CME 9.1 Provisioning Phone Numbers with Telephone Company

[jdixonak]

The company I work for is currently using Cisco CME 9.1 and recently provisioned 10 of our current phone numbers to a new account for testing. The problem I am having is our existing VOIP phones cannot call out to the 10 numbers we re-provisioned. The numbers work because I can call them with my mobile phone. I believe there is a setting in our current environment that says we have certain phone numbers available to use and so when we try and call one of 10 provisioned numbers it tries internally and never resolves to a phone and then the call fails.

I guess the real question is, is there a setting that assigns SIP phone numbers to the Cisco CME environment? I cannot see anything in the config (show run) that is obvious.

It’s not clear what exactly you have done. What do you mean by “provisioned 10 of our current phone numbers to a new account for testing”? Have you configured those 10 numbers on another CME? If so you’ll need to create dial peer configuration to connect the two CMEs with each other to pass calls in-between them.

Thank you for your response. Let me try and clarify.

We have a pool of phone numbers from one of our telephone providers that we use to assign employees in our CME 9.1 environment. We are testing Zoom for conferencing and so we took 10 phone numbers from our pool of numbers and ported (I think I said re-provisioned) them to Zoom. We were able to configure our Polycoms with those 10 numbers and can make and receive phone calls.

The problem we are having is calling Polycoms from our CME VOIP phones, the call fails. It’s like the CME environment thinks the 10 ported numbers are internal so it never tries to go outside the environment?

So, in short, our CME Environment can make and receive calls to any phone number except for the 10 phone numbers we ported to Zoom. The Zoom environment can make and receive calls to any phone number.

As they now are external numbers that reside in a different system you’ll need to create a dial peer to route the calls.

Thank you.

Convert them to DID’s

[Roger Kallberg]

The OP did AFAIK not give any information on how they have their directory number, so how does this advice fit. What difference would it make to have the directory numbers in DID format?
