Unanswered Question

Hi Team,

As we have Overlay ephone-dns with Call waiting with Cisco Unified Call Manager express.

Can we do the same setting in CUCM server with version

OS Version        : UCOS

I need to migrate the phone on CME to CCM server and required the same settings on the phone.

Please suggest.



I have this problem too.

You'll need to do one of two things:

1) Create a hnt group - put the phones in a  'line group', set it to 'broadcast', and add that to a 'hunt list'. Add a 'hunt list' for the pilot number.

2) Alternatively add the same DN to all the phones, and set the max calls/busy trigger appropriately for that shared line.

Thanks Aaron for the quick reply!!

I am new to this environment if you could provide about where do we find these options in call manager GUI would be helpful.

In the phone configuration window, I am not seeng Hunt group option listed.

That would be too easy :-)

The options are under Call ROuting/Route\Hunt/ - three options for line group, hunt list, and hunt pilot. Do them in that order!

Hi Aaron,

I have configured the above settings and its working fine but facing one issue with Call Transfer.

I have assigned one extension number 9XXX to all 4 phones and configured the same extension as pilot number as well because user need it that way. But when PhoneA want to transfer call to the same EXT#9XXX, it wont work.

Will you please suggest if it requires extra setting fro Call Transfer function to work?

Why do you need to configure the user extensions the same as the pilot number??? That's just confusing.

I presume becuase you have assigned the same number to everything, that you had to put the pilot number in a different partition?

Basically you need to ensure that the CSS assigned to the users lines has the partition containing the pilot 9xxx number above the one containing the user extensions, so that it goes to those as a tie breaker. Having a pilot of 9000, and users of 9001,9002 etc would mean it just works normally.
