is it possible to connect GDS3710 to GXP1610?
Appreciated for an urgent response
GXP1610 is not color graphic LCD therefore no image or video will be displayed on the LCD, also the LCD is too small.
But if you referring to one button open door feature, or DTMF open door, then the answer is YES.
GXP1610 will work with GDS3710 to ope door, when SIP call established.
Hope this helps. Thank you for your interest to Grandstream products.
