I have an alcatel 4039 deskphone and i wonder if there is any possibilites to use a mini jambox (a brand) as a conference phone.
I tried to put an aux cable to the jack input in the 4039 device, but there would only be sound then. I would like to have the microphone working too.
If there are no ways this will work, are there any other opperunities to use as conference phone on a 4039 device?
thank you for answer in forward
