Using loopback address for return packets

jogillis

We have setup our voip dial-peers to use the loopback address with the 'voice-class source" command. Thats ok for one direction. Now how do we setup the receiving end to use its loopback address. Is there some command to put on the dial-peer pots entry to force the use of the loopback address on the return packets.

PS In case you have not noticed I know next to nothing about voice, so please forgive if this is an easy, straight forward question.

These commands on your loopback interface will source all H323 traffic from the loopback. You do not need the dial-peer voice-class command.

h323-gateway voip interface

h323-gateway voip bind srcaddr x.x.x.x

HTH.

There is no h323 gateway explisitly defined anywhere in the config.

For H323, you would use the above config. For SIP, there are equivalent commands.

Thanks for the replies. I do not know enough to know whether I am using H.323 or sip. Will try the suggestions.

Thanks
