[Mac-telephony-list] Neebee question

[Dennis Dunbar via List]

Thanks to a couple people on the old Astmaster list I got my iMac  
Asterisk up and running fine.  Now I just tried to use a soft phone  
at a remote location and the Asterisk didn't see it.  I though I  
would just have to put in my IP, configure port 5060 etc.  No go.  I  
have a FQDN going to the IP where the Asterisk is so I tried that no  
go.  I have good service in and out using VBuzzer and t38 out fax  
using Gafachi.  I really wanted to access my VBuzzer from a remote  
soft phone via Asterisk.

What am I missing.

Thank you in advance.
