Samsung Officeserv Ports for QOS

I have an Samsung OfficeServ phone system.

I am trying to narrow down the ports I need to apply for QOS.  All handsets in the Main Admin are connected to the Officeserv and outgoing calls are sent via our ADSL gateway.  There are also a handfull of handsets at remote locations that use the internet to make calls via the OfficeServ

The phone tech reports "6000, 9000, 6100,  1024 30000-30031 and 40000,40027 are used for the ip phones.".  I am guessing that not all of these are used for calls, with some being port fwds so that he can access the OfficeServ device remotely

I've uploaded a drawing showing the logic, any guidance would be appreciated

One option is to use a sniffer like Wireshark to see what ports are being used.

Please upload the document.

I can confirm that you need all those ports. also 5060 and 5061 is also important.

Outgoing calls start with 30000 next call 30001 next call 30002 until it reaches 30031 then it starts over with 30000 same with 40000 range.
To save yourself a lot of issues and time  create a rule and open all ports from the pbx and block remote management port (5090) from internet.

You should be fine, just make sure port 6000 (udp) is open over your VPN port 6000 is used by the IP phones to connect to your PBX and that both sides of the link is reachable (ping).
