 AS551 Master/Slave

The AS551 is our solution for big companies, who wish to save on mobile telephone cost. The product can be connected on a PRI-trunk or in Passthrough modus. It is flexibel and can easily be extended from 6 to 30 GSM-channels.
Apart from all the known features of our AS54xx-series, it is also possible to use optionally the GSM Mobility Extender feature. This feature makes it possible to use the mobile phone as an internal extension of the PABX. This makes this solution the ultimate DECT-alternative.
Mobile Twinning is also possible. Both fixed and mobile phone will then simultaneously ring.
