When the call is set up, each side informs the other of the ports that it is prepared to receive media on. The numbers on either end can be different. So sipXecs will tell Vitelity a port pair from the ones you configure on your system to send to for each call. Most default firewall rules will allow any packets out, so you shouldn't need to set anything for the ports Vitelity wants to receive on; you do need to set your firewall to forward all the media ports configured on your sipXecs to the sipXecs server. _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
