now that the send function issue got resolved, i tried core forward function. core cookbook tells: forward Forward the SIP request to the given destination in stateless mode. This has the format of [proto:]host[:port]. Host can be an IP or hostname; supported protocols are UDP, TCP and TLS. (For TLS, you need to compile the TLS support into core). If proto or port are not specified, NAPTR and SRV lookups will be used to determine them (if possible). If destination parameter is missing, the forward will be done based on RURI. Example of usage: forward("10.0.0.10:5060"); #or forward(); i then went i tried forward("tcp:192.98.102.20:5070"); but got errors from that line: Apr 7 13:52:10 siika /usr/sbin/sip-proxy[22923]: : <core> [proxy.c:278]: ERROR: mk_proxy: could not resolve hostname: "tcp:192.98.102.20:5070" Apr 7 13:52:10 siika /usr/sbin/sip-proxy[22923]: ERROR: <core> [route.c:1214]: fixing failed (code=-478) at cfg:/etc/sip-proxy/sip-proxy.cfg:1584 i also tried with forward_tcp("192.98.102.20:5070"); but it didn't help either: Apr 7 13:54:24 siika /usr/sbin/sip-proxy[23056]: : <core> [proxy.c:278]: ERROR: mk_proxy: could not resolve hostname: "192.98.102.20:5070" Apr 7 13:54:24 siika /usr/sbin/sip-proxy[23056]: ERROR: <core> [route.c:1214]: fixing failed (code=-478) at cfg:/etc/sip-proxy/sip-proxy.cfg:1584 how should core cookbook be fixed this time? -- juha _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
