hi i had the same problem Hi So you mean instead of having rpid=12345678 have it read rpid=12345678(a)domain.com Also I looked at my outgoing message and it doesnt seem to show the Remote-party header in tghe outgoing message as Jan mentioned, I am using xlite to test this one, is your cli working with xlite. The xlite is calling via cisco-gw to mobile phone Iqbal ------------------------------- i solved it in such a way set the rpid to 123456789 at sip.com and the append_hf to append_rpid_hf("<sip:", ">;party=calling;id-type=subscriber;screen=yes"); hope solves your probelm raid -- +++ GMX - die erste Adresse für Mail, Message, More +++ 10 GB Mailbox, 100 FreeSMS http://www.gmx.net/de/go/topmail
