Need working Kamailio 4.3 configuration for a pass-through proxy with RTP relay. The pass-through SIP proxy will forward all SIP messages (including REGISTER, SUBSCRIBE, NOTIFY, OPTIONS, etc.) and also passes all RTP traffic through RTPProxy. We are using Debian 8 with the standard packaged Kamailio and RTPProxy versions. Standard sanity checking and security options (fragmented packet, ddos, etc.) should also be implemented. Allowed domains / routes will be stored in text db files for ease of maintenance / replication. The objective is allows to multiple separate back end Asterisk PBXs to use a single public IP addresses. This is not a load balancing setup.
Similar project to what we are looking to accomplish, just with a far older version of Kamailio: [url removed, login to view]
