10.40.10.3 - pcscf in port 4060 (pcscf with NAT
enabled in pcscf.cfg
(!#define WITH_NAT) and configured rtpproxy)
10.40.10.12 - icscf in port 4070
10.40.10.5 - scscf in port 4080
10.40.10.30 - hss
So i assume you are using the examples provided in the ims folder of
kamailio repo right? Isn't it using RTPEngine and not RTPProxy? Or have you
modified the P-CSCF configuration to work with RTPProxy?
Best regards,
Supreeth
