Hello and thank you for your help!! I purchased this Cortelco 7150 five months ago from my telephone company. I am having a lot of people that I call, telling me that they can't hear me. I was wondering if there is any way to cut the outgoing volume up so my family and friends can hear me when I speak to them? Thank you very much!!! Sincerely, Sandra C.
