Looking for a PBX system that uses cell phones as extensions.

looking for the perfect telephone headset for conference calls

• I'm in a different location than most of my co-workers and spend a lot of time on conference calls. I have a problem with different participants being at different volume levels. I'm constantly adjusting the volume but still end up missing what the quieter participants say (generally those calling in using office phones in other locations) and getting my ears blasted by the louder participants (generally those calling using their personal cell phones). What I need is a headset with that will normalize the volumes of the different callers. Is there such a thing? Any recommendations? Other things that may be relevant: The headset would need to connect to my desk phone (Aastra 9133i) and I should be able to still use the handset when I prefer. Our office uses a VOIP system that no one likes but that will not be replaced anytime soon. I do not need to move around while on the calls; it's fine if I'm tethered to the desk by a cord. A good quality microphone is also desirable so the rest of the call can hear me clearly without it echoing their voices back to them. I don't have a specific budget -- just an admonition to not go too crazy.
