Hi all,
UCaaS solution for a customer with Revolabs SIP conference units. I can register them no worries but get one way speech.
External caller can hear, but the units cannot. This happens for internal caller as well!
Revolabs --> MBG --> MiVB
All ports are open. I've had a similar issue before for a Konftel unit where the STUN server needed adding...but I've tried this to no avail.
Any ideas would be great
Thank you
