Thank you for providing your state name, jpri.
Your question is not a
real easy one to answer. Because your business is nationwide, you have 50 different states with different laws to consider, and you have federal recording laws. Whether a terms and conditions agreement located on a website would be considered sufficient consent to the recording of later phone calls is something that I can't tell you. I think it could be argued that it isn't.
Following are some links to information on recording laws that can perhaps guide you - but I recommend you discuss your particular business with an attorney in your area to better ensure that your business operation will not inadvertently violate any recording laws.
From the Digital Media Law Project, "Practical Tips for Recording Phone Calls, Conversations, Meeting, and Hearings" (
http://www.dmlp.org/legal-guide/practical-tips-recording-phone-calls-conversations-meetings-and-hearings):
"The best way to document that you have obtained consent is to record the consent along with the phone call or conversation."
From the Digital Media Law Project, a legal guide to recording phone calls and conversations, (
http://www.dmlp.org/legal-guide/recording-phone-calls-and-conversations): "Regardless of whether state or federal law governs the situation, it is almost always illegal to record a phone call or private conversation to which you are not a party, do not have consent from at least one party, and could not naturally overhear."
18 U.S. Code §2511:

From the Reporters Committee for Freedom of the Press, "The FCC's role" (
http://www.rcfp.org/reporters-recording-guide): "The FCC requires that an individual notify the other parties to a call before using a tape recorder in an interstate call. The rule requires that the individual either get consent from all parties before making the call, notify the participants at the beginning of the recording, or use a 'beep tone' that is repeated regularly throughout the call."
You can click on the different "Reporters Recording Guide" topics on the left hand side of the Reporters Committee for Freedom of the Press page for additional information. There is, for example, a state-by-state guide to recording laws.
Again, although I understand that you will be getting consent from the plumbers and the customers through a terms and conditions agreement, I am not sure that this will protect you from potential legal actions should someone object to the recording, so I think this is something you will need to review carefully with an attorney in your area. I recommend that you have phone notifications of the recordings for each call (with oral consent given to the recordings), though, because I believe that will be legally safest for you.
