About iTRS

How iTRS Works
Video Relay Service and IP Relay users who are deaf or hard of hearing are assigned 10 digit telephone numbers by their chosen “default” provider. These telephone numbers, which automatically create relay calls when they are called by hearing users, are real, local geographic telephone numbers. Relay calls which are direct dialed by hearing callers to deaf or hard of hearing persons use the default relay provider to provide interpreting services. Similarly, a call by a deaf or hard of hearing user to a hearing person may be direct dialed on the deaf/HoH user's IP device and will be placed automatically as a relay call using the default provider.

Meet the FCC Requirement
The FCC requires that all users be able to select an IP TRS provider of their choice for any call. When a hearing person calls a deaf/HoH person using an alternate provider, that provider needs to be able to complete an IP connection to the called deaf/HoH user. The alternate provider uses the Neustar iTRS ENUM database to obtain the IP address of a video device or the Instant Messaging screen name for the called deaf/HoH user. The database is also used when one deaf/HoH user calls another deaf/HoH user and the two parties do not use the same default provider.

Access the Database
The iTRS ENUM Database is available only to VRS and IP Relay providers eligible for reimbursement from the Interstate TRS Fund, and who appear on the NECA reports from the Fund. Entities who are contracted by eligible providers and who actually provide services to eligible providers may also have access to the database.
