Bogdan,<div>Thanks for this! This confirms my belief. Hopefully the static userpart will meet the carrier's need. If it doesn't, would it be complicated to preserve the original userpart?</div><div><br></div><div>Thanks for your help!</div>

<tt>Hi Brett,<br>
<br>
1) a SIP URI without username is perfect valid.<br>
<br>
2) as Contact URI is just for IP routing purposes, a username part
is totally useless.<br>
<br>
3) preserving the username may "leak" topo info (you never know
what is the username content).<br>
<br>
4) see the simple attached patch to force a static dummy username.<br>
<br>

<div>I noticed that when invoking topology_hiding from the dialog
module that the contact header is rewritten without a userpart
in the URI. I've had some carriers complain about the lack of a
userpart. What is the reasoning for removing the userpart of the
URI and is there any way to safely add it back without breaking
in-dialog requests?</div>
