[asterisk-dev] add feature to register to sip provider with "authuser at domain"

[Denis]

Hello all,

I need to register as a SIP Client at my sip provider with
'authuser="xxxxxxx at provider.domain"'. Currently I have no clue how to
do it with asterisk.
Format for register statment is:
register => [peer?][transport://]user[@domain][:secret[:authuser]]@host[:port][/extension][~expiry]

Is it posssible to add option [@domain] to the authuser, so the
register statement would be:
register => [peer?][transport://]user[@domain][:secret[:authuser[@domain]]]@host[:port][/extension][~expiry]

Or may be there are other ways to solve my problem?

Best regards,
Pi Loyder
