Ports to be open in Firewall for voice

murali.rao · ‎07-01-2005

Hi,

We have a IPCC setup with CCM 4.0(2a) Sr2a integrated with IPCC express 3.5(2).

PSTN calls are routed through the WAN to the IPCC setup.

All the remote PSTN gateways(Cisco routers with T1) are registered as MGCP on the CCM.

Due to security reasons we are introducing a firewall in the Local LAN so that all the traffic from WAN got through this firewall.

What are the ports I need to open on the firewall to allow the voice traffic(for IPCC express,CCM & RTP ...)

Regds
