whatsappIn Febuary, WhatsApp announced they would be adding voice calling services to their popular messaging app in the second quarter of 2014, but that time period came and went with no such addition.

WhatsApp’s CEO Jan Koum has come out and said that they are targeting a first quarter 2015 date to add voice features.

He revealed this in a presentation at the Code/Mobile conference this week.

He admitted that the development team has a number of technical hurdles to overcome before launching voice features. One of them is that the app itself doesn’t have access to the microphones on some smartphones.

WhatsApp was recently acquired by Facebook, but Koum said this week that he doesn’t think WhatsApp will compete with Facebook Messenger, which also has free voice call features via WiFi.

While Facebook is designed to work on both mobile products and desktops, WhatsApp is designed to work just on mobile devices, so any voice messages will go to a user’s contact list.
