The wideband G.722 audio standard has been implemented with this telephone. It enables voice quality to be better than comparable ISDN telephones and sets quality criteria with MOS values >4.5. The IP241 has been optimised for operation on the innovaphone PBX and can use all the features of the telephone system. It is entirely standards-based under SIP and H.323, and can be powered over ethernet. A second network connection enables loop-through to the computer network connection or allows other network components to be operated on the device.
An extension module with 30 extra direct dialling keys is available for the IP241 telephone. An LED on the key shows the partner’s status. Each key can be labelled individually. Up to 3 extension modules can be connected to one telephone. Electricity supply should be dimensioned accordingly in order to operate several extension modules on one telephone.
