We recently reconfigured our network with 2 VLANS for our new VoIP system. We installed the voicemail server on the voice VLAN, VLAN 2, and we are unable to telnet to IMAP on the internal Exchange server for integrated messaging from this voicemail server. In addition, we are unable to access the web from machines on VLAN 2. We appear to have inter-VLAN routing setup correctly, though I am not sure.
We are able to ping everything from every network just fine. Even a tracert to www.google.com
works from VLAN 2, however, the web page is never returned to the browser following the DNS request. If we put the voicemail server onto VLAN 1, it can telnet the IMAP on the Exchange server fine.
