These ports are analog extension ports. On older IP Office units these ports were labeled as POT ports rather than PHONE ports.
PHONE ports on Phone V1/V2 expansion modules can be connected to out-of-building extensions. If this is the case, connection must be made via suitable protective devices (IP Office Barrier Box) at each end and via each building primary protection. In addition the Phone module must be connected to a protective ground.
PHONE ports on IP Office control units must not be connected to out-of-building extensions.

•REN: 2
•Off-Hook Current: 25mA.
•Ring Voltage:
•IP500 V2A Control Unit, IP500 Phone Modules: 49V rms.
•Minimum Wire Size: AWG 26.
•Maximum Cable Length:
•AWG26: 0.5km / 1640 feet.
•AWG24, AWG22: 1km / 3280 feet.
These ports do not include a ringing capacitor. Therefore, for connection to 4-wire analog phones where this is a requirement (typically the United Kingdom and New Zealand), connection should be via a Master socket containing ringing capacitors.
Structured Cabling Line Cord
This is an RJ45 to RJ11 cable suitable for connection from a structured cabling system RJ45 port to a DS phone. It can also be used for two-wire analog phone extensions.
