What I eventually came up with was a link that worked like this:

1-888-123-4567

This has worked on every phone tested so far, including Android, BlackBerry and some very clunky older phones. From what I gather, the structure of the link works like so:

WTAI references the Wireless Telephony Application Interface. The wp/ refers to the WTAPublic functions. The mc; is the makeCall function, and then of course you have the phone number. Similarly, you can do a link like this:
