I have installed unity 3.1(3), integrating that to an existing exchange 2000 server. I have installed all the listed patch and the hotfix. I am using sql 2000 server as the ports are more than 32. The problem i am facing is when i hit the pilot voice mail number, I am able to hear the unity welcome greeting. But unity is not playing any voice mail which is in the mailbox. I am able to ring the phone from the unity server. I am able to send and receive mails (not voice mails) via outlook, that narrow downs that my exchange is working fine. <br><br>Senthil Natarajan<br>Network Engineer<br>NEC BNS<br>720 Bay road, Suite 100<br>Redwood city, CA 94063<br>Phone: 650-216-3516<br>
