[Asterisk-Users] Question on SIP Domains and registration

[Barry Flanagan]

Hello,

I have a situation where I need to differentiate between registrations 
by users where there might be clashes on the left hand side (username) 
portion of the SIP From URI. (for a multi-domain virtual hosting system)

It seems that only the username portion is used for SIP authentication, 
and this means that I have clashes.

I need to find a way that asterisk can differentiate between 
user at domain1.com and user at domain2.com

Does anyone have any idea? Asterisk is being used as the PSTN gateway, 
where all registrations take place on OpenSER.

Thanks.
