SIP Trunking for Resellers

What is SIP Trunk Reselling?

SIP trunk reselling is a business model where a company resells SIP trunking services to other businesses or individuals. The reseller purchases SIP trunks in bulk from a SIP trunk provider and then resells them to their own clients at a markup. The reseller is responsible for managing their clients’ accounts and providing technical support, while the SIP trunk provider handles the infrastructure and network connectivity. This allows resellers to offer SIP trunking services to their clients without having to invest in expensive network infrastructure or expertise.
