Voip (SIP) switch

[geoffrey mendelson]

I am looking for advice or pointers to web sites with advice (in  
English) about setting up a SIP switch and would appreciate any help.

What I have is several SIP accounts which I want to integrate into one  
soft phone. The soft phone will run on MacOS ( I already have it) and  
the switch will run on UBUNTU, I have a choice of a system running  
9.04 and another running 9.10.

It's very simple. My computer will make outgoing connections to the  
various SIP servers, none will attempt to connect to mine. Once  
registered, calls, probably one a day between all of them, will be all  
routed to the soft phone.

Dialing out will be more complicated. calls begining with 1 or 0 will  
go out on one connection, I can use prefixes such as 9 or 8, etc to  
call on the other connections.

While I assume that Asterisk is the software of choice, it does not  
matter. In fact, something simple would be prefered over something  
complicated with more features I won't use.

Thanks in advance,

Geoff.
