Attended Transfer doesn't connect

[Dath]

Hello,

I am having trouble with the Attended Transfer function in the 3CXPhone for Windows App.

When trying to call the extension i want to transfer the call to, my side of the incoming call doesn't get muted and no call is going out to the destination extension.
Am i doing something wrong or is there something I have to configure to make this work?

• 3CX Version, Professional Perpetual 16.0.8.9
• Server OS, Debian 9
• Is the 3CX Server Hosted and where? VM hosted on our servers
• IP Phone Make/Model/Firmware Phone for Windows 16.3.0.220
• Provisioning Method: Local / VPN / STUN / SBC Local
• Trunk Provider or Gateway Make/Model Vodafone
• Has the Firewall Checker passed: YES
• Are custom Phone Templates being used: NO

Thanks in advance.

Hi @Dath,

Can you describe the exact steps you follow to see if I can reproduce this behaviour?

I call from my mobile phone, take the call on the VoIP Phone, 3CX App shows the call, I press Attended Transfer, Contacts open, i choose an extension number from the contact list or enter an extension number (tried both) and hit enter or double click, dial tone sounds from the VoiP Phone and two beeps on my mobile phone and I'm still in the call as before and no ring goes to the chosen extension.
To end the call i have to first end the call to the extension though, and then i can end the call to my mobile phone
