Connecting a paging system to a Communication Manager gateway as a station is significantly less complex than connecting it as a CO trunk. Compare this post to my immediately previous post about paging via trunks.

Determine the extension number that you’re going to assign to the station. Determine what unassigned analog station port you will be assigning. Administer the station as type 2500 (which is a generic analog phone). Administer the station name leading with two tilde marks so that it does not appear in the on-board station directory. Some paging systems will misbehave if the PBX attempts to test the station – set Tests? to n if that is the case. Ensure that you do not administer a security code or coverage path.

Once you’ve administered the station in CM, physically connect the paging system to the port you assigned. I strongly recommend using a butt-set to ensure that you’re connecting the correct ports together. Making a mistake may cause equipment damage to the paging system, your phone system, or both.

Users may access the paging system by dialing the extension you assigned to that station.
