-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, no, dunno that. i think this is because my provider knows somehow that the call was originated from a foreign voip domain. I'm talking to my colleagues (my provider, hehe) about that message. Oh got now the answere. My provider rejects the call in a sip firewall on our SBC. They cannot use DNS (cause of techincal reasons), so they can't resolve the dns-name in the c field of INVITE's SDP message: ------------------------------------------------------------------------ INVITE sip:044180002850@sip01.voice.ewetel.de SIP/2.0 Via: SIP/2.0/UDP sip0.en.ewetel.de;rport;branch=z9hG4bKtQUm3j5m8javF Max-Forwards: 69 From: "032223930016" <sip:101@sip0.en.ewetel.de>;tag=rF71mQ9etU9HQ To: <sip:044180002850@sip01.voice.ewetel.de> Call-ID: 5a571254-41ca-122a-ff9c-005056947ed9 CSeq: 80214586 INVITE Contact: <sip:mod_sofia@sip0.en.ewetel.de:5060> User-Agent: FreeSWITCH(mod_sofia) Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, PRACK, MESSAGE, SUBSCRIBE, NOTIFY, REFER, UPDATE, REGISTER, INFO, PUBLISH Supported: 100rel, precondition Content-Type: application/sdp Content-Disposition: session Content-Length: 258 Remote-Party-ID: "032223930016" <sip:101@sip0.en.ewetel.de>;party=calling;screen=yes;privacy=off v=0 o=FreeSWITCH 4760289687929138191 1084810514790632154 IN IP4 212.6.123.118 s=FreeSWITCH c=IN IP4 sip0.en.ewetel.de <----- This seems to be the reason why t=0 0 a=sendrecv m=audio 16388 RTP/AVP 0 0 101 a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 ------------------------------------------------------------------------ so there r two way to solve this: either my colleagues change their production environment to use DNS or freeswitch replaces sip0.en.ewetel.de with the correspondig IP address. Is there a way in freeswitch to do this ? regards Helmut Brian West schrieb:

You know any reason why your provider might reply like that?
