Our intercoms don't support black/whitelisting by default. However, you can do it in a PBX or using automation. If you'd like to use automation, you'll need Gold or Enhanced Integration license first.
The Number parameter at the event CallStateChanged can contain a phone number or an IP address.
The following is an example of a whitelist. If you'd like to make a blacklist, just swap action AnswerCall for the EndCall one.
Please note that it's better to set up a whitelist, since blacklists can be easily bypassed by changing your number to a different one. For whitelisted values, you need to know the exact number that can get through.
You can download the automation here: Whitelist.am
Here you can see how to configure it for more than one number. Whitelist.am
Note: All commands used in the Automation section are deeply described in our 2N® IP Intercom Automation manual where are also some examples. This manual is available on our web pages:
