SERVICE SPECIFIC TERMS
SENTRY^®

Dated: April 20, 2025

Version 1.1

These Service Specific Terms for SENTRY^® (“SENTRY Terms”) govern Customer’s use of the Services described below and are in addition to and incorporate by reference the First Orion Terms of Service located at https://firstorion.com/first-orion-customer-portal-terms-of-service/ (the “Terms”). Capitalized terms used but not defined in these SENTRY Terms will have the respective meanings assigned to them in the Terms. If you do not agree to these SENTRY Terms or any changes thereto, your sole remedy is to stop using the Services. Use of the Services after any changes shall constitute acceptance of the updated SENTRY Terms.

First Orion’s SENTRY solution (the “Sentry Service” or “Services”) protects against illegal or unwanted spoofing by allowing for the Authentication of calls, such that any call that has not been Authenticated will be blocked.

1. Definitions. The following capitalized terms shall have the meaning set forth below or as set forth in the Terms.

“A number”  means an outbound calling number for Customer which has been vetted and which is used by the Customer for the Sentry Service.

“B number” means the called party number of a subscriber of a Distribution Partner.

“Call Authentication” means an end-to-end authentication method that pairs the A number with the B number at the time of an encrypted call that verifies or authenticates that the call is valid using an application program interface (API), call routing configuration (SIP), or other industry standard protocols.

“Distribution” means the functionality or capability, whether provided by First Orion or a First Orion Distribution Partner, that allows for use of the Sentry Service.

“Program” means the set of instructions provided by Client for management of the A numbers intended for enablement of the Sentry Service.

“Verified (or Authenticated) Call” means a call from an A number delivered to a B number that has been verified using Call Authentication.

2. Distribution. Unless otherwise set forth in the Order, all available Distribution will be enabled for Customer’s use of the Sentry Service.
3. Registration and Certification. As a condition to the Services to be provided hereunder, all Customers must have (i) completed the Registration process for the Customer and each A number(s) being used to make calls using the Sentry Service and (ii) passed the Registration and Certification processes. See the Service Specific Terms for Business Registration and Business Certification. Customer acknowledges the need for accuracy of Customer’s ownership or right to use the A number(s) with regard to the Services and represents and warrants that Customer is the owner or otherwise has the right to use the A number(s) submitted by Customer for registration and use with the Services. Customer must remove any A number from registration and any Programs when Customer no longer owns or has the right to use the A number.
4. Services Description
1. Call Authentication. The Sentry Service allows Customer to block calls that have not been Authenticated before the call terminates in the Distribution Partner network. Prior to initiating a call, a Call Authentication request will be used to submit all required data, including the A number and B number pair which will create a unique hashed key. If any call made from an A number in a Sentry Program is not a Verified Call, the Distribution Partner (or its analytics provider) will be advised to block the call.
2. Accuracy. Customer acknowledges and agrees that (i) Customer is solely responsible for the accuracy of the information submitted in the Authentication request, and First Orion has no liability related to the delivery of, or failure to deliver, calls made by or on behalf of Customer based on inaccurate information submitted in the Authentication request, and (ii) for A numbers Customer has designated for use with the Sentry Service, in the event a call is made from such numbers without an Authentication request (including calls for which no Authentication request is utilized), the Distribution Partner (or its analytics provider) will be advised to block such calls.
3. Agents. Customer may engage a third party to provide the Call Authentication actions to be taken upon origination of a call from Customer’s A number(s). Customer will advise First Orion of the use of any such agents and Customer will be responsible for the agents integrating with First Orion’s Sentry Service so that Customer’s calls can be Authenticated as provided herein. Customer will be solely responsible for the acts or failure to act of its agents.
4. Fees. For use of the Sentry Service, Customer will pay First Orion a fee per Verified Call as set forth in the applicable Order. In addition, First Orion will charge Customer a fee of $1.00 per month for each A number manually vetted as described in Section 6(b) of these SENTRY Terms.

5. First Orion Responsibilities
1. Training and Instructions. First Orion will make available reasonable education and training in order to facilitate Customer’s use of the Services which may be provided through online tutorials and/or instructions. Information related to the use of the Services is available on the Customer Portal.
2. Support Services. Customer support will be available Monday – Friday from 8:00 a.m. – 5:00 p.m. Central Standard Time via Zendesk on the Customer Portal or at enterprisesupport@firstorion.com.
3. Reporting. Standard reporting will be made available in the Customer Portal at no additional charge.

6. Vetting. Provision of the Sentry Service to Customer is subject to initial and ongoing enterprise and A number vetting by First Orion.
1. First Orion provides automated vetting through its Automated Call Center (ACC) option where the automated call center will initiate a phone call to the A numbers provided by Customer. The designated A numbers must be able to receive a phone call, confirm the telephone number registration, and vocalize the name of the registered business. First Orion will record all activity during each interaction for verification purposes. First Orion may modify its automated vetting options from time to time in its sole discretion.
2. In the event Customer’s A numbers cannot be vetted in an automated manner, First Orion may, at Customer’s request, vet the A numbers manually.

7. Service Interruptions. First Orion may suspend the Sentry Service as to any Customer or any A number if (i) Customer or the A number fails to satisfy First Orion’s ongoing verification requirements or (ii) First Orion reasonably believes that A numbers are being blocked in a manner not intended by Customer or outside of the scope of the Sentry Service. First Orion will provide Customer with notice of such suspension, including the reasons for suspension and any required corrective actions as soon as reasonably practicable under the circumstances.

8. Additional Use Restrictions. First Orion may impose additional restrictions and/or prohibitions on the use of the Sentry Service to the extent they are imposed by a Distribution Partner or applicable law. First Orion will notify Customer of any such restrictions and/or prohibitions as soon as reasonably possible after receiving notice thereof. Customer agrees to comply with such restrictions.

9. Onboarding of Customer. Customer acknowledges that First Orion will use the following process for enabling the Sentry Service on the Distribution Partner networks.
1. Enablement on T-Mobile Network – First Orion will first enable the Services on the T-Mobile network for no less than 14 calendar days. As result of such enablement, First Orion will provide the remaining Distribution Partners (or their service providers) with a report containing key metrics (e.g., total number of call termination attempts, total number of blocked calls) and any key issues or observations for review by such Distribution Partners (or their service providers).
2. Enablement on remaining Distribution Partners Networks – Upon approval from a Distribution Partner (or its service provider) other than T-Mobile based on the report submitted under subsection (i) above, First Orion will work with such Distribution Partner (or its service provider) to enable the Services on such Distribution Partner’s network in monitoring only mode (no blocking) for no less than 14 calendar days at which time the Distribution Partner (or its service provider) will prepare a report containing key metrics (e.g., total number of call termination attempts, total number of calls that would have been blocked) and any key issues or observations to Distribution Partner (or its service provider) for review.
3. Blocking on remaining Distribution Partner Network – Upon approval from a Distribution Partner (or its service provider) other than T-Mobile based on the report provided in subsection (ii) above, First Orion will work with the Distribution Partner (or its service provider) to enable the Service for Customer on such Distribution Partner’s network in blocking mode. First Orion will work in good faith to obtain such other Distribution Partner’s (or its service provider’s) approval to enable blocking within 30 days of when monitoring on such other Distribution Partner’s network begins. In some instances, billing will commence upon a Distribution Partner enabling the Service in monitoring mode (i.e., Call Authentication is taking place, but for calls not Authenticated, the Distribution Partner will not be advised to block). The Parties can extend the 30-day monitoring period if it is mutually agreed upon.
