hi guys,
I have the following scenario. I want to use Asterisk as voicemailserver,
but need an rtp-Proxy because the my phone speaks srtp. I get SIP-Message
from an PBX to openser and RTP Proxy. My question now is, how I can handle
this case or how I can forward from rtpproxy to asterisk? just with
rewritehostport?
Hi Martin, you have repeat exactly the already answered question.
First: RtpProxy doesn't handle SIP signalling so when you say "I get
SIP-Message from an PBX to openser and RTP Proxy" that is incorrect.
Second: Asterisk doesn't handle SRTP and SRTP is end to end, like RTP, so a
RTP proxy can do nothing (think in it as a UDP proxy in fact).
In conclusion: you can speack SRTP with Asterisk since Asterisk doesnt'
support it and you cannot use a RtpProxy as intermediary for that purpose.
