I need to know how to achieve redundancy using FXO ports on our routers. We have two 3745 routers each with one PRI off of our DS3 from our telco provider, however we have had two occassions in the last month where we've been down completely, no inbound or outbound calls.
We have two 4-port FXO cards and 8 POTS lines in a hunt group which we just havent gotten around to configuring. My question is how do we go about this. What needs to be configured on the routers and what needs to be configured in CM? Any help or direction is greatly appreciated.
