Without <no digit collect kpml>, I was getting interdigit timeouts. It may be possible to clean up that behavior by refining the dialplan definition.

I was going to mention that, but your email signature Chat button doesn't work.
Just kidding. Kudos to Kent for the quick thinking.
But why did you turn off KPML?

The issue was related to the overlay (VXLAN), that I use in our lab environment. The overhead of around 50 bytes caused the UDP packet to fragment, and it was not handled well. The solution was to switch the phones from UDP to TCP at the voice register pool level.

This behavior sounds as though the phone thinks it’s registered to the CME, but isn’t..
What are the outputs of these commands?
show voice register pool all brief
show voice register global
show voice register pool <pool tag>
Also, take a packet capture from the CME if you can to see if any SIP packets are making it to the router. It could also be a binding problem on the interface.

Have you tried it with tcp on that dial peer? I know it sounds stupid, but never know these days…..

I am configuring CME 12.5 with SIP phones. However, when I dial from the phone, I see nothing on the router from either dial-peer or ccsip traces. When I dial any of the numbers such as +13145552002, the SIP phone just sits there and eventually gives you reorder.
