Voice Over Internet Protocol (VoIP) and Session Initiation Protocol (SIP) have exploded into the Enterprise Communication and SMB communications space in the last ten years. Some experts believe that the last TDM-only PBX has already shipped, and that in just a few years nearly every business in the world will be using an IP-PBX.
Internally most businesses will be using an IP-PBX. But this does not mean that the PSTN is going away any time soon. There will always be a need to have some connectivity to the traditional telephone network. This is where Sangoma telephony interface boards and media gateways play an important role. Whether a company is interfacing an IP-PBX to the TDM network, allowing a TDM-PBX access to SIP trunks, connecting other legacy voice equipment via SIP, or managing local survivability issues, reliable, high-quality TDM Interface products will always be part of the necessary infrastructure.
Sangoma’s products provide the foundational technology for many of the world’s leading software based IP-PBXs. These include both open-source based and proprietary IP-PBX solutions. With many of our products carrying a lifetime warranty, our IP-PBX application partners count on Sangoma to provide the telephony interface boards on which they build their solutions.
With the recent expansion of our products to include both appliance based VoIP Gateways as well as software based solutions, Sangoma now provides a full portfolio of products that reliably and cost-effectively support IP-PBX solutions from just a few analog ports to those that require dozens of digital spans distributed across multiple offices.
