Flexible Infrastructure, On Demand

Unify your voice and data communications securely and efficiently.


SIP Trunking

Session Initiated Protocol (SIP) is a signaling procedure widely used for controlling communications, like voice calls and video calls over the internet. SIP trunking can deliver local, toll-free, domestic, and international long-distance service. Telecom Metric’s SIP trunks allow for secure, quick, flexible, and cost-effective scalability, as opposed to the traditional PRI or analog lines which are slow to scale and costly. Only pay for what you need, and when you need more, we are right there to help.
