It looks like opensips will do exactly what we need and I have a working config below with a few caveats: If the called party hangs up there is no SIP BYE packet sent from our ITSP to us. I assume there is still something that I need to change in the forwarded packets. Does anyone have any pointers? If the caller hangs up it is fine. I've tried removing the g711 codecs but this results in a different packet size and the Content-Length isn't recalculated automatically. Is there an easy way to do this? And is it a problem leaving a blank line in it's place? Probably other issues that I don't even know about due to my very very rusty knowledge of SIP.
At this stage I have only tried outbound calls via our ITSP. For reference opensips is only listening on the routers internal IP (192.168.52.1). All comments welcome, including if there is a better way of doing this. debug=3 log_stderror=no log_facility=LOG_LOCAL0 fork=yes children=4 /* uncomment the following lines to enable debugging */ #debug=6 fork=no log_stderror=yes disable_tcp=yes #disable_dns_blacklist=no #dns_try_ipv6=yes auto_aliases=no port=5060 listen=udp:192.168.52.1:5060 ####### Modules Section ######## #set module path mpath="/usr/lib/opensips/modules/" loadmodule "rr.so" loadmodule "tm.so" loadmodule "uac.so" loadmodule "xlog.so" loadmodule "textops.so" # ----------------- setting module-specific parameters --------------- # ----- uac params ----- modparam("uac", "credential", "<userid>:sip.pennytel.com:<password>") modparam("uac","from_restore_mode","auto") ####### Routing Logic ######## # main request routing logic route{ t_on_failure("1"); if ( is_method("INVITE") ) { xlog("Calling: $oU\n"); } if ( has_body("application/sdp") ) { # the following will not cause the Content-Length to be recaulculated #replace_all("a=rtpmap:.
