My current gateway REGISTER packet has a certain FROM header, as shown below: REGISTER sip:66.33.147.150;transport=udp SIP/2.0 Via: SIP/2.0/UDP 54.174.255.168:5080;rport;branch=z9hG4bKKQayX8pZ5yctp Max-Forwards: 70 From: <sip:+1404XXXXXXX@66.33.147.150>;tag=FQag8jSNpac9c To: <sip:+1404XXXXXXX@66.33.147.150> Call-ID: d3cd81b1-c9e2-4401-8126-f4e545e3ebce CSeq: 69955649 REGISTER Contact: <sip:gw+switch2voip.us@54.174.255.168:5080;transport=udp;gw=switch2voip.us> . . . What do I set/change in my gateway configuration to add a character string "1404XXXXXXX" to the FROM header? As shown in red below: REGISTER sip:66.33.147.150;transport=udp SIP/2.0 Via: SIP/2.0/UDP 54.174.255.168:5080;rport;branch=z9hG4bKKQayX8pZ5yctp Max-Forwards: 70 From: "1404XXXXXXX" <sip:+1404XXXXXXX@66.33.147.150>;tag=FQag8jSNpac9c To: <sip:+1404XXXXXXX@66.33.147.150> Call-ID: d3cd81b1-c9e2-4401-8126-f4e545e3ebce CSeq: 69955649 REGISTER Contact: <sip:gw+switch2voip.us@54.174.255.168:5080;transport=udp;gw=switch2voip.us> . . . I am already setting the following values (in my gateway definition): <param name="from-user" value="1404XXXXXXX"/> <param name="caller-id-in-from" value="true"/> Thanks, George
