Putting Media Streams on Hold

Hi Community,

Maybe you can help sorting out this issue, hopefully

On the access we have some IP-PBX’s like Lync that when they put a call on Hold it is done according to the RFC 3264 (8.4 Putting a Unicast Media Stream on Hold) with the method sendonly

/recvonly. Unfortunately on the core we are not supporting this method but the older one from rfc2543 (B.5 Putting Media Streams on Hold

) which puts in the SDP the "c" destination addresses to 0.0.0.0.

Is there any way around to let’s say convert from one Leg (access) RFC3264 to rfc2543 for the (core).
