Change default EFXS to DID

Question

Hi Cisco techs,
I wrote a discussion about 3 weeks ago but had no replies. Perhaps I didn't word it correctly via 
https://supportforums.cisco.com/discussion/12353726/did-and-channels-sh-voice-port-summary
I am aware that EFXS is created automatically for ephones.
I would like to change the automatic EFXS connection that a phone uses to connect to too DID instead.
Is this possible?
Let me explain.
sh voice port summary output is below
cme_router#sh voice port summary

The session gets dial tone but doesn't connect.
Does DID use a channel similar to EFXS does?
Thanks again in advance

Answer 1

The solution is so simple and straightforward that I feel like a fool for asking.
Only when you already know it. There's no documentation that really states it. It's one of those long time Mac behaviors a person just needs to learn.
