Re: ISR 2821 + CME and Skype for SIP

Vlad,

The local DNs are registering because you don't have no-reg configured under the DNs.

You should have something like this:

ephone-dn 1

number 2112 no-reg primary

If you need an e164 number registered to skype, the easiest way is to add it as a secondary number on the DN you want the calls to that DID to go to.  Something like:

ephone-dn 1

number 2112 secondary 5551231234 no-reg primary

I should mention that certain dial-peers will also have a default behavior of trying to register.  'no-reg' under the peer will disable that.
