⚠️ Deployment Considerations for India (Bengaluru)

Since you’ll likely use this in an Indian/enterprise context, here are important things to verify:

• Network Band Compatibility: Make sure the GSM bands supported match the Indian mobile networks you will use (e.g., 900/1800 MHz are common). If you plan for 4G/VoLTE support, check LTE bands as well (the 8G may be GSM only or limited LTE)

• Channels / Capacity vs Growth: 8 channels may be enough for smaller mobile trunk usage. If you plan to grow to many more mobile lines, check whether you’ll need a 16 or 32 channel model.

• SIM & Antenna Infrastructure: With 8 channels you’ll need 8 SIM cards, 8 antennas or good combiner/antenna setup, proper RF signal strength & isolation to avoid interference in a dense environment.

• SIP/VoIP Integration: Ensure your IP-PBX or SIP trunk supports the codec and signalling you’ll use (e.g., G.729, DTMF modes). Ensure the gateway works well in your network environment (QoS, NAT/firewall).

• Power & Rack Setup: Confirm physical installation space, ventilation, UPS/power availability.

• Support & Firmware: Check that there’s local support in India, that firmware updates are available, and that the parts/spares can be serviced.

• Regulation & Compliance: If using many mobile channels for trunking/origination in India, check regulatory environment, operator permissions, SIM-usage guidelines etc.

• Cost/ROI: Evaluate cost of gateway + SIM cards + antennas + installation + maintenance vs the benefit of using mobile channels (cost saving or redundancy) compared to fixed trunk alternatives.
