Unity VM Port usage between Server and IP Handsets

Hello,

Our aim is to install our Cisco CallManager Cluster (4.3) and Unity Voice-Mail Server (4.1) behind a Firewall.

Can somebody please tell me if there are other ports I need to enable to establish communication between our 7941 and 7961 Handsets and the Unity Server.

I have confirmed that the RTP UDP Ports 22800-32767 will be needed.

Will I also need to allow the DCOM range of ports to allow access to the Media Master. I know you can decrease the default DCOM range from 1024-65535 on Unity but are the DCOM ports needed between IP Handsets and Unity?

I got this information from the following link:-

http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/unity40/usg/ex/usg001.pdf

I know that Skinny will be required between CallManager and Unity but is this the case between Unity and Handsets?

Any help is appreciated.

Thanks.

Re: Unity VM Port usage between Server and IP Handsets

Unity port settings :

TCP Port Protocol/Service

25 SMTP

53 DNS

80 HTTP

135 MS-RPC

139 NETBIOS-SESSION

389 LDAP

443 HTTP/SSL

445 MICROSOFT-DS

636 LDAP/SSL

691 SMTP/LSA

1433 MS-SQL-S

3268 LDAP

3269 LDAP/SSL

3372 MSDTC

3389 WTS

Dynamic

RPC-DCOM

With the exception of RPC-DCOM, all the protocols and services use a static port.Therefore, the only obstacle to applying a TCP/IP filter is restricting RPC-DCOM to a known port range.
