STUN - Port Question

[james_tech]

Hi all,

I have a quick question please, I have a number of locations with DECT devices and I am going to do all the Firewall rules required to make them work properly but I have forgotten if each DECT will need different ports or if using the same port would be fine as they are in different locations.

Example:

London - 5065 : 14000 - 14019
Birmingham - 5065 : 14000 - 14019

OR

London - 5065 : 14000 - 14019
Birmingham - 5066: 14019 - 14039

Hope this makes sense

I always make the ports ranges different for each location, just makes things easier to understand

You can have the same ranges as long as they are in different locations, but make sure you check our guides limitations section https://www.3cx.com/sip-phones/ for the specific devices you are using, as they are not always 20 ports for the RTP for DECT devices.

Thanks - thought so. I have checked documentation, and it says 12 minimum so assigning 20 will not cause any issues?

This will not cause any issue no. Simply also make sure the ports are open and forwarded to the Dect device's IP address on the remote side firewall (phones side), SIP ports are TCP and UDP and the RTP port range is UDP only.
