[. . . ] [. . . ] Basically, it supports generic SIP firmware running under a universal SIP server. But for a variety of application requirements or ODM customization, it also can support different solutions, including different IP-PBX/ soft-switch / IP-Centrex (SIP-B) / Serverless (Peer-2Peer) architectures. Basically, this series offers PoE model IP2008B and non-PoE IP2008 (wall-mount power adapter) model. And an Extended Dial Module (IP-EDM) is optional to extend its powerful programmable call/phone features or perform more IP-PBX supplementary features.
