I'm trying to configure some VVX400's to work with Aircall.io, our cloud based SIP provider.
I've upgraded the phones to version 184.108.40.2063
I can make and receive calls internally and externally but I can't transfer.
I try to do a consultative transfer using an extension or an external number. The destination phone rings and the audio works fine, but when I complete the transfer, the destination line goes quiet (it doesn't hang up) and the attached screen is what the transferring phone has on it.
The line is paused, what does that mean? And is there a resolution to cleanly making the call transfer and then freeing up the line?
