Cause code on AS5350 gateway

When I sent the VoIP call to AS5350(IOS12.4), I always got "Disconnect Cause=1" if the T1/E1 circuit is down. So that the VoIP softswitch got "unallocated number" which is wrong.

I tried cause-code legacy but it does't help. Any advice would be appreciated.

Re: Cause code on AS5350 gateway

Well, the thing is that from the as5350 perspective, once a DP is down, all the numbers that have destination-pattern in there become unreachable, hence unallocated, or unknown to the gateway.

You can try setting a voip DP with less preference, and non existent session target. The cause code will change then.
