WiFi calling is a lifesaver when your cell phone network is inoperative. It is a great alternative plan to have if you want to make yourself available whether for work or for other personal reasons.
WiFi calling through mobile phones has been common in the last few years. Despite being a familiar feature on devices of Android and iOS, users do not realize that it is incapacitated by default.
Hence, you may face WiFi calling error when trying to make calls using WiFi.
You can optimize your experience of WiFi calling by following the methods below. As per your WLAN architecture and hardware, the steps may vary slightly.
Wireless density implies a number of WiFi gadgets that one needs to plan to support within the coverage area. As WiFi calling provides end-users various benefits covering better strength of the signal and enhanced call clarity, more users will tend to join WLAN.
Your WLAN design would bounce in this wireless density. In addition, it would place wireless connecting points close, which will allow better administer the rise in connected devices.
Ensure that your internet plan has a per WiFi call bandwidth of 12Kbps-72 Kbps. Well, this number may not be a big one, but it can rise up quickly when you start taking dozens of simultaneous calls over the WLAN.
Having QoS set up on the wired LAN does not imply it is also configured on the wireless LAN. Preparing QoS policies for voice enables various WMM services to enhance voice communications when congestion occurs in WLAN.
Most of the organizations advise WLAN vendors to enable technologies allowing seamless roaming on a WLAN between wireless access points. This means adopting IEEE 802.1X, IEEE 802.11k & 802.11v for faster-authenticated roaming techniques and for providing assisted roaming respectively.
One of the easy methods to check that your mobile is having the best WiFi connection for voice communication is to drive them for connecting to the band of 5GHz instead of 2.4 GHz. There are various reasons for this such as:
There are also various methods to drive WiFi calling gadgets to link with 5 GHz. Two of the most important are:
Lastly, restart your device after it is rebooted to check if the problem persists.
