I have a need to setup a server to host the registration for 25-50 lines from a retailer and then act like a sip trunk into the PBX. has anyone attempted this yet?
I have done it a few times. Are you going to want billing ? What service will they be connecting to ?
I was looking at using broadband.com.
I am not worried about billing for now as the lines will be unlimited in the US, and I should be able to block International call.
It should not be a problem. No one out there offers true unlimited. Make sure you have a look at their TOS.
dovid,
do you have an example config?

Are you using a GUI or just the asterisk configuration files ? Also exactly what do you want an example of ?
