Buying Guide: Key Purchase Considerations
- Call volume and lines: For multiple lines, consider devices with 2–4 FXS ports or multiple SIP profiles to handle concurrent calls.
- Network integration: If you need built-in routing and Wi‑Fi, choose combinations like modem/router with VoIP support or ATA devices paired with a separate router.
- Security and QoS: Look for SRTP support, VPN options, and QoS features to prioritize voice traffic and protect call privacy.
- Provisioning and management: Automated provisioning, TR-069, XML configs, and remote management ease deployment for small teams and offices.
- Ease of setup: Plug-and-play adapters are suitable for simple home setups, while multi-port gateways suit more complex office environments.
- Compatibility: Ensure SIP V2 support and PAP2T or similar compatibility if you rely on legacy phones or specific providers.
- Mobility and access: If employees work remotely, consider devices with AP mode or portable Wi‑Fi functionality for flexible networking.
- Support and warranty: Renewed devices can save costs but verify vendor support and return policies for peace of mind.
