Hey Everyone,
I'm having a weird issue with my Fanvil X4U and X3U phones when blind transferring they hang for about 20 seconds saying "transferring" then drop the call and the transfer does not go through. If I try to do an attended transfer the two parties stay on the line and the "Xfer" button to complete the transfer does nothing.
Using the same extension numbers and Internet connection, I'm able to send transfers just fine using the smartphone app or the web client app. Also, the Fanvil phones can receive transfers no problem. I've tried using the PBX delivers audio option no luck with that.
Versions
Latest V16 3CX system running on Amazon EC2
Using 3CX recommended firmware for phones, X3U 1.2.1 and X4U 1.0.5
Any help is greatly appreciated, thanks!
