Notes about the SLN file extension:

To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened" (Windows 7) or "How do you want to open this file?" (Windows 10) if you double-click the file. There click on "More apps" and choose a suitable software to view such files on your PC or from email attachments.

The SLN file type is primarily associated with 'Asterisk' by Digium, Inc..

Asterisk is the world's leading open source PBX, telephony engine, and telephony applications toolkit. Offering flexibility, Asterisk empowers developers and integrators to create advanced communication solutions...for free.

PBX: Private Branch eXchange. A PBX is simply a private telephone network, which is used within a company. While the number (called an "extension") each user uses is unique, all of the users share a single number to the outside world; one that is assigned by the telephone company. A PBX is also usually more cost efficient than connecting each individual telephone to an outside line. In addition, a user must only dial an extension, which is usually several digits shorter than a normal telephone number, to reach the desired party.
