An extension is an internal telephone line. Each user can have assigned one or more extensions in Kerio Operator.
The total number of extensions is limited to three times the number of licensed users.
Service extensions configured on the PBX services tab are not counted by the license file.
Adding new extensions
You have three options to add a new extension:
Creating a standalone extension
If you have a phone which is not used by any particular user, you can create a standalone extension for it.
SIP username and SIP password
Each extension has a SIP username and a SIP password. Kerio Operator uses SIP usernames and SIP passwords for authentication of phones to Kerio Operator. You use SIP username/password for connecting softphones or hardware phones to Kerio Operator (read more in the Configuring multiple registration of an extension article).
SIP usernames/passwords cannot be used to login into Kerio Operator or Kerio Operator Softphone.
Using SIP username/password
Now you can view the SIP username/password and use it for connecting a phone to Kerio Operator.
In Kerio Operator, you can encrypt your calls for any extensions.
Now Kerio Operator encrypts all calls for the selected extension.
