Transferred call rings on 2 extensions

[DJ Hattingh]

Hi All,

We have a user that has recently upgraded to V20. We currently have an issue when the main phone (ext 2001) transfer a call to an extension (2004), the original phone and the transfer extension rings at the same time.

Below is the setup so far:
- There are no "Ring All" groups configured
- First extension is setup on a Yearlink T28-P. Second extension is a Yearlink T31-P
- We have confirmed that there are no forwarding settings on either the extension on 3CX or on the phone
- Extension 2004 is not configured on more phones than the T31-P



Your assistance in this matter will be greatly appreciated. Please let me know if more info is needed.

Thanks

Hello @DJ Hattingh,

Can you please let us know the provisioning method used to provision the IP phones?
Can you please also check if the option "Ring my Mobile" is enabled and the Mobile configured is the extension?
If you use Web Client, do you get the same results?

Hello @Dimitris_3CX

Provisioning method is STUN (auto provisioned)
Ring my mobile is disabled and no mobile configurations on the extension
The Web client does the same thing.

Hi,

Please note that STUN is not supported, 3CX is designed to be used with SBC as STUN is less reliable.
If you remove the IP phones and try with the Web Client or if you provision the IP phones via SBC. Do you still get the same results?
