We have an add-on module which allows you to tie phone call tracking and conversions in with Google Analytics from PPC, banner ads, organic rankings, forums etc. http://www.clickthrough-marketing.com/phone-call-tracking.php

Does anyone have any other add-ons for Google analytics which help to measure similar calls to action, conversions, marketing actions and results etc which they use for clients?

Thanks

there are a few companies offer phone tracking that can be easily added to GA - CallingU is one of top of my head

That's great information i did'nt knew that. Got to try this one.
