E-mail is far more convenient than the telephone, as far as I'm concerned. I would throw my phone away if I could get away with it.- Tom Hanks
After iOS5 came out, the location field became a place where text was tappable to make calls or copy/paste, but many of my coworkers don't include the conference call number in a way where it will dial both the phone number and then the conference call entry code. For a while it was okay, where I could temporarily memorize the 6-digit entry code and then tap the number, but working recently switched to a new teleconference system that has a 10-digit entry code. I'll admit that I cannot temporarily memorize 10-digits.
I fixed this with a trivial little web app. Behold conference dialer! It has two text inputs - one for the phone number to be dialed and one for the entry code for the conference call. This way, when I get a meeting invite where the dialing is not properly formatted for the iPhone to recognize, I just copy-paste the phone number, copy-paste the entry code and hit the dial button. Simple. Elegant.
I added some local session HTML5 stuff so that it will remember the last number and entry code you had filled in. I was thinking about maybe having it remember the last 10 numbers you called or some such. We'll see where it takes me.
