Here are the SIP headers of the INVITE from the peer. Notice the From 
header (names and numbers changed to protect the innocent):

INVITE sip:11235551234 at sip.example.com:5060 SIP/2.0
Via: SIP/2.0/UDP 1.1.1.1:5060;branch=z9hG4bK04B9504f83f2bb01fa4
From: "MY NAME    " <sip:11234445555 at 1.1.1.1.1>;tag=gK0407b07d
To: <sip:11235551234 at sip.example.com>
Call-ID: 1550071232_132036005 at 1.1.1.1
CSeq: 351558 INVITE
Max-Forwards: 70
Allow: INVITE,ACK,CANCEL,BYE,OPTIONS
Accept: application/sdp
Contact: "MY NAME    " <sip:11234445555 at 1.1.1.1:5060>
Remote-Party-ID: "MY NAME    " <sip:11234445555 at 1.1.1.1:5060>;privacy=off
Supported: replaces
Content-Length:   326
Content-Disposition: session; handling=required
Content-Type: application/sdp


The SIP headers that are then passed to the user are as follows:

INVITE sip:11235551234 at 2.2.2.2:5060;transport=UDP SIP/2.0
Record-Route: 
<sip:4.4.4.4;r2=on;lr=on;ftag=42902B8F-5B7C26D10008B7A2-13962700;ngcplb=yes>
Record-Route: 
<sip:127.0.0.1;r2=on;lr=on;ftag=42902B8F-5B7C26D10008B7A2-13962700;ngcplb=yes>
Via: SIP/2.0/UDP 
4.4.4.4;branch=z9hG4bK784a.888030fec8faa1a23800660657515737.0
Via: SIP/2.0/UDP 
127.0.0.1:5080;received=127.0.0.1;branch=z9hG4bKF0rzjabv;rport=5080
From: <sip:11234445555 at 4.4.4.4>;tag=42902B8F-5B7C26D10008B7A2-13962700
To: <sip:11235551234 at 4.4.4.4>
CSeq: 10 INVITE
Call-ID: 124565839_134054997 at 67.231.1.154_b2b-1
Max-Forwards: 69
Allow: INVITE,ACK,CANCEL,BYE,OPTIONS
Accept: application/sdp
Supported: replaces
P-Asserted-Identity: <sip:11235551234 at 4.4.4.4>
Content-Type: application/sdp
Content-Length: 361
Contact: 
<sip:ngcp-lb at 4.4.4.4:5060;ngcpct=7369703a3132372e302e302e313a35303830>


Note that the "MY NAME" name has been removed from the From header. This 
is the caller id name information that can be displayed on the user's 
phone. That information is also in other headers, not of which are 
passed on either.

Suggestions?
