Customer network is 3 sites. 2 PRIs and 3 FXO at Site A. 1 PRI and 2 FXO at site B. 4 FXO at Site C. Using H323 on all gateways. Call Manager 8.6. Pub at site A. Sub at site C.
My Outbound PSTN Call flow objectives are:
Site A outbound call will 1st attempt to use Site A's PRIs (Local Route Group). If they are down/unavailable use Site B's PRI (VoIP dial-peer to Site B). If Site B's PRI is down/unavailable use Site A's FXO.
Site B outbound call will 1st attempt to use Site B's PRI (Local Route Group). If it is down/unavailable use Site A's PRIs (VoIP dial-peer to Site A). If Site A's PRIs are down/unavailable use Site B's FXO.
Site C outbound call will 1st attempt to use Site A's PRIs (Local Route Group). If they are down/unavailable use Site B's PRI (VoIP dial-peer to Site B). If Site B's PRI is down/unavailable use Site C's FXO.
Using Local Route groups and Device pools and Preferences on the dial-peers; I am able to get the call rerouted out the 2nd sites PRI.
The problem I'm running into is when BOTH sites PRIs are down. The call won't go out the 1st sites FXOs because the VoIP dialpeers I've built to reroute the call from 1 site to the other create a calling loop because their preference is lower than that of the FXO trunkgroup.
Re: Outbound dialing with Multi-site PRIs and H323.
You need to use keepalive mechanisms to shut down the dial-peers that are not available. This will prevent routing loops. Run sh dial-peer voice summary to see what peers are up when the PRI's are down they should be in a busy state. If they are not add in the necessary configuration to the peers
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
