Dialog Permissions

From Pbxnsip Wiki

User agents may subscribe for the dialog state of any extension in the domain. The dialog state is typically used to control a LED on a hard phone, or list the ongoing call on a soft phone display. By default, there is no restriction on who may subscribe to which account. However, there are cases when you want to limit the permissions to do that.

Every account has a field called dialog permissions. This field lists the extensions that may subscribe to the state of the account. If the field is empty, everyone may subscribe. Otherwise it lists the accounts that may subscribe to the state of that account. You may use Wildcard Patterns to match more than one account (e.g. 4* to allow all extensions that start with a 4).
