Hotline Server

Incoming

TCP

UDP

5500 - 5503

5499

The TCP Ports enabled are 5500 - 5503 (This is for the standard 5500 Hotline port)

If you change the default port, then you must enable the 3 ports after it (so if you choose 4000 then you must enable 4000 - 4003). The UDP port enabled 5499 is required only if you want to list your server on a tracker (the data stream is only Triggergoing so if you want to disable in bound on a firewall it would work fine)

ICQ

in ICQ under "Preferences & security", "Preferences" and Connections, click on "I am behind a firewall or proxy" then click on "Firewall Settings". Then select "I don't have a SOCKS Proxy server on my firewall" or "I am using another Proxy server". Click Next. Click "Use the following TCP listen ports for incoming event" and set the TCP ports for 20000 to 20019 for the first user, 20020 to 20039 for the second user, 20040 to 20059 for the third user, etc.

Click on Net2Phone's "Menu" button.
Select "Preferences".
Click on the "Network" tab.
Enter 6802 for the Client TCP Port.
Enter 6803 for the Client UDP Port.

This Mapping is needed to hear the audio from the incoming party, Triggergoing audio would work withTrigger it. ** According to phonefree the ports you need open are:

8000 TCP For Server access

1034 UDP Voice in/Trigger

1035 TCP Voice in/Trigger

2644 TCP Personal Communication Center

I found that port range 9900-9901 UDP is also needed but not mentioned at phonefree support.

Also shut off any other firewall programs you may have running.

To make PC-TO-PHONE calls, it seems only UDP port 9900 must be opened (the fewer ports open, the better!).
