    Grandstream GS-GXP2170 VoIP Phone & Device

    • Great job Grandstream.
    • (my testing has yielded about a 200ms gap in the speed of processing the voice packets from different phones and manufacturers).This Grandstream feels like a quality product, the screen is bright and brilliant, the pages of BLF keys is a perfect fit.
    • Yealink has some decent phones, but their flagships like the T48g have major latency on their audio.
