Hi Guys,

Hoping somebody out there can help me... I am a bit of a novice when it comes to 3cx. but I have an active 3cx system in place with extensions. All extension use a mobile softphone apart from my desk. Which I have just bought a GXP1610 to replace my cisco handset. Used auto provision, and it is connected and can make and receive calls... BUT for some reason people can hear me, but I cant hear them. this is happening on internal and external calls... so not sure whats going on.

Hi Ewan,

When you provisioned the phone in your management console what method did you choose?



And most importantly, where is this PBX hosted? Same LAN as the phone or in the cloud?

I used direct sip and the phone is on the same lan as the pbx.

Ok then in this case the phone appears to be misconfigured.

I suggest you follow the below guide to factory reset it, and reconfigure it using the method that applies to your case
