[SIPForum-discussion] FORMAT FOR A SIPS URI

[OSWALDO TORRES]

Hello, my ISP send me that INVITE.
I have a doubt in the URI.
Received: 
INVITE sip:6795;phone-context=local at ntlpba.mx;user=phone;behindnat SIP/2.0
From: <sip:8182213405;phone-context=national at ntlpba.mx;user=phone>;tag=80315
To: <sip:6795;phone-context=local at ntlpba.mx;user=phone>



Is correct, that format sip:user;uri-parameters=parameter-value at domain;uri-parameters=parameter-value;behindnat SIP/2.0

O it must be:


sip:user at domain;uri-parameters=parameter-value;uri-parameters=parameter-value;behindnat SIP/2.0


Basically, my doubt is after the user must have the domain or not ?
