ITSP SIP; CUBE 14.7 on ISR 8300 17.12.4 to CUCM 14.0.1

Hello all,
My team is deploying an ISR 8300 on 17.12.4 running CUBE 14.7 to connect to ITSP SIP (Masergy) for in-bound / out-bound E.164 calling. Our internal UC Cluster is version 14.0.1. We have E.164 DID TNs associated to 5-digit extensions for off-net callers to reach on-net user's VoIP phones.

At the moment, we are utilizing Masergy's "Test DID" (4633030297) to validate our configurations and their service.
Placing a call from a cell-phone to the Test DID yields ringing in cell earpiece till user picks up, followed by silence.
The VoIP phone will also ring, but answering yields silence on the desk phone as well. Once the call is answered at the VoIP phone, the CUBE router shows it as a live SIP call.

Here is a rough topology:

CUBE_Topology.png

We have an ISR 4000 at the ISP boundary which is configured with NAT, PAT, a subinterface for the private-IP network on which the CUBE router resides, and Access Control.

Attached is the output of [debug voice ccapi {inout}; {error}] and [debug voice dialpeer {inout}; {error}] in "DEBUG_SIPGW" text file.
The below code-block is a trimmed output of the debug when calling the test DID from a cell-phone:

Finally, attached is a PDF with screen shots of the SIP trunk and Profile between the internal UC and ISR8000 CUBE RTR.

I would appreciate any assistance and will be happy to provide any additional details.

Here is the ladder diagram of the call based on the logs you shared. One question: did the call actually connect on both sides? Does it show that the call duration started on both ends? I don't see a full exchange of messages for a successful call in the log.

Why don't you terminate the ITSP link on the CUBE? Why do you introduce a NAT device between the ITSP and the CUBE?

As you're using NAT you'll need to do way more with you SIP profiles than you currently do. Below should be a good stating point.

Hello Philip,

As the disconnect cause for the call is 86 which means:

Call Having the Requested Call Identity Has Been Cleared.
Indicates that the network has received a call resume request containing a call identity information
element indicating a suspended call that has in the meantime been cleared while suspended.

It looks you are missing some configuration in your CUBE/ISP router as suggested by @Roger Kallberg 

Thanks.

If the phones are ringing and the call is picked up, it suggests that the SIP signaling is good. However, it sounds like you may not be allowing the range of RTP ports from your ITSP's media servers. Do you have an ACL configured on your boundary router allowing this?

I had a similar issue when I upgraded a customer cube router from an ISR G2 to a 4K. The default RTP port ranges are different on the different platforms. Here is what I had to add to 4K to make it play nice with Centurylink.
