[SR-Users] Duplicate values in SDP

[VOIP Tests]

Hello,

Can some one let me know the reason that there are these duplicate values
in the SDP ( o, c, m, nortpproxy)? Our server was working with kamailio and
asterisk on the same machine and had no problem. When we separated kamailio
and asterisk on different servers and added the dispatcher module I see
this error because of which there is not audio from an incoming PSTN call.
