GDS3710 and GHP62x

[mlarosa63]

Are GHP6xx phones compatible for video viewing of calls via GDS3710 or is the call audio only?

GHP62x is audio only phone, therefore no way can see the video. But if enabled DTMF open door, it can enter remote open door PIN from GHP62x and open door remotely if configured.
