appending the number just gives me a fast busy.
Mike,
a) is out because the cheaper cisco sccp phones don't have two way speaker phone
b) is what I have, and are trying to get to work. see my previous email about the sip trunk. I don't know what to do to make unity go into the greeting for the user who was called.
c) I'd like to, but I just switched voice mail for all my users, and I don't want to endure the nightmare of switching again. that's my long term goal.

I have my eyes on the Linksys/Sipura 941, ( SIP ), but the core problem is that you can't use SIP phones with CCM. I have a SIP trunk between asterisk and ccm. I can route calls back and forth, I just can't get the call to send to vm if no answer on the asterisk side.

Hi guys,
I want to leave messages on our unity box. I have already converted a couple 7940s to SIP, but I can't give them out to our users because I don't want to have to deal with two voicemail systems.
we have licenses for all our users on unity as is. we're about to buy a bunch more 7940s, but I don't want to cause they're expensive. I'd rather buy a cheaper SIP phone and have it rollover to the unity vm.

support for it. Check the voip-info.org wiki for instructions on
switching the firmware.
Hopefully that will take a step out of the plan -- you could
completely ditch your Cisco system :)
