The truth is decisions are driven by how applications and capabilities match business needs while meeting IT requirements for reliability, security, interoperability, and manageability.   The IP telephony market has coalesced around a common architecture consisting of open servers, highly distributed gateways that connect IP and traditional elements, and a broad range of new access devices, including IP phones, wireless phones, softphones, PDAs, and more.    Interoperability is also important as you consider the benefits of deploying IP telephony globally, so your distributed enterprise can communicate and operate as one highly-effective, integrated entity.
