WhatsApp sent out an update to its iOS application earlier this week, which included support for the instant messaging service’s new voice over IP feature.
It warned in the change log on Apple’s App Store that the feature could take a while to become active for all users.
“WhatsApp Calling is rolling out slowly over the next several weeks,” the update notification said.
Other new features in WhatsApp 2.12.1 for iOS include an iOS 8 share extension, a quick camera button in chats, editing contacts in WhatsApp, and sending multiple videos at once with the ability to crop and rotate them before sending.
One fortunate MyBroadband staffer had the feature enabled on his phone, which means we were able to take it for spin.
Our first test, trying to call the iPhone from an Android device, proved unsuccessful. However, the iPhone was able to call the Android device.
Further testing revealed this was probably because we were running a newer version of WhatsApp for Android (2.12.19) than what is available in the Google Play store.
After downgrading the Android version of WhatsApp to 2.12.5 it was possible to call the iPhone from the Android device.
When testing over Wi-Fi, the quality of voice calls were generally good after the first few seconds. However, during the first few seconds of the call there was a lot of latency.
Thanks to Kevin for his help testing iPhone WhatsApp calling.
