[Serusers] SER IP PBX for multiple clients

If you are already using multiple contexts within asterisk, then your 
already half way there, the problem is if you stick in SER, bcause then  
your phones are not registered in asterisk, hence all fall into the same 
context in sip.conf, which means they all  will hit  one context in 
extensions.conf, hence you should look into that.

I am not sure if you can do the 101/102 extension thing in asterisk, 
since aliases will be bound to a contact, whereas in asterisk the 
context is also part of the dialing plan.

DID can be done, as can forking and directing to voicemail on no answer.
