Voip problems

We are having problems with our Voip phone conversations only being one sided. This is while connected to our firepass and only firepass. The user of the voip phone can speak, but can't hear the person on the other end. Tunred off Napt and went with virtual network and still didn't help.
  • I guess you mean you have 2 ssl-vpn clients trying to talk to each other by voip, right?

     

    after turned off Napt you may also...

     

    if you use split tunneling, you may try adding ip-pool (client subnet) to LAN address space.

     

    otherwise try "force all traffic to tunnel"

     

    but if the user on the other end is on LAN, you may make sure it has correct routing for ip-pool subnet (i think it is what you called virtual network) via firepass.
  • Thanks for the response! The situation is this: The Voip phone is an SSL client that is trying to connect to IP pbx on our internal LAN. We are using an IP Pool and Napt is turned off. Our core LAN router has the route for the ip pool to use the LAN interface of the firepass as it's next hop. The Firepass has a route in it to use our core router for the network the IP pbx sits on.

     

     

    Now another detail is that the IP pbx and the inside interface of the firepass are on the same network. They really don't need to talk to through a router. Does the Firepass act like any other router that should know about the networks it is directly attached to and not send it the specified gateway (our core router) in the Firepass routing table?
