Chiacomo:
Not looking for full integration (have documentation)...just want to send VM-emails to our local users via the Exchange Server. Currently I send them to our off site server, and then that gets relayed to our Exchange Server.
The Altigen server in on the Domain, and I have the user name 'Altigen' listed as an Exchange User...but will add him as Exchange Admin also.
Thanks for the feedback...I'll let you know how this works out!
