⚠️ What to Verify / Consider Before Deployment

For your context (enterprise / office setup in Bengaluru), here are important checks and questions:

1. Analogue Device Compatibility

   • Ensure the analogue phones / fax / POS devices you have are compatible with the FXS port specs of the gateway (ring voltage, impedance etc).

   • If you have fax machines or POS, test the T.38 or analog pass-through reliably under network load.

2. Network & SIP Integration

   • Make sure your SIP trunk or IP-PBX supports the required codecs and DTMF modes (RFC2833, SIP INFO, in-band) and that the gateway supports those modes.

   • Ensure VLAN and QoS setup on your network to prioritise voice traffic, since 16 analogue ports may generate significant SIP/RTP traffic.

3. Scalability / Growth

   • If you might expand beyond 16 analogue devices in future (for example to 24 or 32 ports), check whether Dinstar offers higher-port models in the same family (they do) and whether you’ll want a single gateway sized up front.

   • Check how the gateway handles concurrent calls when fully loaded — e.g., if all 16 ports are active with voice + fax, what is the max simultaneous performance.

4. Power / Rack & Environmental Setup

   • Ensure your rack space can accommodate the unit (dimensions above) and that you have proper ventilation and power supply.

   • Power consumption is modest (~30W) but consider UPS/back-up if you need high availability.

5. Support & Firmware Updates

   • Confirm local distributor/reseller support in India, firmware update policy, spare parts availability (especially for analog line modules).

   • Check warranty terms.

6. Cost of Ownership

   • Beyond hardware cost, include installation, configuration, licencing (if any), training for staff, maintenance.

   • If using many analogue devices, consider if eventually migrating to IP phones makes sense.
