We have a C90 running firmware version TC7.3.2.14ad7cc.
On our older 6000MXP Units there is an option in permissions to set "Allow Incoming Audio Only Calls" to "Off". I would like to do so with our C90 has started to get random robo h.323 calls.
We don't have it behind a gatekeeper and operate on direct h.323 dial in.
Does the C90 have this function? I haven't been able to find it in the admin guide for the c90. Any help would be most appreciated.
