This is the chosen one! – Media5-fone SIP VoIP Softphone Review
I tried all the recommended ones. The ones like BRIA and ZOIPER (which you pay for) and they are just no match for this app. Those sound like I'm in a toilet using a foam cup and piece of string (broken) and this app makes me sound like I'm on a hard line telephone even when miles from the office. And it's free - well I'm using the free version and it ROCKS!
