• Description of the problem, include any visual indicators on your phone
Can’t make or receive wifi calls on home wifi since switching ISP to Spectrum (formerly Charter). Phone just says “calling on wifi….” and never connects. This is with 2 phones, a Moto X 1st gen and a 2nd gen (RW 2.0).
Wifi still works for web, data, texts, anything else.
Can still make calls on other wifi locations.
• Name of ISP (Internet Service Provider)
Spectrum (formerly Charter)
• Type of service, i.e. DSL, cable, satellite, broadcast
• Router brand, model, and version (all the numbers and letters from the model designation on the nameplate)
Sagemcom F@ST 5260
• Firmware revision of your router if you are able to find it.
Hardware Version 1.0
Software Version SG9C120074
I’ve been trying to work through the “Maximize your wifi community guide”, but I cannot figure out how to do this suggestion:
"Disable SIP ALG (Application Level Gateway) … Check router’s configuration to ensure it does not have SIP or NAT ALG enabled"
I cannot find anything about this in my router settings. I can find a section called Firewall, in Access Control, where it appears I can create some sort of custom rules, and I can find SIP in a dropdown list. But I don’t know what to do from there (Protocol? Port? Action = “reject from both way”?). I don’t know anything about these; to choose a custom rule, I would seem to be switching from “Level = Low” to “Level = custom”, and there’s already a list of 15 or so rules in “custom”.
Any help would be appreciated. We’ve been with RW for 4 years. Our phones are old, and now we can’t make calls from home without turning off wifi. I tried a tech support ticket, but they sent me here.
