Preparing for and setting up your STS calls

Can I request a specific STS operator?

While we cannot accept requests for specific STS operators, all of our operators trained to handle calls for people with speech differences.

Can the STS operator make calls or leave messages for me without me calling in?

An STS user must start a call before the STS operator can leave a message.

How far in advance can I set up my STS Call?

If you completed a Customer Profile, you can set up a call up to 24 hours in advance.

Can I give the STS operator several instructions before the call?

Yes, the STS user can instruct the operator how they would like their call to be announced, handled and any information about the call that may help the STS operator complete a successful call.

Can I make a 911 emergency call?

Yes. In the event of an emergency, dial 911 directly. You may use the Speech-to-Speech service by dialing 877-787-2606 (or *787 if your wireless phone is on the T-Mobile network) to call 911 services.  Using STS services may not be as fast as dialing 911 directly. Be prepared to provide your full name, description of emergency and location. Learn more.

General STS information

Is the content of my calls kept confidential?

Yes, all STS operators are required to keep the contents of their calls completely confidential.

Can I use STS for my international calls? Yes! You can make international calls through the Speech-to-Speech service. People outside the US wanting to call you should dial 605-224-1837 to reach a STS operator.
What information should I include in my STS Call Setup?

STS Call Setup is an optional feature to help speed up call processing for a specific STS call. TRS Customer Profile (see above) is required before using the STS Call Setup form.

• Phone number and name of person/business you plan to call

• Announcement for STS operator to make to the person/business at the start of your STS call (e.g., “This is John calling to check on my puppy.”)

• Instructions for STS operator (e.g., details about the subject of the call, call handling preferences, or anything to make the call easier)
