Know how WiFi calling works with internet business phones, its key concepts, perks of taking business calls over WiFi, and its main limitations.
Business owners worldwide are buzzin' about WiFi calling! This crazy cool tech lets you chat over the internet instead of cell towers.
No more "Can you hear me now?" fumbles when the bars dip. WiFi calling brings crystal clarity wherever you've got broadband. For biz pros, it means no static on important work deals when you're offsite.
Hook it up to your internet phone system and voila! You’ve got connections from conference rooms to cafes. How does it work? We’re spilling all the details you need to know.
Alright, let’s first examine the answer to the big question you might have - what is WiFi calling?
The least techy way to describe it is that WiFi calling refers to the capability to make and receive phone calls over a WiFi internet connection rather than the traditional cellular network. To get a little more techy though - it works by routing your call as data packets over the internet when connected to a wireless network, instead of using a cell tower. This allows your smartphone or mobile device to seamlessly make or answer calls and texts over any WiFi access point, public or private.
With WiFi calling enabled, when you place a call, your device will detect if you have a WiFi connection available. If so, it will route your call through the WiFi network's internet protocol (IP) infrastructure. If outside WiFi coverage, your call defaults back to the regular cellular infrastructure. The technology bridges both networks for maximum flexibility.
WiFi calling opens up tremendous possibilities for making and receiving phone calls. It provides an alternative way to connect when cellular coverage is weak or unavailable, saving you from constantly dropped calls and dead zones. For businesses, it supercharges mobility and reach.
Opting for WiFi calling offers several excellent benefits, especially in business contexts:
Superior Call Quality
WiFi calling results in significantly clearer voice calls in locations where cellular connectivity is usually spotty or inconsistent. For customer calls, better audio quality prevents miscommunication.
Enhanced Workplace Mobility
Inside some large buildings, cellular signals can be weak or inconsistent. WiFi calling provides a reliable alternative for on-premise mobility.
Cost Savings
When traveling internationally, WiFi calling lets you avoid exorbitant roaming charges by routing calls over local internet connections. It also reduces long-distance calling tolls.
Expanded Range
WiFi calling enables connectivity from extremely remote locations with internet access but no cellular towers, like maritime vessels, remote tourism sites, and some airplanes.
Reliability
Cell networks can get congested, but WiFi calling provides a robust backup option to maintain important business calls anytime, anywhere.
For today's mobile and distributed workforces, WiFi calling delivers superior connectivity, savings and flexibility - giving businesses a true competitive edge.
Let’s go down the tech rabbithole for a moment and explore exactly how WiFi calling converts your voice into data packets and routes calls over IP networks:
First, you initiate a call on your WiFi-enabled smartphone or device. It checks if WiFi calling is active and a network is available.
Then, your phone digitizes your voice into Internet Protocol (IP) packets, compresses and encrypts them for transmission. This process is called codec encoding.
Packets are sent from your device via the WiFi network to a provider's internet telephony servers. This connection is encrypted for security.
Meanwhile, servers authenticate your device's access credentials and route the call over the IP network to its final destination. This may be another WiFi-enabled device or a regular phone number.
Finally, at the receiving end, packets are decompressed and decrypted. Your digital voice data gets converted back into analog voice signals for the recipient.
This all happens in milliseconds! The process leverages internet protocols like SIP, RTP, TURN and STUN to handle trafficking, quality of service, and network traversal. Pretty cool how it enables voice over data networks, isn’t it?
Integrating WiFi calling capabilities into cloud-based internet phone systems for business unlocks powerful flexibility. Instead of relying solely on cellular networks, enterprise Voice over IP (VoIP) platforms like Ring4 can route calls over WiFi when cell service is choppy or nonexistent.
This means sales teams can reliably make calls anywhere the internet is available. Support reps can assist customers without dropped calls as they move around offices. And, remote employees gain enhanced connectivity from home or on-the-go.
With the ability to seamlessly switch between VoIP apps and native dialers based on network availability, WiFi calling maximizes reliability.
