Caller tree configuration - NEED HELP!

[melozurdo]

Hi,

I need to configure a caller tree and apply in 4 deskphones but not really sue how to do this.
I´ve configured a UA Virtual in Omnivista 8770 with a non DID number and with voicemail type "0" as individual ones.
The caller tree should be picked up after 4 rings and give the option to go to the individual voicemail (pressing 1) or go to a specific extension (pressing 2).

Correct me if I am wrong about the steps / questions:
1. Create UA Virtual number in Ominivista 8770 with immediate forward to voicemail of this UA Virtual number. This is the 4 digit new caller tree number. Let´s call it 4444
2. In all of the deskphones involved, configure "associated set No." to the new 4 digit caller tree number (4444)
3. Create extension voicemail number 4444 with voicemail type "0". Should I create type 32 (callers menu + extension) instead of "0" ?.
4. The option to go to the individual voicemail (pressing 1) or go to a specific extension (pressing 2), should be configured using personal options - greetings - personal greeting - personal?

Please advise. We are using Omnivista 8770 and Voicemail 4635. Thanks.
