we are unable to pass voice traffic through ASA.Right now ASA is not in a network.Call manager is on 3550 switch.And that switch is directly connected to router 3845.We are using 3845 as a gateway.When we place the ASA in a network everything works fine.Except that we cann't able to register 3845 as a gateway.

Please help

What protocol are you using? H.323,MGCP etc?

Where is the gateway with respect to the firewall (outside)?

We are using MGCP,H.323.

Gateway is on the Outside of the firewall.

Then you have to post the configuration or at least the firewall logs (for denies). Also im assuming the IP telephony setup is completely provided by Cisco and not any other vendor.

Also is the gate H.323 OR MGCP? (You mentioned both).
