Re: [SR-Users] Kamailio-5.3.3. NAT and RTP not working

HI, Hold on a moment, > 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?
