Types of Calls

TTY Calls

The Red River Regional Dispatch Center’s telephones are equipped to handle both ASCII and Baudot incoming TTY calls from deaf or hearing/speech impaired callers.

If you use a TTY, you should:
Stay calm, place the phone on the TTY and dial 9-1-1.
After the call is answered, press the TTY keys several times.
Give the call- taker time to connect their TTY.
Tell what is needed: police, fire or ambulance.
Stay on the line if it is safe and answer the call taker’s questions.

Cell Phones

Wireless 9-1-1 is divided into two phases:

Phase I- Your call will come into the 9-1-1 center with the wireless phone call back number, the carrier’s contact number and the location of the tower that received the call.

Phase II – In addition to the above information, this phase gives the 9-1-1 center a more precise geographical location, by using a Global Positioning System (GPS) built into the phone itself. Your phone needs to be Phase II compliant in order for your exact location to be provided. To determine this, consult your cell phone user’s manual. If the cell phone is equipped with a GPS chip, then it is Phase II compliant.

TIPS when calling from a cell phone:
Even though your phone may be Phase II compatible, make sure you know your exact location.
When you dial 9-1-1 from your cell phone it is instantly routed to the nearest cell phone tower and then rerouted to the nearest 9-1-1 center. Keep in mind that this initially may not be the 9-1-1 center from which you need help. After giving your location, you may be rerouted to the correct center.
You may call 9-1-1 from a cell phone that has been disconnected. However, the 9-1-1 center will not receive the cell phone number and will not be able to call you back if you are disconnected. Be sure you give your location.
If you lose contact with 9-1-1 while on a cell phone, call back.

Voice over Internet Protocol

Voice over Internet Protocol (VoIP) phone service is a rapidly growing alternative to traditional phone service due to its low prices and the consumer’s ability to choose a phone number from nearly anywhere in the country.

While VoIP is an attractive option, it is important for consumers to understand the potential limitations the technology has with respect to accessing 9-1-1.

If you are considering buying VoIP service, please visit the website, www.911voip.org which was created to help educate consumers on VoIP telephone services as it relates to accessing 9-1-1 emergency services.
