CallCenterUSA SMS Alerts is a messaging service that notifies healthcare professionals when urgent or emergency secure messages are waiting in the SecureLinx app. Messages are sent by CallCenterUSA, operated by Silver Rock Enterprises Inc.
By providing your mobile phone number through the CallCenterUSA SecureLinx platform, or by having an authorized administrator enable SMS alerts on your account, you consent to receive automated text messages from Silver Rock Enterprises Inc. operating under the CallCenterUSA brand.
Consent is not a condition of service — your organization can disable SMS alerts at any time.
You will receive SMS text messages alerting you to urgent and emergency secure messages. Messages contain no patient information or protected health information (PHI).
Example messages:
"CallCenterUSA Alert: You have an urgent secure message waiting. Open the SecureLinx app to view. Reply STOP to opt out."
"CallCenterUSA Emergency: You have an emergency secure message requiring immediate attention. Open the app now. Reply STOP to opt out."
Message frequency varies depending on service and operational conditions. You will receive an SMS only when an urgent or emergency secure message is delivered to your SecureLinx account. Typical frequency: 0-10 messages per day.
Reply STOP to any CallCenterUSA message to opt out of SMS alerts. You will receive a one-time confirmation message. No further messages will be sent unless you re-subscribe.
You may re-subscribe at any time by replying START or by contacting your system administrator.
