[Serusers] Different Domains in one SER.

Hello List. I have a question for the list. I want to know if is possible to serve two domains in a single SER machine. The idea is have two domains and have for each domain different authentication methods, different exec( ) command calls, and even maybe different billing model. Is possible to implement this?, if so, the best method to separete the "profiles" is by a if (uri=="mydomain1.com") else if (uri="mydomain2.com") or somethign like that?. For example is possible in a sigle machine have something like this. ********************************************************* * SER SIP PROXY SERVER * * IP : 192.168.1.10 * ********************************************************* Profile 1. Profile 2 Users Registered with Users Registered with Domain Domain sip1.mydomain.com sip2.mydomain.com Prefix = 555 Prefix = 444 This domain have This domain have authentication 1 authentication 2 authorization 1 authorization 2 billing 1 billing 2 exec 1 exec 2 Any help is welcome. Best Regards. Ricardo Martinez
