🌐 Remote Configuration – Customer-Supplied Handsets & ATAs

We’ll remotely configure compatible third-party devices (≤1 hour; typically 30–45 mins).

The customer is responsible for compatibility — see your Contract Pack for supported models.

Important caveats:

Maximum of 1 hour configuration time per device (typically 30–45 minutes)
We may be unable to configure certain third-party models due to manufacturer restrictions or unsupported firmware.
More cost-effective when using hardware purchased from us, as compatibility and setup are guaranteed.

🔧 Preconfiguration of Handsets & ATAs

We’ll configure handsets/ATAs purchased from us so they’re ready to plug in.

Key points:

Only available for hardware purchased directly from us
Configuration matches your VoIP service settings
