(CUCM SIP->H323) call immediately drops after connecting; Reason: Q.850;cause=86
Call Flow: (used my cell)PSTN caller->VGW1->CUCM->UCCX->Agent xfers to internal operator-> Internal Operator blind xfers to end user-> end user has cfwd all set to his cell phone-> SIP Trunk ->Cube/VGW2 ->H.323 PRI -> PSTN
Call connects for 1 second then drops
If I call the end user directly the call connects fine(Call comes in and exits on VGW2 not VGW1)
I collected debugs on VGW2 (can't share entire debugs - customer info)
VGW2 disconnects the call (Sends BYE to CUCM and Disconnect MSG to Provider)

(See screenshots of Translator X diagram (debugs from VGW2) attached)
In comparing calls
I see a reinvite coming from CUCM (INVITE 105) that swaps out the Operator's PAsserted ID and Contact with my cell info. When that gets passed to the provider it shows plan: uknown/unknown. Not sure if this is the cause.
Could it be a callerID issue where callerID is provided but in an unsupported IE by the provider? A call status did get generated with a call state and no mechanism for recovery thus a drop? See below from provider after disconnect.

ask for any info and I will provide it as best I can.
