The ones with 2 earpieces and a mass of about 100 grams invariably (?) do A2DP which transmits stereo at 44100 Hz or 48000 Hz, compressed with the SBC codec. The single-ear ones with a mass of about 20 grams invariably (?) do HSP/HFP, monaural at 8000 Hz, I think uncompressed. That would be your Jabra BT 250v. Some but not all of the music headsets can switch protocols and have call control buttons for HFP; these are advertised as "works with Skype". So the Jabra is capable of doing the HSP protocol, and when the message says the protocol is "not available", the problem is likely not in the headset. Not likely that the headset is broken or has buggy firmware, but just for paranoia, it would be a good data point if the same message were seen with a different headset. I've seen a similar message when I didn't have bluetoothd-service-audio configured to autostart and forgot to start it manually. Do you have the corresponding protocol/profile daemon running? I don't have my laptop handy to look up the name of this daemon but I think it's bluetoothd-service-sco. This is in bluez-utils-3.19 (3.20 is latest; probably came in at 3.16.) Unfortunately that's about the limit of my expertise, since I haven't messed with the HSP/HFP feature of the Motorola HT-820 that I have. James F.
