IP0021, FV6020, UTP-1200

IP Phone Supporting IAX2 Protocol

This phone is available from many distributors and apparently many manufacturers. I bought the phone form AstroHog and so far it seems to work fine. However, I am concerned that I seem to be unable to find the original manufacturer because I am unable to find updates to the firmware. However, the version I have has a fairly up-to-date firmware (by date) and so far there is only one minor annoyance (the ring in sound when you dial out is not the North American sound but instead a fairly piercing tone followed by a silence then it repeats) (You can change this: web interface -> Advance (sic) -> DSP -> "Signal Standard".)


The question mark is here because it is not clear exactly who manufactures this phone. I provided the links I found for completeness. Someone removed one of the links for spamming (That is not the case, I have a watch on the page and both links are a part of my original edit).
