What types of telephones will function with the Phone Power Service?

Telephones that are labeled FCC part 68 compliant and most analog standard telephones will function with the Phone Power service.

Telephones that will not function properly with the service are digital proprietary phones that are made for specific PBX phone systems. These are usually business, multiple line phones that were part of a PBX phone system at one time. Also, some multiple line phones might cause calling issues when the phone is connected to both phone ports of a Cloned Line enabled device.
