I was talking to one of our agents the other day about the frustration of bad phone numbers and bad e-mail addresses and it occurred to me that there must be a better solution to this problem.
The one solution I know that other's here have implemented is to send an e-mail verification with a clickable link to verify the e-mail. The problem with this is that we risk losing the user if they have to switch back to their e-mail account and/or wait too long to get the e-mail.
A new solution is real time verification technology.
1) Real Time e-mail verification... this can check the address for validity in various ways (ie does the domain exist). Here are two of the leading vendors for this:

2) Real Time telephone verification... this will call the number and verify using a PIN code.

I'd be curious to hear what others think about the viability of implementing either of these. Particularly, how do you think users would react to telephone verification?
