Also referred to as an IP PBX or a virtual PBX, a hosted PBX refers to a communication service where the call platform (as well as the PBX features and capabilities) are operated and maintained by a third-party service provider off-site. Businesses no longer have to purchase, maintain, or upgrade hardware because the service provider shoulders this responsibility. This allows organizations to focus more on their core competencies, and save moneySponsored Listing
