I'm pretty sure that my EMTA from Spectrum is compressing voice to G.729, which seems to be the norm. Because I do a lot of dial-up modem work, I asked them if they would take it down to G.711. Of course, I might as well have asked if I can get wine running from my faucets. Anyway, after about an hour, I reached someone who told me that it simply can't be done, but that I can purchase my own router that will do it. I don't believe this.
I logged into the router settings and of course there's nothing on the user side, however there is a password-protected side for their technicians to use in order to access advanced settings. Does anyone know if they are telling me the truth or if I should just seek an alternative?
