[Serusers] newbie - Handle incoming calls?

[Tim Pushor]

Hi All,

I'm new to all this stuff, so apologize if these are dumb questions.

I have an account with a local/ld voip provider. They provide me a SIP 
connection to/from the pstn. I have this working with sjphone and xten. 
I also have ser running (very basically) and handling/routing calls for 
local softphones registering with it.

I really want to be able to receive incoming pstn calls and route them 
internally.

Here's where my ignorance comes in. The sjphone and xten register at the 
vendors registrar as sip:nnnn at vendor.com. I havn't seen an example or 
read anything how I could configure ser to do that.

Also, the SIP line is authenticated. How do I tell ser to use a set of 
credentials when sending/receiving SIP messages to my vendor?

Thanks!
Tim
