⚠️ Deployment Considerations & Things to Verify

Since you’re based in Bengaluru (India) and likely integrating into an enterprise or call-centre setup, here are important checks before buying:

• Band Compatibility: Make sure the model supports the LTE bands used by your mobile network operators in India (if you plan to use LTE/VoLTE). If it’s mostly GSM/3G only, that limits future proofing.

• Sim Management & Antenna Setup: With 32 channels you’ll need 32 SIMs and adequate antennas or antenna combiners. Ensure RF signal strength / isolation is well planned.

• Integration with SIP/IP-PBX: Confirm codec support (G.711, G.729 etc), DTMF modes (RFC2833, SIP INFO), SIP trunk compatibility with your IP-PBX.

• Power/Cooling & Rack Space: 32 ports = more heat, more power. Ensure your installation has adequate ventilation and stable power supply.

• Support & Warranty in India: Check local distributor for firmware updates, spare parts, warranty coverage.

• Regulatory/Operator Compliance: In India using mobile gateways for certain types of termination may need regulatory compliance – check with local laws.

• Cost of Ownership: Beyond the hardware cost, account for SIM cards, installation, antennas, maintenance, power, and network bandwidth.
