[SR-Users] Redirect, maddr, and domain

[Daniel-Constantin Mierla]

IIRC, there was no automatic handling of maddr in request uri, only 
record route module does it (or at least did it) for route headers via 
loose route. The sip rfc discouraged use of maddr:

- http://tools.ietf.org/html/rfc3261#section-19.1.1

But you can handle it in branch route, for your specific case. After 
using get_redirect() and before relaying, set a branch route, inside it 
you can use:

$(ru{uri.maddr}) to get its value and use it as outbound proxy:

$du = "sip:" + $(ru{uri.maddr});

subst_uri() from textops should help removing the parameter.

Cheers,
Daniel
