GXP1625 Calling but cant hear or speak anything



We got a new pair of GXP1625, configured them and the work but for some reason, you can’t hear anything and the other person can hear anything when you are on a call.

Any approach to this.



Make sure you have cord plugged into handset and not headset. Would need more info about your setup to help any further.


problem with NAT or handset inserted in the wrong plug, put both handsfree and make a conversation see if the audio is dual-channel.
