When using Sigma Voice’s services, it’s important to ensure that your communications are compliant with industry regulations and consumer protection laws. Below are key legal considerations for voice and SMS broadcasting, IVR solutions, and telecom auditing:

Clearly identify your organization and the purpose of your call or message at the beginning of each communication to avoid misleading recipients.
Protect recipient information by using secure contact storage methods and comply with data protection laws like GDPR or CCPA where applicable.