Activating WiFi calling is straightforward if your mobile device supports it. Follow these tips:
- Update your phone's operating system to the latest version.
- Sign in and connect to a trusted WiFi network (This step is critical for security.)
- Go into your phone settings, select "Cellular" or "Networks" and find the WiFi calling option.
- Enable WiFi calling and toggle on any additional settings like "WiFi preferred" to default calls to WiFi when available.
- Add an emergency address that will provide location context when dialing 911 over WiFi.
- Reboot your device and test WiFi calling by placing a call with airplane mode enabled.
With WiFi calling configured, you can now enjoy smooth connections anywhere you have a wireless internet signal.
To optimize call quality over WiFi networks, Quality of Service (QoS) management is essential. QoS refers to techniques that prioritize voice and video traffic above other types of network data packets. Enabling QoS means your time-sensitive voice packets will get preferential treatment.
Without proper QoS, WiFi calling quality can suffer from delayed packets (latency), jitter, and loss. Choppy, robotic-sounding calls indicate subpar QoS.
Whenever possible it’s best to use a high-speed broadband connection, enable QoS or "gaming/voice" modes on your WiFi router to prioritize packets, and reduce bandwidth-intensive activities like streaming, downloads, or gaming during calls.
What devices work with WiFi calling? Here's a quick compatibility overview:
- Most modern iOS smartphones from iPhone 8 or newer. Make sure your iPhone supports VoLTE as well.
- Android phones from popular brands like Samsung, Google Pixel, OnePlus and Nokia running Android 9 or higher. Verify carrier support.
- Many wearables like Apple Watch when paired with your iPhone.
- Windows 10 laptops and tablets using the WiFi Calling app.
- Certain Alexa devices through Alexa Calling integration.
Even some airplanes and cruise ships now offer onboard WiFi calling! Check with your carrier and device manufacturer to confirm compatibility. And don't forget desktop and mobile apps integrate beautifully for unified business communication.
Concerned about privacy on WiFi calls? Look for VoIP service providers who keep security top of mind to protect your voice data in transit.
It’s also important to use WiFi calling only when you can connect to trusted, validated WiFi networks.
For added peace of mind, you can also choose to use a trusted VPN on public hotspots. Plus, for an extra layer of security, you have the option to modify your location on your iPhone while connecting to public hotspots. With enterprise-grade security baked in, WiFi calling lets you chat and collaborate safely.
One of the best perks of WiFi calling is seamless connectivity anywhere in the world with WiFi access. Here are a few tips for making calls with WiFi while traveling abroad:
WiFi calling enables keeping close contact with your team and customers from anywhere globally. You can be productive on-the-go without worrying about outrageous international usage and roaming fees.
We’d be remiss if we didn’t share that WiFi calling does have a few limitations to note. For example, call quality is heavily dependent on the speed and stability of your WiFi connection. QoS optimization is key.
You should also know that handoffs between WiFi and cellular can sometimes briefly drop calls, so aim for stable WiFi - especially for those critical calls you don’t want dropped!
Finally, emergency 911 calls over WiFi require an updated registered location to route properly. So, be sure to register your location for emergencies.
In our opinion, the immense benefits of WiFi calling easily outweigh these manageable drawbacks for most enterprises and workers on-the-move.
WiFi calling allows making voice calls and sending texts over WiFi internet instead of solely relying on cellular networks. Not only will you enjoy crystal clear call quality, but you can prevent dropped calls from poor cell reception.
WiFi calling is especially helpful when traveling overseas - bye bye pesky roaming charges! It also integrates beautifully with modern cloud business phone systems to enable workplace mobility.
With WiFi calling, companies like yours can effectively connect with customers, partners and remote staff by maximizing uptime. And, since WiFi calling is built into most smartphones and business VoIP platforms, companies can experience incredibly flexible and reliable unified communications. The ability to make calls over IP data networks ensures voice availability even in hard-to-reach locations.
