Brian, Thanks for your reply. When I tried leaving them set to auto I got the following when I called pa call 1234: 2007-04-13 11:30:23 [DEBUG] sofia.c:72 sofia_event_callback() event [nua_i_state] status [0][INVITE sent] session: sofia /82.22.75.210/1234@conference.freeswitch.org 2007-04-13 11:30:23 [DEBUG] sofia.c:846 sofia_handle_sip_i_state() Channel sofia/82.22.75.210/1234@conference.freeswitch .org entering state [calling] 2007-04-13 11:30:23 [DEBUG] sofia.c:72 sofia_event_callback() event [nua_r_invite] status [503][DNS Error] session: sofi a/82.22.75.210/1234@conference.freeswitch.org 2007-04-13 11:30:23 [DEBUG] sofia.c:72 sofia_event_callback() event [nua_i_state] status [503][DNS Error] session: sofia /82.22.75.210/1234@conference.freeswitch.org 2007-04-13 11:30:23 [DEBUG] sofia.c:846 sofia_handle_sip_i_state() Channel sofia/82.22.75.210/1234@conference.freeswitch .org entering state [terminated] So I figured the DNS error was caused by Sofia using my machine IP instead of external IP. But when I changed the settings to my external IP I notice that Sofia gives an error when binding to the IP and port (so it obviously needs the local IP). Does the problem therefore appear to be a NAT issue? I currently forward all ports, but it looks like the problem may be caused by the address being translated rather than the ports being blocked? Do I have to make any configuration changes to setup NAT traversal? I also get this during initialisation: 2007-04-13 11:30:15 [NOTICE] switch_loadable_module.c:128 switch_loadable_module_process() Adding Endpoint 'sofia' Total of 0 name servers found from win32 registry. Is this to be expected?

I am behind a NAT, but all ports are forwarded to me. I hit the play button in VS 2005 and FreeSSWITCH appeared to start with no errors. I entered "pa call 1234" at the command prompt. I received no audible indication that a call was being made, should I have done? The call appeared not to connect because of a NO ANSWER, should it have connected?
