As part of a process to modernize Wyoming Relay and ensure its effectiveness, Wyoming will discontinue analog captioned telephone service (CapTel) on January 31, 2026. The Wyoming Relay staff are happy to assist with information on available options for equipment and services to make Internet Protocol Captioned Telephone Service calls or how to use your current analog CapTel phone to make Voice Carry Over (VCO) calls (see below).  

Captioned Telephone Service is used by persons with a hearing disability but some residual hearing. It uses a special telephone or Internet Protocol device via the Internet to simultaneously listen to the other party and read captions of what the other party is saying. Analog CapTel Service is a captioned telephone service that uses analog telephone lines and the public switched telephone network.   

If you have a CapTel model 100, 200, 800, 840, or 840 Plus in analog mode, any calls attempted on these phones after January 31st will work as a standard amplified telephone with no captions. CapTel 840 Plus phones can be changed to digital mode and continue to receive captions. To change the 840 Plus to digital mode, please contact CapTel Customer Service using the blue button on the phone or by dialing 888-269-7477.  

Wyoming Relay Equipment Distribution Program offers Internet Protocol Captioned Telephones and wireless (cellular) telephones with captioning apps. Some equipment models may be similar to what you are currently using, and technical assistance and support are available. To learn more or to apply, click here, call 800-452-1409, or email dws-wyrelay@wyo.gov.  

Internet Protocol Captioned Telephone Service is available nationwide. The Federal Communications Commission maintains a list of providers on their website. Several of these providers also offer Internet Protocol Captioned Telephones.
