Folks,

We have callmanager servers in the voice vlan and we would like to protect then at L3 by using access-lists. Does any have have a template that shows the ports I need opened on the l3 interface (vlan interface) to only allow traffic that should be going into the voice vlan?

Parwal,

Check this link. It shows tcp/udp ports used by CM server. Its pretty straight forward. If its 4.1 CM that you have, there is link inside this link that gets you to ports used by 4.1 CM.

Re: Voice Guru

sankar,

would you have any kind of template that you could send me, it would make my job much easier. Sample config would work as well.

Thanks,

Tarun
