I am currently in the process of setting up an asterisk system in my home. I have a TDM 400P card with 2 FXS and 2 FX0 ports.
My local POTS provider, Iowa Telecom, has a brain dead system. I get the 10 digit caller id info with incoming calls, but if I try to redial, it chokes because it needs to have the 1+ in front of the 10 digit number.
I have found that I can setup a calling plan that will strip off numbers, but I want one that I can add a 1 to an numbers that are 10 digit that are sent to asterisk. What do I need to do?
