Options would appear to be:
a) use cheaper SCCP phones like 7905/7912 and stay
with CCM
b) put an asterisk box up and configure a SIP trunk
between CCM and Asterisk - I have done this and it works although there used to
be a bug with the CCM box not tearing down the RTP at the end of the call - it
appeared to rely on receiving an ICMP "port not reachable" from the other end -
this could probably be fixed with the appropriate rtptimeouts ?
You would add new users on Asterisk using SIP
phones and have a mixed system.
c) ditch the CCM and go 100% Asterisk
You might consider (b) in the short/medium with a
road-map towards (c)

SIP phones to Cisco Unity via CCM4.0SIP Trunk
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.

Cisco Unity via CCM 4.0SIP Trunk
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.

You
can run a SIP image on a 7940. [EMAIL PROTECTED] has pretty good
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
:)
