These terms for the Ribbon Inbound Voice Services are expressly incorporated into the agreement pertaining to the voice services described herein entered into by Customer and one of the operating entities that is a subsidiary of Ribbon Communications Inc. (“Ribbon Communications”) including any relevant amendments or addendums (the “Agreement”).  All capitalized terms used herein are as defined in the Agreement unless otherwise specified herein.

1.      Service Description.

1.2        Where commercially available, domestic telephone numbers associated with the Ribbon Inbound Voice Services will be provided by Ribbon Communications or ported from the end user’s existing service provider. The timing and portability of telephone numbers from end user’s existing service provider depend on that releasing provider’s policies, and therefore are not guaranteed by Ribbon Communications.

2.      Rates.

2.1        Ribbon Communications will calculate all minute-of-use based Rates on the number of seconds from when an answer supervision signal is recorded to when a disconnect signal occurs, and will bill in sixty (60) second minimums with sixty (60) second increments.

2.2        Ribbon Communications will provide Rates for Ribbon Inbound Service as outlined in the applicable exhibit to the Agreement with the Customer.

3.2        The Ribbon Inbound Voice Services are intended to be used for general purpose enterprise usage (which may include conferencing or enterprise contact center usage). Ribbon Communications strictly prohibits any use of the Ribbon Inbound Voice Services inconsistent with the purpose, including without limitation that traffic patterns fail to conform to a natural distribution determined by Ribbon using its sole discretion across RBOC, ILEC, CLEC and wireless origination points (collectively “Prohibited Uses”).

3.3        Ribbon Communications will monitor usage patterns and notify Customer of any usage that appears to be Prohibited Use(s), and reserves the right to take any unusual activity as determined by Ribbon using its sole discretion into account in making its determination. If Customer does not correct the Prohibited Use by the end of the billing cycle following the notification by Ribbon Communications, or if Prohibited Uses appear in any subsequent billing cycles, Ribbon Communications reserves the right, in its sole discretion and without any additional notice, to adjust the amounts invoiced to Customer for any affected billing cycles to reflect the appropriate pricing for such Prohibited Uses or terminate the Agreement.

4.      Cooperation with Third Parties.

4.1     Ribbon Communications is providing the Voice Services through third party service providers with whom Ribbon Communications has entered into a contractual relationship whereby it can offer the voice services the subject of this Service Specific Description to the Customer.
