Hi all, let's say SER receives this invite: INVITE sip:foopbx@ip.com SIP/2.0 Via: ... To: "058633345880101" <058633345880101(a)ip.com> [cut] and assume that there is an entry in the user location table for ''foopbx(a)ip.com" (ie it registered with SER) and assume that entry in userloc has a "Server: Bar 1.0 PBX" value I'm wondering if is possible to do something like that: if (!lookup("location")) { log(1, "User not in user database...\n"); route(whatever); break; }; if(get_server_string_from_userloc() =~ "Bar 1.0 PBX") { take the number from the "To:" header and write it in the request uri. So the forwarded msg will look like: INVITE sip:058633345880101@ip.com SIP/2.0 Via: ... To: "058633345880101" <058633345880101(a)ip.com> [cut] }; thank you very much, I really need your help Ciao FF
