[reSIProcate] SIP Proxy

[Dan Weber]

Currently, I'm looking to implement a small network of about 60 users my 
company.  I'm looking for a sip proxy and registrar that will allow for 
extensibility, so later we could add additional services.  I need 
something capable of building a user login system, that is also capable of 
aliasing names to phone numbers.  If anybody knows of a good one, please 
tell me.

Thanks
Dan
