
UPDATE request, and forwards the request to the user-agent. Result:
one-way-voice.
Does someone know
how to solve this. I solved it for now by replacing the UPDATE in the request,
so the SIP provider doesn't see that my user-agents supports the UPDATE
method.
Thanks in
advance,
Regards / Met vriendelijke
groet,
