The title may be somewhat misleading, but I am running into an issue with our CUBE. We own an entire NXX, originally on PRIs and slowly moving it over to ATT IP Flex. Some of our numbers from our NXX have been ported to our corporate phone system separate from us. Calls across the PRI gateways go through no issue, but calls across the CUBE to ISTP timeout after around 20 seconds and the provider is getting a Q.850;cause=102 as the reason for disconnect.
When the call originally goes through, I can hear the recorded greeting and after about 20 seconds I get a busy signal and then am disconnected. From looking at the traces on the CUBE it seems as if it goes through and then the CUBE is trying to send INVITEs to each of the Call Manager servers in the middle of the call, which receives 404s as it is no longer built on the Call Manager side. I can then see the reason code that the provider sent me as well. Below is a call flow example and the current applicable CUBE config. What am I missing here?
Call Example: 2055556789 dials 92055551515, call routes and hear the recording greeting, call gets busy signal after 20 seconds and drops after about 30 second total duration.
