Help dissecting a failed call

[dandenson]

The call came in and spawned 2 calls in the logs. The first call is the obvious problem. I don't know what caused it though. The second call is kind of expected, it sees the phones busy (from whatever went wrong on the first call) and so dumps it to voicemail.

I just don't know why the first call failed. In that failure, the phones began to ring and then continued to ring after the call had failed.

the first and second calls are from a single call placed by the caller.

Also note that the phones didn't reregister after this call, so if there were connectivity issues they weren't enough to have the phones reregister.

too many lines to put in the post, so here's pastebin of the logs (sanitized)

Hello @dandenson

From the provided logs i can see 2 calls coming from the provider as there are 2 different Call Id's.
They seem to arrive at the same time which could cause the phones to appear as busy if one call started ringing before the other.
We may need to check the time with milliseconds to see exactly what happened as the calls seem to hit the PBX in the same second.
