I've had this discussion in the office and with some vendors, but no one has a solid answer, hopefully someone here does. What is the proper way to format a caller-ID here in the U.S.? Is it: +15705551212 or is it +5705551212 I've always seen it +15705551212, but as I understand it the country code for the US is 011, which to me would indicate you put 011-570-555-1212 as the callback number.

Just my .02, but 15705551212 (no +) is proper if caller is in U.S., 0115705551212 if not.

"+" means "this is an international call" and tells a cellphone, for example, to replace "+" with whatever is the international dialing code for the location where it's currently located. (In the US, that 011, so you'd dial 011-1-570-555-1212, which is the correct way to dial that number.)

"011" is what you dial from within NANPA countries to prefix a country code, so to dial Coumbia, for example, you would dial 011 57 xxxxxxxx...
