What ports do I need to open in my firewall?

Problem:


What ports on your firewall need to be open.



Solution:


If you have a firewall, you must give the Phone Adapter rights to access certain Internet ports, including:


69-69 UDP


5060-5063
UDP


8000-8003

10,000-20,000
UDP


Depending of the configuration/device used, different ports may be accessed. It's recommended that you put the device IP on the router DMZ.
