[OpenSIPS-Users] mediaproxy latching

[Edwin]

I got a problem with mediaproxy (mediarelay). The media relay is in front of
our Teles C4 platform.

After an INVITE from client to opensips to Teles (C4) the first teles
audiocodes starts sending RTP (0.3 seconds) from 31.168.32.35, after this
our mediarelay starts sending audio to 31.168.32.35. Nothing strange here.
This Teles gateway can not forward the call and the call is hunted to the
second gateway, 31.168.32.36. After this the first 183 SDP is sent from
teles (C4) to opensips with 31.168.32.36 in the connection information.
Teles states it is correct to sent audio from the first audiocodes, then
hunt to the second and only put the second ip in the SDP packet.

Problem is mediaproxy/mediarelay starts sending audio to the first
audiocodes and does not alter the stream because ip and port are the same in
all sip packets.

Question is, can I change the behavior of de mediaproxy (latching only to
client side) or, if not, how can I prove to Teles the behavior of C4 in
incorrect?
