Analog telephone to SIP
PeteMc:
Hi,
I'm hoping someone here may have an solution to an issue I'm having.
We apparently have high interference in the 1.9 GHz range, so standard cordless phones are useless more than a few feet away from the base station. But there's no issue with our 5 GHz WiFi.
I'm looking to see if there are phones that use 5 GHz WiFi and a way to convert analog lines to SIP (or whatever) to use with these devices?
Anyone have any suggestions on how to do this or where else to go ask?
Thx!

My understanding is that the 1.9 GHz channels used by DECT 6 in the US are reserved for voice communication. Why are you suffering high interference?
PeteMc:
Yes, it is the reserved band, but interference is interference....

Like drgeoff said, the DECT 1.9 GHz band is reserved. There shouldn't be any legal RF interference. You can complain to the FCC if someone is polluting that band; otherwise, you have a problem with your own DECT equpment.WiFi is terrible for voice calling. WiFi just isn't designed for low-latency, high signal-quality use as needed for voice. As far as I know, almost every vendor that tried to sell a "WiFi phone", withdrew the product.If you're intent on using WiFi, any modern Android phone can use a SIP client like CSIPSimple or X-Lite or Bria, configured with SIP credentials from a SIP VoIP service provider. You can decide for yourself if you are satisfied with the call quality.
Prior to DECT, Uniden (and that other cordless phone company, name escapes me) and Panasonic all sold 5.8GHz cordless phones. They worked fine, and that band isn't impacted by interference from WiFi. If you can still find them, that would be your best alternative.

I would try to find the interference. It could be a sign of serious problems to come.
