North American Numbering Plan

The North American Numbering Plan (NANP) is an integrated system for telephone numbering serving 20 countries in North America. This extensive network includes the United States, Canada, and numerous Caribbean nations such as Bermuda, Anguilla, Antigua & Barbuda, the Bahamas, Barbados, the British Virgin Islands, the Cayman Islands, Dominica, the Dominican Republic, Grenada, Jamaica, Montserrat, Sint Maarten, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, Trinidad and Tobago, and Turks & Caicos. Each of these countries shares the resources of the NANP, facilitating streamlined and consistent telecommunication across the region.


IVR (Interactive Voice Response) is a technology that allows automated interactions with callers through voice commands and key inputs. It's an efficient tool for managing high call volumes, providing consistent customer service, and streamlining various business processes. One of its notable features is the ability to conduct IVR surveys, enabling businesses to collect valuable feedback directly from customers through automated phone surveys. In international contexts, IVR systems can be pivotal for reaching diverse audiences, offering multilingual support, and tailoring services to different cultural contexts, thus enhancing customer engagement across various regions.

SMS Broadcasting

SMS Broadcasting, or mass texting, is a service that enables businesses to send text messages to a large number of recipients simultaneously. This is particularly advantageous for international clients looking to engage in mass outreach across different regions. It allows for timely and direct communication with a global audience, crucial for marketing, alerts, and updates. For international use, compliance with regional communication laws and adherence to best practices is paramount to ensure the messages are received well and respect local regulations and cultural norms.

Voice Broadcasting

Voice Broadcasting, encompassing automated calling, mass calling, text to speech phone calls, and robocalls, offers a powerful tool for reaching a wide audience quickly and efficiently. This service is invaluable for international markets, facilitating timely and direct communication across different regions. It is particularly useful for emergency alerts, marketing, and informational broadcasts. Voice Broadcasting can be customized to suit the diverse needs of an international clientele, including language preferences and culturally relevant messaging, ensuring effective communication and adherence to global best practices.
