Hi ,
I have a Siemens HICOM 350H PBX system with 500 lines . I want to
buy another PBX system which is IP enabled and tie both of these in order to
have a total of 1000 lines . One of the options is through ISDN line and the
other through Fiber optic cable.
what would be the hardware required on both the ends for the purpose. It would
be nice if details for both configurations are provided.
regards
anik
