Exactly, I will send a debug confirming that once I have access to the router.

Are you saying the dial-peer digit stripping is occurring *after* the voice-port-level voice translation is applied?

My expectation is that the dial-peer should be matched first then apply digit strip and at the exit from the E1 interface translation profile to be applied.
