Magicall does this and is significantly more powerful in terms of customization, features, and probably even user friendliness. This comes at a cost however, since it isn't freeware, but a one-time payment has saved me from 707 phone calls since October so it was worth it in my case.

It also supports SMS trigger email checking for the most battery efficient realtime email service (compared to activesync push and interval polling).
