I have a client that is having issues paging between phones. We have ran this as far up the flagpole as possible and grandstream engineers have been HORRIBLE to work with. So much so that I am considering switching equipment providers.
The issue we have is when we dial the extension number from handset to handset it connects but there is no audio. If we use the intercom feature we get a "Voicemail not setup for this extension" recording. The intercom calls are not hitting our PBX which is correct, but I have no idea where the greeting is coming from. We are using a cloud instance in AWS and the cordless are connected via STUN using the Grandstream 3cx template.
Does anyone have any advice on either resolving the no audio issue or how to make the handset to handset intercom function or another DECT or wifi solution that works properly?
