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,
