Especially now that WhatsApp (recently acquired by Facebook) tries to hijack voice calling already. Even if you press the phone number in the WhatsApp contact details.
This was a major annoyance for me because I was used to abusing WhatsApp as my address book and the voice call quality with WhatsApp is often atrocious (plus it uses up my phone's very limited data plan).
