[Serusers] What's the point of domains?

Hi guys, just a quick question. This is the only 'listen' in my ser.cfg: listen=10.0.100.12 When I add a user like so: serctl add nick(a)foo.bar password nick(a)domain.tld and dial 'nick' or 'sip:nick@10.0.100.12' on a softphone, the call connects and SER's debug messages show that this is being dialled: sip:nick@10.0.100.12 If I try dialing sip:nick@foo.bar a 404 is returned. If the domain that's specified when adding a user isn't actually used in the user's SIP address, what is the point of the domain? Thanks for clearing this up for me, -- Nick e: nick.hoffman(a)altcall.com p: +61 7 5591 3588 f: +61 7 5591 6588 If you receive this email by mistake, please notify us and do not make any use of the email.
