IP Communicator via easyvpn to proxy phone - no audio
A remote laptop user connecting via easyvpn connection to an ASA 5510 8.2(5) cant communicate with a proxy phone user connecting through the same ASA. They both come up with IP addresses in the same subnet (the vpn user 10.85.80.50-254 from a DHCP server and the proxy phone shows as the ASA internal interface of the ASA 10.85.80.22) The calls do setup and show as connected but there is no audio between them. Both the IP Communicator user and the proxy phone user can call internal phones and dial out the voice gateway without issue.The VPN connected user cannot ping the ASA internal interface but LAN users can.
