I want configure 4 FXO Ports on a CME router.The scenario i am using is that my customer has 1 PRI and if that fails then all the outgoing calls should go through FXO ports.Also i don't want any incoming calls to come on those FXO ports.Please let me know what all parameters i need to configure for the same.
The easiest way is you can create several separate outbound POTS dial-peers, one pointing to the PRI (with the default preference 0), the other one with preference 1, 2, 3 etc.. pointing to the FXO ports.
To block incoming call, you can do something like this:
voice translation-rule 100 rule 1 reject /^.*/ !
voice translation-profile BlockCalls translate called 100
