Hotline Server

IN UDP 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 outgoing so if you want to
disable in bound on a firewall it would work fine)

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.

One additional UDP and one TCP port in the range of 1 to 30000
must be mapped. Ports 6802 and 6803 are suggested. These ports must be mapped in your firewall, then set in the Net2Phone client
as follows:
1) Click
on Net2Phone's "Menu" button.
2) Select "Preferences".
3) Click on the "Network" tab.
4) Enter 6802 for the Client TCP Port.
5) Enter 6803 for the Client UDP Port.

The last 2 UDP outbound ports are usually set in pairs. 1024 - 1025,
1026 - 1027, etc... Most users never have to set these lower two ports.
They are dynamically assigned if you leave the lower two boxes set to
0's on the 'paltalk port settings' tab. Outbound ports are usually not an issue but are listed here for network
users who may need to manually configure for a proxy or NAT server or
other hardware device.

This Mapping is needed to hear the audio from the incoming party, outgoing
audio would work without it.
** According to phonefree the ports you need open are:
8000 TCP For Server access
1034 UDP Voice in/out
1035 TCP Voice in/out
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!).
