⚠️ Important Clarifications & Deployment Considerations

Since you are in Bengaluru and may integrate this into an enterprise setup, here are things you must verify:

1. Exact model variant and network support

   • Confirm whether your purchased unit is the “DXG-3200G” (2G/3G GSM) or “DXG-3200X” (2G/3G/4G LTE) variant. The “X” version explicitly mentions LTE support. staging.epicglobal.co.in+1

   • For India, check the mobile network bands your SIMs/operators use (particularly for 4G/VoLTE if needed). If only 2G/3G is supported, future proofing might be limited.

2. Channel & SIM management

   • 32 ports means up to 32 concurrent mobile channels. Ensure adequate antenna infrastructure (32 antennas or adequate combiners), appropriate power and RF isolation.

   • SIM card management: Many channels mean many SIMs; check how the unit handles SIM rotation, PIN management, SIM-freeze when network fails etc.

3. VoIP integration

   • Ensure SIP trunk/VoIP side: codecs supported, DTMF methods (RFC2833, SIP INFO, in-band), NAT/firewall handling.

   • Confirm how many concurrent calls the unit can handle (32 channels under full load may stress hardware or network unless specs guarantee).

4. RF/antenna/power environment

   • With 32 mobile channels, RF planning is critical: antennas, signal strength, isolation, potential interference.

   • Ensure proper power supply. The spec sheet for the “X” variant lists input 12V ±10% 23A (!) for the 32-port version. staging.epicglobal.co.in

   • Ventilation and rack space are important.

5. Support, firmware, local distributor

   • Ensure you have a reseller/distributor in India who can support firmware updates, spares (SIM tray modules, power supply) and local service.

   • Verify warranty and after-sales terms.

6. Regulatory/compliance issues

   • Using GSM gateways in India may have operator/regulatory implications (network licensing, SIM usage, bulk termination). Make sure you are compliant with local telecom regulations.

   • Check whether the gateway supports relevant mobile network operator restrictions.
