My users want to use usernames in their phones e-mail-type style. Like username@domain.

With FS it works ok. The only problem I’ve faced - it’s when you route this call via proxy like OpenSIPS or Kamailio. Actual problem, when you bridge user@proxy, your URI becomes like

username@domain@proxy.

So, This RURI is dropped by proxy with reason «cannot be parsed» or so. Actually, they are right,

Is there any way of avoid to use two @ in URI?
