Hi!
We have a T53W in a remote location provisioned by STUN. Our 3CX system is hosted in the cloud on a VM.
The phone has been working fine for a while. Suddenly, it stopped receiving incoming and outgoing audio.
The device itself is functional; we have audio in both the speaker and handset when pressing digits, the ringtone play when receiving a call, but there is no audio when making a call or trying the Echo service. The same issue occurs for voicemail or internal calls.
I attempted to factory reset the phone and have it reprovisioned. I also tried changing the ports for the RTP without success. I checked the firewall at the remote location, and all the ports are okay.
Phone calls go through, as it rings the internal extensions and external phone numbers, but once again, no audio is heard. I also experimented with PBX delivery options such as auto, invite, and others in the Extension tab, but without any success.
