I have a cisco lab, and i have been expanding my voice section lately. the newest addition is my IAD 2430-24FXS. i originally had my FXS ports terminating on my 1801 CME router, but wanted to migrate away for expansion purposes. can people chime in with best practices when using two gateways in regards to COR? how do i pass the class of restriction or ensure it is being conformed to when leaving the IAD and entering the CME? FYI: i am using COR at this time to seperate line usage by groups of people within my house. i have a sip trunk with viatalk a magicjack using an fxo port and a verizon ports line over fios using an fxo port all on the 1801 cme router. Thanks in advance!
