[SR-Users] SIP INVITE and To Header

I have a general question maybe somebody can help me out with. We have a new SIP Trunk setup with a provider. The SIP Trunk has a username of 'jane' and it handles 400 DIDs. When the incoming INVITE from the provider comes in, the URI in the Invite is the username of the trunk while the To header actually has the dialed number. As long as I can remember I have always seen the Invite as having the same URI as the To Header in the initial INVITE but not so here. 18:17:34.786 SIP.STACK MSG INVITE sip:jane@10.5.5.5:5060;transport=UDP SIP/2.0 18:17:34.787 SIP.STACK MSG Via: SIP/2.0/UDP 10.10.10.10:5060;branch=z9hG4bK290hka10e8j11dn7k0k0.1 18:17:34.788 SIP.STACK MSG From: "Test "<sip:9541112222@voip.xxx.net;user=phone>;tag=1574552918-1430345854933- 18:17:34.788 SIP.STACK MSG To: "Customer"<sip:2222222222@voip.xxx.net> I am inclined to believe this is perfectly normal and compliant but let me know what you think.
