We partner with several providers of VOIP systems so that we can provide you a turnkey system ranging from a few handset hosted PBX system to a fully redundant onsite PBX with video conferencing, call recording, advanced reporting, and call presence information. Different vendors work in different cost models (some may charge per handset, some charge per call path, some include hardware in their monthly cost, etc.), so we work with several to get you the most aggressive pricing to meet your business goals.
