We are planning a new Unity Connection 2.1 deployment in an already running Cisco VoIP ready netwotk.
Our topology is as follows:
- voice equipment (IP Phones, CallManagers...) goes in "voice VLAN".
- network servers (LDAP, Exchange...) go in "servers VLAN".
- finally, there's a "data VLAN" dedicated for PC and so on.
Our Unity Connection 2.1 server will be installed in the "servers VLAN".
The problem is that there are strong inter-VLAN connection restrictions (ACLs, firewalls): only a bunch of designated equipments can reach from one VLAN to another, and only to some specific ports (LDAP, SMTP...)
I would need to know the connection/ports I should allow so that IP Phones and Cisco CallManager can "talk" to Unity Connection flawlessly.
Thanks in advence.
