We have deployed VoIP 2 years ago. It is CCME 3.1 based on 2811 router and 34 phones - 7912G.

Now we want to expand the number of phones, so what solution we need to minimize migration tasks and keep old (34 ) phones in use?

I see this solving:

CISCO3845-CCME/K9 3845 Voice Bundle w/ PVDM2-64,FL-CCME-240,SP Serv,64F/256D

What interface card I need to channelize this voice gateway with our PBX (E1)?

Will it support 7912G phones and what new phones of the same class we need to buy ?

Hi, you need VWIC-MFT-1E1 or VWIC2-MFT-1E1/T1 to connect the PBX.

Suggest you upgrade to like 12.4(11)XJ4 that is CME 4.1, does many more things and does them better, in short is a big step ahead. It will support any phone model you want including the latest 79x2 and 79x5, even if the CLI doesn't mention them (that is coming out now).

Hope this helps, please rate post if it does!
