I have three PRI's running onto my router, with around 500 phone numbers on it. If there is a phone number on the PRI from teh telco but no associated DP on the router, then the call takes up all remaining trunks as it searches for a home.
The fix for this is to make sure that there is a DP for each number and point it to session target ipv4:18.104.22.168
But we have clients that shut down all the time, and with their DP still there and not removed, we run into the same problem.
Is there anyway I can creat one DP that say, if you don't find a better match for any incoming call send it to 22.214.171.124
