The change done by registrar server to the Contact URI is not
compliant -- the address has to stay what the UA has set. Otherwise
a lot of multi-line SIP phones won't work.<br>
<br>
The user part of the Contact in the REGISTER generated by uac module
is used to match the local user details. If the user part is changed
then it is not going to be a match when a call comes in with the
modified Contact address in the R-URI.<br>

<div>In my case, the provider change the username part of

<div>in register request: Contact:
<a class="moz-txt-link-rfc2396E" href="sip:DID_NUMBER@IP_ADDRESS:5060"><sip:DID_NUMBER@IP_ADDRESS:5060></a></div>
<div>in reply: Contact:
