Hi All
Would need your advise on this
I have a set of SX20 that is configured as a standalone device (No CUCM, VCS).
Its work fine, able to make and receive call via IP address.
The things is, during our Video Conference meeting, sometimes an unwanted number would call us and disturb the flow of the meeting.
I'm not sure how they get our IP address, but we do not expect their call.
Is there any way/setting to block the unwanted number from calling us or disturb us during the Video conference meeting.
Is there any configuration on that i need to set on SX20 itself to prevent this unwanted number from calling us
Please advise
Syahrir
