Your telephone is a social connection, your link to family, friends, the workplace, and even a lifeline when you need help. If using the telephone has become difficult, it's time to get in touch with us. We have free products and services that can make using the telephone easier.
Service Centers
Our Service Centers are staffed by Customer Assistants (CAs) who assess the needs of consumers first hand and train them in using our specialized telephone equipment. Field Advisors (FAs) travel to consumers' homes and provide assistance with installation and set up of the telephone equipment, as well as training in the use of the equipment.

Equipment Trials
Periodically, we conduct field trials to determine which pieces of equipment would work best for our consumers. To that end, we invite assistance from consumers and ask them to participate in product trials and evaluation. During that period we ask the consumer to maintain a journal about their experiences with the equipment. In addition, we ask that each consumer fill out and return a detailed Equipment Checklist and Trial Survey.
After evaluating the results, the Equipment Department will present a report to the Equipment Program Advisory Committee (EPAC) detailing the findings of the trial, and they will also provide a summary of their opinions regarding the feasibility of offering the new piece of equipment to the program.
If you are interested in participating in field trials, please feel free to contact the Equipment Department and provide us with your contact information and the type of equipment you are interested in evaluating. We will keep your name on file, click here.
The following field trials are currently underway:
CapTel (Captioned Telephone) provides word-for-word captions of everything said by the other party in a telephone conversation. At the same time, the voice can be heard via an amplified handset. Users with intelligible speech who are deaf or hard of hearing speak directly to the other party. Conversations flow at a near-normal pace.
A person calling to a CapTel user first dials an 800 number to connect to the Captioning Center . Using speech-to-text software, a specially trained operator repeats everything the caller says. A computer converts this to text which is sent to the CapTel user's screen at the same time the other party's voiced conversation is heard via the handset.
When a CapTel user places an outgoing call, it is automatically connected to the Captioning Center . For more information on this phone please visit http://www.captionedtelephone.com/
California is currently conducting a trial of the CapTel phone and service to evaluate this product before it is permanently added to the DDTP's equipment distribution program. People interested in the trial may complete an application and be added to the trial's waiting list. Volunteers are added to the waiting list and trial on a first come, first served basis.
If you have questions about the trial or are interested in joining the trial, please contact the CRS Department of the DDTP.
