Review on Grandstream GS-GXP2170 VoIP Phone and Device by Kevin Singh

Used in a free PBX/PBXACT SIP system for several weeks. This phone is better than the Sangoma S705 phones we originally bought. The call quality is better, the speaker is better, and the screen is slightly better. The phone is also more durable than the Sangoma. However, the display is still very difficult to see unless you're looking straight ahead. The phone has a cheap plastic look. Both Yealink and Polycom make higher quality phones in my opinion, but I would prefer them to Sangoma phones simply for the consistent speaker/earpiece quality. This is definitely a cheaper option and should not be abandoned completely.
