PBX - 5400
MAS/UCA Server
NO MBG
NO Teleworker
UCA Client External.
Those who have followed my posts know I scored a major victory by getting the UCA Softphone to work outside of my office yesterday. That's the good part.
The part I want to refine is closing unnecessary ports on my external facing firewall between the Internet and the two publicly facing IP addresses on my 5400 and expansion chassis.
In order for the softphone to work, I have to open ALL ports to my PBX and expansion chassis.
On Page 13 of the Engineering Guide for the UCA with no MBG, it states that the following ports need to be open:
3998-3999 TCP
5060 UDP
6004-6261 UDP
6604-7039 UDP
5004-5070 UDP
6800-6802 UDP
50098-50508 UDP
5566 TCP
5567 UDP
5570 TCP
4000 TCP
4000 TCP
44000 TCP
69 TCP
20001 TCP
I've opened these ports up and more, but the softphone doesn't work unless I open up all the ports. So I have to assume this list is incomplete or not providing necessary details.
Anyone have a list of ports for a UCA softphone and a 5000 Series?
