ephone dn compared to dial peer

Hello I have a CME gateway router which has previously been configued with ephones and their respective ephone-dn's. That was all working fine.

Now I have migrated my phones (with the same directory numbers) to a CUCM installation. CUCM will still use the CME router as it's PSTN gateway.

As part of the CUCM replacement, I have created dial-peers so that incoming calls to my CME gateway router will be redirected to CUCM.

My question is, should I now delete all those original CME defined ephone-dn's. i.e. will they conflict with and cause problems with my newly created dial-peers for these same directory numbers that now point to CUCM ?

For instance an incoming call arrives at the CME gateway router. It sees an ephone-dn in addition to a dial peer pointing to CUCM. Both are for the same directory number. What happens ?

Thanks for any advice.

I would simply issue "no telephony-service" which will delete all ephone and ephone-dns to make sure you have clear config.

When having ephone-dns in the running config, the calls won't route to CUCM by default.

Change dial-peer hunt scheme to do based on preference:

dial-peer hunt 2

Under telephony-service, change the dn preference:

max-dn 64 preference 9

That way your dial-peers to CUCM will be matched first.  Probably best to just remove the CME config unless you're also trying to do CME as SRST.

Yes, remove the CME config as this router will act only as a gateway now.
