Voici le service avec fibre optique ONT
Hello, I'm using an ISP-provided modem/router setup (Nokia XS-2426G-A and XS-2426G-B). Both devices don't work well in a bridge configuration, and changing their settings doesn't resolve the problem. I'm considering a bridged modem solution. I found an ONT model that might help: Huawei OptiXstar EN8010Ts-20. I'm currently using my landline, but I don't see an RJ11 port on the ONT or my router either. The ISP mentioned SIP Trunking, but I have a DECT setup (one base station plus one extra) and don't need a dedicated VoiP server. I also have a Raspberry Pi Zero 2W running a Pi-Hole, though it's not functioning properly because the modem isn't handling DNS. I'm wondering if anyone can assist with making voice work between my ONT and my own router. I have two networks: one for retail (store) and another for private use. My modem/ONT connects to a TP-Link Archer C7 in router mode, which I want to use for business. I also have a TP-Link DECO M4 for the private network. I'm trying to avoid double NAT and am unsure if setting the modem's DHCP range to 192.168.1.1 and then forwarding it to the Archer would achieve the same result.
This relies heavily on your ISP and VoIP service. Many providers restrict personal ONT usage. Those that allow it often hide the VoIP traffic, possibly routing it through a separate VLAN instead of the public Internet. While technically possible to set up your router accordingly, they may not guide you properly. A reliable provider should make SIP accessible over the Internet, enabling integration with DECT base stations or standard RJ11 adapters. Keep in mind that the Archer C7 might struggle with speeds above about 400Mbit, especially if hardware NAT acceleration isn't active.
Thanks for the update! Your ISP does accept "bring your own modem" setups. I spoke with them about Voice, and the employee mentioned SIP support—so it seems possible. When looking for a SIP converter, it’s not clear what you need. You might want a device that connects via Ethernet and has an RJ11 port, like the GO-Box 100 + Premium 100HX handset. It appears the Ethernet is directly connected to the phone, which should work well with your 250Mbps connection.
You don’t need to switch the wireless gateway into bridge mode. Disable the Wi-Fi on the gateway so your own router works properly. If the gateway includes a backup power source for VoIP, it should have one or two RJ14 connectors.
First, I’d consult your ISP about how they set up SIP. If it’s being sent over the web, you can verify it with a smartphone SIP app—typically you’ll be able to connect from multiple devices simultaneously (your router plus a phone app). Even though there’s a small chance the router might cause issues, it should at least show that connection is possible. There are adapters that convert SIP to RJ11, but using a DECT adapter for SIP to DECT usually works better. I discovered this the hard way: budget Gigaset handsets often have AAAs that degrade every year and their lithium batteries are costly. On the plus side, you can use your own phone’s handsets for more features. I own a Gigaset N300IP, though I’ve heard Yealink DECT IP base stations perform better. I learned this the hard way—affordable Gigaset devices sometimes lose AAAs after a year and their lithium models are pricier. In reality, I initially used other brands’ handsets and everything functioned fine, but remote access to base station settings and transferring contacts between devices isn’t possible. I also manage three SIP accounts with separate handsets, so you can pick the one you prefer for each call, which isn’t a problem if you only have one account.
