I am currently using a bluetooth speakerphone for my doorbell project to answer SIP calls. Unfortunately Bluetooth connection is not so reliable. I prefer a wired speakerphone. Can anyone suggest a speakerphone (speaker with built-in mic) that is using 3.5mm phone jack that I can plug in to my tablet? Something similar to normal earphone with mic like this…
…but instead of sound coming out from the tiny earbud, it comes out from a speaker. Most probably it needs additional source of power to boost the sound quality.
Any suggestion? Thanks.
