Our Commitment

We work in an energetic global industry where the pace is fast and change is constant. But, there are some things that don’t change at Ribbon Communications (also, “Ribbon”) - our commitment to doing business honestly, ethically, and with respect for others. It is to this end that Ribbon Communications has implemented this Supplier Code of Conduct (“Code”) which mirrors many of the principles set forth in Ribbon Communication’s Code of Conduct.

It has always been paramount to our way of doing business at Ribbon Communications to comply with applicable law and to act with the utmost integrity, honesty, and transparency. Ribbon Communications is committed to acting responsibly in all our business dealings to ensure that we comply with applicable national and international legislation, including laws regarding anti-corruption, anti-trust, anti-bribery and fair competition, and human rights. Ribbon Communications will forgo business opportunities rather than act in an unethical manner and/or in violation of applicable law. Preserving an ethical workplace is critical to our long-term success as a company.

At Ribbon Communications, the message for each Ribbon Communications’ Supplier is clear: any success that is not achieved lawfully and ethically is no success at all. At Ribbon Communications, we obey applicable law and strive to hold ourselves to the highest ethical standards, and we expect the same of all our Suppliers.
