Jim, and all:

Thanks for the response.

If I can repeat what you are saying:  you don't have to define the multiple 
lines in sip.conf?

For comparison, with my current esi setup, we have 10 outgoing lines.  If one 
line is busy, then the service just rolls to the next number.  This is set up 
with the phone service.

That doesn't have to done with outgoing sip lines?  Does the dialstatus have to 
be checked when a user dials out?

I understand the incoming lines - we will have a block of DID numbers, and I 
can check those and send to appropriate extensions.

Thanks all for helping to clarify.  I have gotten a couple of users who haven't 
been able to call out, and wasn't sure if I wasn't "rolling over" the sip lines 
properly.

Best,

Eddie Mikell

I think it is typical to have some limited number of outbound channels to your 
SIP provider. You send all calls, up to your limit, to the same place. The 
phone numbers your provider gave you are used to route inbound calls to your 
asterisk box. You will typically have some limited number of inbound channels. 
All people could call the same number, again controlled by the number of 
channels your provider allows. A reason to have multiple inbound (DID) numbers 
is so you can route each number to a specific dialplan extension. You might 
route one number to the CEO of the company and the other to a voice tree that 
allows the caller to specify the person's extension they want to talk with.
