Fast Busy Tone after Disconnecting call

[ParaR]

Dear Members,

I have a problem with a Yealink device.
When a caller disconnects the call i hear a fast busy tone. The line is not disconnecting automaticly.
This wasn't a issue before i updated the 3CX platform to 16.0.4

For this issue i cant find any settings in the Yealink phone device or on the performing SIP Trunk.
Is there any settings in the 3CX where this can be changed ?

Thanks in advance,

Pra

Hi,

We need some more information like

- Yealink model?
- Firmware version?
- Is it automatically provisioned via PnP or manually?
- In Local / STUN / SBC mode?
- Are you using the default templates or custom?

Please reset your phone first

Then wait for it to appear in the 3CX "Phones" section.

Tick the phone from the list, and Assign it to an extension

Press Ok and wait for the phone to auto-provision.

Once it is ready and registered, make a test call and tell us if it behaves correctly now.
