Could any one help me for the below BCP plan.
We are several small remote sites connecting to Core Datacenter via WAN MPLS link. All sites local cisco phones are registered in the call manager in Core DC. All remote sites having seperare PRI lines for outbound calls. My question if the local PRI circuit went down, then is it possible to re-route the remote site PRI traffic via WAN MPLS. So the PRI down remote site PRI traffic should go via Core DC site PRI line. I'm not an expert in networking. Need your idea, re-route config (both source and destination end) for doing this BCP plan.
