     SIM cards rotation.

2) It can connect with ordinary telephone set, PBX , VOIP Gateway, Billing meter etc.;

3) Dialing tone frequency:450hz;

4) Employ Industrial module Sim300(900/1800/1900Mhz),Sim340 (850/900/1800/1900Mhz) or Wavecom Q2303A,Q2403A,SIM300W ( 900/1800Mhz)], Quectel M10 to make;

5) Can adjust dial interval from 0.5sec to 9 secs by setting up from telephone set;

6) Can adjust voice volume by setting up from telephone set;

7) SIM card supported (1.8V, 3V);
8) Caller ID display and hide;
9) DTMF Dialing;
10) Bell signal;
11) Polarity reversal;
12) The RJ-11 socket which connect the phone or billing system for metering purpose;
13) Antenna socket (SMA);
14) IP Presetting;
15) Working status and Signal Strength by LED indicator;                                               

16) IMEI Change (optional)

Key functions: 

1) IMEI change by DTMF from telephone set;
2) SIM rotation;
3) Auto IMEI change when SIM rotation.
    - rotator by really clock (4 time o’clock)
    - rotator by dial times
    - rotator by total talking minutes
    - rotator by working hours
 4) GSM 8 ports FWT with IMEI changer
      PS: You can change the IMEI to any 15-digital code or One Number Unified. These are the typical points of 64 sims 8 ports GSM FWT-8888(GATEWAY).
