Registering CME phones over a routed network

Unanswered Question
Sep 12th, 2008

Hi,

CME uses mac addresses to identify ephones.

However I know it is possible to register e-phones that are not in the same subnet as CME with SCCP.

But I cant recall how its done.

Also I believe it is possible not using auto-registration.

Any ideas ?

Thanks

I have this problem too.

Ok, I think I solved the issue.

I can just add the phone (CIPC in my case) using the mac address of the phone as that is the name of the cnf file that the phone is asking for over tftp.

The only restriction is that the mac-address has to be hex and 12 digits long.

(CME does not do a reverse arp to validate that the phone is on the same subnet)

However, when I register CIPC with CM I can give any string and it does not have to be in the range A-F.
