Configuring
Your Firewall To Allow Your Phone To Connect.
We recommend that before you
begin this configuration you check that your Firewall is in fact
blocking the phone’s communication by turning your Firewall completely
off and then making a test call – just to confirm that when your
Firewall is off you can call without a problem.
Please note: If you
experience a situation where voice will not travel in one direction (you
can not hear the called party or they can not hear you) then this is
definitely a firewall problem and you should configure your firewall as
set out below.
Note: Both software Firewalls (eg
“ZoneAlarm”) and any Firewall in your router or ADSL modem will
need to be configured. Also insure that if you have Windows “XP” that
you have XP’s firewall turned OFF (found under Advanced Properties for
your Local Area Connection).
If your firewall allows you
to open incoming IP Blocks then open the following:
210.52.67.0 - 210.52.67.255
64.77.238.209, 64.77.227.177, and 64.77.234.219
This may be all you need to do. Please try a test
call at this point.
If calls are still restricted
then please open up all the following ports:
6000 & 6001: UDP
1719 & 1710 & 2000 UDP
1721 & 1720 & 1730 TCP
20000-39999 TCP (for Conference
Calling)
UDP 10000 AND UP : VOICE STREAM
(Insure you open all ports above 10000 so the voice
stream can get through)
For Advanced Users:
