Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line.

Mobility is one of the primary benefits of using voice over IP (VoIP) devices. However, this benefit can complicate the effectiveness of 911 emergency services. Clemson University’s support of 911 emergency dialing from IP phones, soft phones, and extension mobility devices is safe and reliable when you are in the original location given to Telecommunications for that device and phone number.
The physical location where you will be using our service is required for 911 purposes.


To active VOIP, consent/affirmation is required: 

- VoIP service may not work during a power outage, or when the Internet connection fails or becomes overloaded.
- VoIP 911 calls may correctly connect to the PSAP, but not automatically transmit the user’s phone number and/or location information.
- VoIP customers may need to provide location or other information to their VOIP providers for their VoIP 911 service to function properly.
- VoIP customers should NOT dial 911 from a mobile Soft Phone (i.e. Jabber or WebEx Teams) device.
