Polycom Soundpoint IP 335

What ports need to be opened on the firewall for this phone to work. A new contractor has brought this phone with him and would like it to be accessilble. So it powers up and looks good, however it can't dial out. Assuming the port is blocked. Would there be any other configuration needed besides the port in the firewall?


Again right now I need the port numbers to open up for this phone, dont know what else would be needed to make this phone work.

Also, the Line Status info shows


Line 1: xxx-xxx-xxxx (not registered) (not registered)


I assume because it can't connect. dont know if there is some configuration needed.

I am unsure what SOftware you are currently running but the UCS 4.0.1 Admin Guide or newer that can be found => here <= shows the ports in the Table 11-3: Ports used by Polycom Phones.
