ephone dn not working

Hi there,

This is an issue on cme. I have an ephone-dn. When it is assigned to a button, it receives calls but cannot make calls. A 'debu ephon det mac' is attached. Can some explain the debugs?

Thanks in advance.

Re: ephone dn not working

Is it possible you can paste the relevant parts of your configuration? Namely the configuration of your ephone-dn's and the ephones themselves.

Re: ephone dn not working

Did you try to uninstall and reinstall the IP Communicator? The config looks OK to me. If this all of a sudden stopped working, then it could be an issue with the CIPC, not really too sure.

I am using the Communicator to test the DN. I got the same results as with the physical phone. So it cannot be a problem on the phone. When another DN is assigned, the phone is working fine.

Re: ephone dn not working

Are you getting a dial tone? What response do you get upon callout (busy signal, network message, etc)?

Re: ephone dn not working

No tone is heard. It just hangs there.

Re: ephone dn not working

Not quite sure what could be causing the issue. Try removing the ephone-dn from the configuration, and then replacing and applying it to the ephone. You can also do a "show dial-peer voice summary" and see if you see a default dial peer with the destination pattern of 5580. I'm really just grasping at straws here. Also, one last thing, is this number on a PRI or is it a POTS line?

Yes, the dial-peer is there on port 50/0/10.

It is on a 7912 phone directly connected to the cme.

Re: ephone dn not working

Did you try to remove/replace the ephone-dn from the config and then try to reapply it to the ephone?
