CME and 7912 IP Phone question

Hi All

Is it possible for a 7912G IP Phone to have a Primary Number and also a shared number with multiple phones.  I want each phone to have its own extension, but multiple phones to ring for a specific number.

Thanks

Hey there,

I'll try and fill in for Paolo for a moment (+5 "P")

Shared-Line Overlays

Dual-line ephone-dns can also use overlays. The configuration parameters are the same as for single-line ephone-dns, except that the huntstop channel command must be used to keep calls from hunting to the ephone-dn's second channel.

The primary ephone-dn in a shared-line overlay set should be unique to the phone to guarantee that the phone has a line available for outgoing calls, and to ensure that the phone user can obtain dial-tone even when there are no idle lines available in the rest of the shared-line overlay set. Use a unique ephone-dn to provide for a unique calling party identity on outbound calls made by the phone so that the called user can see which specific phone is calling.

Shared-line Overlaid Ephone-dns: Example

The following is an example of a unique ephone-dn as the primary dn in a simple shared-line overlay configuration. The no huntstop command is configured for all the ephone-dns except ephone-dn 12, the last one in the overlay set. Because the ephone-dns are dual-line dns, the huntstop-channel command is also configured to ensure that the second channel remains free for outgoing calls and for conferencing.

ephone-dn 1 dual-line

number 101

huntstop-channel

!

ephone-dn 2 dual-line

number 102

huntstop-channel

!

ephone-dn 10 dual-line

number 201

no huntstop

huntstop-channel

!

ephone-dn 11 dual-line

number 201

no huntstop

huntstop-channel

!

ephone-dn 12 dual-line

number 201

huntstop-channel

!The following ephone configuration includes (unique) ephone-dn 1 as the primary line in a shared-line overlay

ephone 1

mac-address 1111.1111.1111

button 1o1,10,11,12

!

!The next ephone configuration includes (unique) ephone-dn 2 as the primary line in another shared-line overlay

!

ephone 2

mac-address 2222.2222.2222

button 1o2,10,11,12

What have you added and how? Must post your config.

Also remember to type restart under ephone after making changes.
