Provisioning of DECT base fails

[Mate M.]

I want to evaluate the 3CX cloud pbx.
The phone system has been deployed successfully.
But I'm failing to configure my DECT base Gigaset N670 IP PRO.

• firmware version: V2.36.0 (V2.36.0+build.732061a)

For this I tried the auto-provisioning by adding an FXS/DECT device.
When I copy the provisioning link into the web UI of the DECT base and klick save and then start automatic configuration, I get an error message provisioning failed after a few minutes.
I get the same result, even when I download the XML file from the 3CX provisioning link and upload it by hand into the DEC base.
Can somebody help me to get my DECT base putting into service?

Edit:
Meanwhile, I set the DECT base's firmware back to version V2.23.0 (V2.23.0+build.6aa1ed0), because they say this is the last supported for 3CX (compare: https://teamwork.gigaset.com/gigawiki/display/GPPPO/3CX)

Are you using the 3CX SBC?

No, I'm using the free evaluation subscription of hosted 3CX Standard:


The deployed instance has 3CX Version 16.0.6.655,16.0.6.655
And these are the activated services:

Hi @Mate M.

The 3CX SBC is an additional piece of software that you install at the site where the phones are
https://www.3cx.com/docs/3cx-tunnel-session-border-controller/

It helps "bridge" your site to the cloud PBX, and if you read our guide for that model you will notice that it has the limitation of needing the SBC to function, as STUN is not supported (provisioning type).

If you need any further clarifications we will be glad to assist!

A cloud PBX need a SBC on remote site

Ok, thanks for this hint. What does STUN means?

Hi Mate,

If you want to learn more about how 3CX works (including how LAN,STUN,SBC is used) we highly recommend to take our free Academy course. It will teach you all the basics and help you deploy your system quickly and easily.

We are also hosting a 3CX Webinar in about half an hour which will explain about Remote Extensions if you are interested.

Ok, thank you. I thought is was passible to put the DECT base into service by using a PBX provider like 3CX.



I didn't know that a third component (SBC) is needed. Thanks for your help.
