GrandstreamNetworks GAC2500 IP Android Conference phone

Having used this device in various meetings for more than 2 years now I'd say this device is adequate at best.Using it strictly as a basic SIP phone it's pretty good quality wise.Using it as an audio device attached to a PC (e.g. for a Zoom or Teams meeting) is pretty OK but only if connected with a USB cable, which may not be suitable in all meeting rooms given length constraints of USB cables. Bluetooth is terrible, as it only meets basic standards used in voice phone calls. (Low audio quality and very choppy with words missed.)I'd also agree with Canada reviews that support quality is low. There has been too much blame on us customer side regardless of fulfilling all operating criteria. Promised improvements also just don't happen, and no firmware updates have come out for over a year.Given this device also runs Andriod 4.4 I suspect it's as good as a discontinued product, so today I'd look for alternatives and only buy it as a last resort.
