Guys....sorry I was expecting oobie to jump in here with some info on our current setup...guess he must actually be working for a change wink

Anyway, we are using cable modem on our end but I'm not sure what the other two sites are using...oobie would know that....
I am also not sure if we are using G.726 or not but I know that some of these same volume differences are showing up at customer sites that are only using pots lines and no VoIP at all. Just seems like the techs have to turn up the CO volume to satisfy the customer but then the intercom is too low due to the volume manually being turned down due to loud CO volume....I don't know it's a little bit frustrating to me. But hey....I'm just a salesman so what do I know?! :bang:
