Re: [SR-Users] How to encode domain in username for Asterisk REGISTER forwarding (was: How to configure Kamailio + Asterisk (on same server) to route between several disjoint networks?)

[Klaus Darilion]

AFAIK Asterisk supports multiple domains, but it seems that is not used 
for registration.

The above is the non-encoding version. What is the best way to modify it
to do a domain encoding in the username? Or, if a better solution
exists, what is it?


It should work this way:
  $uac_req(furi)="sip:" + $au + "_" + $fd + "@" + $var(rip) + ":5060";
  $uac_req(turi)="sip:" + $au + "_" + $td + "@" + $var(rip) + ":5060";

Be aware that $fd/$td can contain an optional port (depends on what the 
client sends and if you want to accept not only "domain.com" but also 
"domain.com:5060"). So you may need to use one of the transformations to 
URI-escape the domain part.

Of course in the incoming part you have to restore the original URI 
before lookup() the user.
