I'm wanting to let several companies share one of my SER boxes. These companies have overlapping extensions for their phones (the registrations are unique, though). Is there something I could do, perhaps with avp's, to denote which organization a particular call should be subject to? For example: Company 1 Exten: 1234 SIP user: alice Exten: 1235 SIP user: bob Company 2 Exten: 1234 SIP user: eve Exten: 2345 SIP user: frank If bob calls alice by dialing 1234, is there a way to look up the organization, and rewrite the uri to go to the correct place so that alice doesn't accidentally get sent to eve? I would like to do this without static rules in the ser.cfg so that I can just set the organization by adding an avp when I create the users. I am also using CPL to handle dialplan type of issues already. Anyway, thanks for any help!
