Some of the major telecommunication relay service (TRS) market participants are Avaya, Bell Canada, Captel, Cisco Systems, Convo Communications, KCOM Group, Purple Communications, Relay UK BT, Skype Technologies, Sorenson Communications, T-Meeting, T-Mobile USA, ZVRS and DeafTawk.

Due to concerns about the lack of a safe and functionally equivalent emergency and public broadcast system in Deaf schools, Convo saw an immediate need for a safer and effective visual emergency and public broadcasting system. Convo Announce is the world's first platform to integrate visual emergency and public notification system with video relay service for schools, businesses, and organizations.

Sprint Relay is proud to present: Sprint Mobile Video Relay Service (Sprint Mobile VRS)

The IWRelay VRS iPhone application allows Deaf users to make mobile phone calls to hearing friends and family members for the first time ever.
