We have a newly installed FreePBX server hosted by Cyberlynk.
The PBX was setup by our SIP trunk provider.
Currently the UniFi phones receive calls but with no audio. The UniFi phones send audio to the other caller fine.
We need someone who has experience with Hosted FreePBX AND UniFi VoIP phones to assist with resolving this audio issue.
There's not much documentation on the UniFi phones and they are difficult to work with so please only apply if you have this exact experience and can resolve our issue.
