Solved No dial tone when connecting calls internally

[Vettel]

Hi,

I am using a 3CX with Yealink T41S phones and a Gigaset N870 Dect base station.
When I answer a call on a Yealink phone and connect it to a Gigaset handset or another Yealink phone, I get no dial tone.
When I answer a call on a Gigaset handset and connect it to another handset or Yealink phone, I get dial tone.
So it seems that the Yealink phone is the cause.
Do you have any ideas?

Hi there.
So when you say:

When I answer a call on a Yealink phone and connect it to a Gigaset handset or another Yealink phone, I get no dial tone.

So you refer to the dial tone while waiting for the call to be picked up from the other end?

 

[Vettel]

Exactly. Internally, the user doesn`t hear a dial tone when waiting.

This dial tone is played by the device itself and not the Phonesystem, so you should look into the logs of the devices and maybe see with the support team of the vendor

Ok thanks. Maybe there is a setting at yealink phone? Do you know what this setting might be called?

If you are on V18, you can check the options below, which are in the Users >> extensions that are affected >> Options tab >> Troubleshooting section :

Hi, I use V20. Where can I find this option?

 

[OlegR_3CX]

Ok, as mentioned it was in the case of using V18, so for V20, those options are hidden from the interface, so you don't need to worry about them.

 

[Vettel]

Ok thanks. Is there such a setting on the Yealink phone?

 

[OlegR_3CX]

This is not Yealink phone settings but 3CX.
See the issue you have with the vendor and see what they will advise.

Hi, the Thread is solved.

Have a nice day
