Hoping someone can point me in the right direction. Very strange use case, HT812 on a self-contained no internet network. I have FreePBX running perfectly. HT812 registers and works perfectly when I have the WAN connected to internet. Disconnect internet? Immediately starts acting weird.
HT812 to Softphone:
Call immediately gets placed on hold???
Softphone to HT812:
HT812 to Virtual Voicemail Extension:
No audio, despite Asterisk playing it.
Softphone to virtual voicemail extension works perfect as well, even without internet.
I’ve been in VoIP for many, many years, and I’ve never seen anything like this.
