• Physical / Power: The datasheet for the UC2000-VG shows e.g., power supply 100-240V AC, power consumption ~68W for the “-32W” variant, dimension ~440×270×75 mm, weight ~5.5kg. Scribd

⚠️ Considerations & What to Verify Before Purchase

Because you’re in India / Bengaluru, and deploying a high-channel gateway, it’s important to check these:

• LTE / VoLTE Band Compatibility: India uses particular LTE bands for VoLTE (for example B3, B5, B8 etc). Confirm that the specific unit supports the required Indian bands under LTE/VoLTE mode. Although the specs list “multiple frequency choices for different countries” for the UC2000-VG. dinstar.com+1

• Sim/antenna planning: 32 channels means 32 antennas (or appropriate combiners) + 32 SIMs. You need to ensure good RF coverage and isolation to avoid interference.

• SIP trunk / VoIP integration: Verify that the gateway integrates cleanly with your IP-PBX or SIP trunk. Check dial plans, codecs (especially if you plan G.729), DTMF handling (RFC2833, SIP INFO), and network QoS.

• Power / Rack / Cooling: The power consumption (~68W) and physical size means you’ll need sufficient rack space, ventilation, and UPS/power supply.

• Support / firmware / spare parts: Check local Indian distributor support for Dinstar, firmware updates, spares (e.g., antenna ports, modules) and warranty.

• Regulatory / Compliance: Using mobile gateways for termination/origination in India may have regulatory implications (SIM usage, operator agreements). Ensure you are compliant with telecom regulations.

• Scalability and future proofing: Since this supports GSM/3G/4G, you’re somewhat future-proofed. But confirm for your use case what growth might look like (e.g., more than 32 channels later).

• Cost & Total Deployment: Beyond hardware cost, factor in SIM cards, antennas, installation/commissioning, licencing (if any), and maintenance overhead.
