We use S705 devices connected to our FreePBX using VPN.
Our only problem is for internal conference (for the moment we never use it with external calls).
Only the first 2 participant can stay on the conference, the third is disconnected after 30 sec.
Same problem with Zulu connected directly without VPN.
I’ve tried to endable debug, but I can’t understand where the problem comes from.
Any other calls works fine.
Thanks alot for your help !
