  • Seamless operation with a wireless Internet provider, easily drives two old analog telephone devices that the former analog OTE used to struggle to "lift" simultaneously. The web interface offers "endless" settings and may initially seem intimidating, but most VoIP providers give detailed instructions or even ready-made configuration files specifically for this device. In my case, the setup took less than 15 minutes, including some of my own adjustments. It also has an audio configuration menu (via the telephone device), for cases where you temporarily cannot access it through the network, e.g., to set a specific static IP or to revert it to dynamic IP, etc.

    The device itself is okay but very limited instructions on how to use the so complicated user interface

  • Excellent! I've had it for 3 months now and it's flawless! The only thing that's a bit of a hassle, mainly for those who aren't familiar with it, is the setup, but even then, with the help of the company I'm with, it was set up perfectly!

    A very good solution for someone who wants to have a VoIP number but keep their analog device.
    All you need is a stable internet connection. It works flawlessly with Starlink, with no interruptions even during long calls.
    It is extremely customizable through the Web UI it provides, so you can easily tailor it to your needs. (The v2 version—the one I have—has a better, more user-friendly, and newer Web UI compared to v1).
    As for me, since I switched to Modulus VoIP, I found on their website how to set it up, step by step.

    Note:
    Those who have Starlink (which works with CGNAT) should enable the following setting to prevent calls from dropping during satellite changes:
    Port Settings -> FXS PORT1 -> General Settings -> Nat Traversal = Keep Alive.
    (Similarly for FXS PORT 2, etc...)

    Attention! Make sure to get the V2 version.

    In the V2 version, all firmware upgrades up to 1.0.5.5 must be done for those using it with Starlink.
    Update 2026: It works flawlessly with modulus and Starlink, highly recommended!

    The intertelecom supports it directly. For its price, the only thing I don't like is its slightly outdated menu in terms of sane defaults.

    It does exactly what it says very well. Based on the settings from the voip provider, it was set up in 1 minute and works without problems.

    I connected 2 devices - voip numbers, and the second device did not connect (register). After a phone call with the provider's company and some settings they told me to do, the problem still existed. After searching on the internet, the problem was with the sip port.
    For anyone who has the same problem, the solution is as follows (at least it worked for me):
    By configuring FXS PORT 1, you enter the settings provided by the provider. When configuring FXS PORT 2, you enter the settings again but use a different sip port. That is, if on FXS PORT 1 the sip port is 5060, on FXS PORT 2 you should set it to 5062.

    *2 years working flawlessly
