It is not all finished for Windows Phone, although Windows 10 hits hard, it seems that development is not left behind definitively. Slack is one of the most powerful and popular productivity and group apps on the market, now Slack will include the ability to make calls, and has also reached Windows Phone. Currently, like hundreds of other applications, Slack is in beta, however, it seems that the performance on Windows Phone devices is not all bad. Windows Phone enthusiasts will receive this news as refreshing and welcoming.
The experience of calls through Slack for now is not the best, but it works which is the important thing. We simply have to click on the phone button that appears under the profile of our group partner. A voice chat will automatically open with him. Definitely, if it works as it should and becomes popular, it can be a major blow against Skype for Business, Microsoft's project for business based on Skype. The development team has been questioned about the arrival of this feature to Windows Phone, and the response from Slack's official Twitter has been:
We are working on it. The Windows Phone application is now in Beta, so we hope to improve it little by little, the road is going to be long.
Therefore, they do not know when, how, or where, but the calls from Slack for Windows Phone are going to come. Hope is the last thing you lose. Windows Phone development and share are inevitably falling, and it seems that it will only be a matter of time before Microsoft announces its stoppage, at least if they do not hit the table. The reality is that the developers have not approved the initiative and it has been a shame. The system was fluid and efficient.
