Cisco Call manager 7.2 through ASA firewall

[smith606306]

Hi,

We have a part of our building that we have sold to another company. We still have to provide them with some resources until they can install their own network. We have a 6500 switch there and we are going to implement a ASA in between and lock down most communication. One of the resources required are  Cisco IP phones. 

Does anyone know which ports etc are required to be opened to allow communication between these phones and  Call manager and other IP phones on the site?

Any help would be appreciated

Hi Andrew

The attached document may assist:

A lot depends on topology etc, and the handset registration protocol you are using (SIP vs SCCP).

Hope this helps.
