SIP Trunking Solutions for Businesses of All Sizes

Clear SIP Trunking enables your business to reduce costs and simplify IT management by combining voice and Internet access over a single Internet connection using your existing IP PBX system. With SIP Trunking, you purchase only the trunks you need based on the maximum number of concurrent calls your business requires.

SIP Trunks are significantly less expensive than analog lines, further helping businesses reduce costs. Clear Rate offers SIP Trunking for single-site businesses and Enterprise Trunking for multi-location businesses.

Streamline communications across multiple locations with Enterprise Trunking.

Enterprise Trunking is Clear Rate’s SIP Trunking solution for multi-location businesses. Enterprise Trunking optimizes network capacity across all locations by enabling businesses to leverage enterprise-level trunking resources to meet peak traffic requirements at each location. For added savings, employees share call capacity and receive free on-net calling between all locations.

Bring your own broadband or bundle Clear Rate Voice and Data.

SIP Trunking and Enterprise Trunking can be purchased as a stand-alone solution—customers bring their own broadband—or as a fully integrated Voice and Data solution.
