I am using 4.0.4-017289 ecs-centos5
I have setup flowroute ITSP but experiencing about a 1 min delay until a call goes through. Tech support from flowroute pointed to a wrong field in the SIP INVITE that is generated by sipX. The field in question is the "Route" field that is not supposed to be there according to RFC 3261 (section 16.12.1). It is that route field that is causing the delay according to tech support. Below is a trace of a SIP INVITE showing the Route field. INVITE sip:[email protected];user=phone SIP/2.0 Call-ID: YmVhYzE4YjRmYmFmYjMxZjc3ODcyOWNmZGM3OWU2OTc..0 CSeq: 2 INVITE From: "sipxbridge" <sip:[email protected]>;tag=7096640509074490091 To: <sip:[email protected];user=phone> Via: SIP/2.0/UDP 71.121.31.69:5080;branch=z9hG4bK27860b8d8515fb73c8bed55904b71d19343431 Max-Forwards: 70 User-Agent: sipXecs/4.0.4 sipXecs/sipxbridge (Linux) P-Asserted-Identity: <sip:4087011540> Contact: <sip:[email protected]:5080;transport=udp> Route: <sip:70.167.153.130:5060;transport=udp;lr> Session-Expires: 1800;refresher=uac Allow: INVITE,BYE,ACK,CANCEL,OPTIONS Content-Type: application/sdp Proxy-Authorization: Digest username="69061003",realm="sip.flowroute.com",nonce="4b8e195c0001626fee9d7ef 3c3d7ca7c35f6bc6e6bf90319",uri="sip:[email protected];user=phone ",response="ccb527bf7bce7a28e044a58d666b0e68",qop=auth,cnonce="xyz",nc=00000 001 Content-Length: 313 Is there a way to fix this??? Any help is greatly appreciated. Cheers, Marcello
