SIP Telephone Notice

Notice to Customers Using SIP Telephones

 1.  SIP/VoIP products may not work if power to the system is interrupted or if the end user’s telephone services or local area network (“LAN”) is interrupted, depending on the system design and configuration.

 Note: CTC-Connect  recommends customer installations use Uninterruptible Power Supplies (UPS) to support temporary power interruptions. Extended UPS support is available, but additional charges may apply.

 2.  SIP/VoIP products may not provide the location of the phone extension to emergency services (911/E911) depending on the system design and configuration.

Note: CTC-Connect includes Emergency Notification that is validated through the National E911 system database. Once your service is validated, you are in compliance. It is the customer’s (end-user) responsibility to update E911 address information if a telephone is moved to another location.

 3. The end user should consider having at least one of its telephone lines connected to a telephone that is (1) is separate from their system and (2) does not require separate power in order to dial emergency services.

Note: A single POTS line provides a lifeline/redundancy for emergencies, safety, unusual applications and overflow.
