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

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,
