I have route list, with two route groups and a gateway in each group. They gateways are H.323 (3825) with E1 connections on both. When the call goes to the first gateway and its E1 interfaces are down I'm receiving cause code 1 unallocated number. I have to change the service parameter for re-routing in the CallManager to true if I want to have re-routing.
This solution isn't good enough for me because I'm receiving the same message when the PSTN is up also. So I have excess re-routing.
I also tried to issue the command "no dial-peer outbound status-check pots" but it doesn't help me. The output from the "debug isdn all" is empty and the cause code is again 1.
I also tried with different dial-peer setups with trungroups because I have 3xE1 and with ports only and the result is also negative.
