Due to its open architecture, the platform is compatible with a wide range of VoIP and ATA terminal devices, and supports almost all VoIP communication protocols such as SIP, IAX, MGCP, Skinny and H323, allowing complete freedom with regards to devices and interconnection protocols with the telephone center. The platform, used as a Hybrid PBX, may accept interconnections via the VoIP protocol, as well as TDM protocols. It has been tested and is compatible with telephone centers such as Avaya, Siemens, Alcatel, Teles, Panasonic and others and can be connected at a VoIP SIP level with all IP PBXs that support the SIPv2 protocol. Therefore the platform may be used for the interconnection of remote locations or users, or even for the interconnection of VoIP networks with conventional TDM telephony networks.
