More power - MORE flexibility - GREATER system expansion .. update module for the existing IT-770 and IT 730 IT systems. By the use/exchange of the module with the same performance options such as one-730 plus, or 770 IT plus It means that IT is 730 IT, and 60 user with 90 devices can manage and 770 IT plus 200 users with 120 devices (each, regardless of the device type) In addition to the 2 network interfaces (optional network separation with the use of the ETH-Plus-license), you can manage the module from the home up to 64 IP channels (without dying need for additional hardware extension), thus forming die max. Limit of existing/potential IP module in existing systems. Use variants of channels: SIP external SIP Provider, SIP internally (SIP devices, AGFEO DECT IP), ASIP (AGFEO ST for the IP interface). After the use of IT 7xx-Upgrade Kits for existing IP can not be used module in this System (IP channel license transfer in exchange for the IP module. Replacement modules can be used in other systems.)
