Reliable PSTN Connectivity for Any Phone System

SIP trunking uses internet-based connectivity to connect a business phone system to the public telephone network, allowing organizations to place and receive calls without traditional telephone circuits. 

A Session Border Controller or SBC is dedicated hardware and/or software that controls how phone are secured as well as how calls are initiated, conducted and terminated on a voice over internet protocol (VOIP) network. SBCs act as a router between a network and a carrier service ensuring that all calls are secure and have the highest quality of service possible.

Depending on the customers requirements and design we have either metered trunks or unlimited trunks. Metered trunks are assigned a per minute usage fee for Domestic LD, Local and international calling.  Unlimited trunks have a fixed for unlimited calling based on the package of LD only, Local/LD and international. For unlimited, there is a fair use policy based on normal calling patterns.

The solution comes with a web-based Self Service Orchestration tool that allows you to manage and administer your account. Items such as adding phone numbers, changing route labels, signaling IPs and rerouting traffic are some of the many features available to you for managing your solution.

Yes. Many organizations deploy SIP trunking as a modern replacement for PRI services to reduce costs, improve scalability, and support cloud communications.

SIP trunking can be secured using technologies such as Session Border Controllers (SBCs), encrypted communications, and carrier security controls. COEO offers SBCs and our platform supports secure voice connectivity and interoperability.  

Porting timelines vary by carrier and number quantity. Smaller projects may complete in as little as a few days, while larger projects can require additional coordination.  

COEO SIP Trunking is designed to support virtually any PBX, cloud communications platform, unified communications solution, or hybrid environment.  

PRI (Primary Rate Interface) uses physical copper wires and traditional circuit-switched technology to connect your phone system, while SIP Trunking uses Internet Protocols to provide virtual, packet-switched communication channels. Additionally, PRI can only support voice data, while SIP Trunking handles voice, video, and messaging.

For organizations seeking greater flexibility, lower telecom costs, and improved business continuity, SIP trunking is often the preferred modernization path.
