No problem, Sailingnuts. The iPhone calendar can provide autmatic dialing of the entire conference number / access code in a single click, but in a slightly different format from the BB. When you create a new meeting, just add the conference line and participant code to the "Location" field of the invite, in this format:
800-123-4567,1234567#
The iPhone calendar will make the entire number a dialable link, and will pause 2 seconds for every comma before automatically dialing the participant passcode and pound key (add as many commas as you need to wait longer after the conferencing system picks up before auto dialing the passcode - no spaces between numbers or commas).
I work for a large company where there are tons of BB's, Droids, and iPhones, and we pretty much just add all 3 smartphone syntax's to every meeting so that participants can just click the one that their phone recognizes.
Hope that helps!
