Brown. “Geographically, sales contributions from our North American and EMEA regions were particularly strong, adding new customers, as well as a significant number of follow-on contracts from current customers. Our enterprise IP telephony offering, which is marketed by Vonexus, continued to grow by a strong double-digit percentage during the quarter compared to the previous quarter.”
