Wi-Fi Calling Poor Performance

DBurritt — Thu, 16 Mar 2023 15:17:47 GMT

Hi All,

We have 5 AP230s and we are experiencing consistently bad performance on Wi-Fi calling. When Wi-Fi calling is enabled, it works intermittently. Calls will sometimes go through, sometimes not. Calls going out will often work for a minute and then cut out to cell. Since we have little to no cell, the calls then drop.

We have tried enabling voice enterprise and it seemed to improve the situation, but not remedy it. We've tried quality of service settings with voice calls as highest priority, and that also didn't remedy the issue. We have 100x100 fiber so we have a very solid connection. All of our desktop phones run over the wired network with no issues.

Any and all suggestions are appreciated. We have about 15 people who work in the building with varying devices and they all experience this issues.

Thank you.

Hi,

Are the client devices Apple iPhones?

Maybe check the following articles:

I do not know what troubleshooting you have done so far, do you only have issues with VoIP traffic on the Wifi?

Is there any interference reported by the AP's. occurs the issue when you roam from one AP to another AP?

Are the calling devices connected to the 5Ghz wifi or the 2.4Ghz frequency?

Thanks!,

Kind regards,

Sjoerd

Hello,
A few ideas and a few questions!

AP Firmware version?
Are the devices static or roaming through the building when on calls? Additionally if you look at a client in client360 can you see it roam at the approx time of a call dropping?
Presuming these are mobiles that are connected to the WiFi, do you know what they're connected to (2.4 or 5GHz)? - may be worth changing to 5GHz only if possible to see if that makes a difference.

Do you have any load balancing or band steering enabled in radio profiles? Any high utilisation of APs/Airtime/Interference observed?

Hello,

Thanks for taking the time. I'm a librarian, primarily, so pardon my ignorance on some of these issues. The firmware says current, but this is listed as well:

IQ Engine 10.5r3 build-278650

I'll check the client roaming next time there is a wi-fi call. I thought that may be the case, but since a lot of calls aren't even making it to the device(straight to VM), I was hesitant to think this was the case.

I'll disable 2.4ghz to see if it makes a difference, but the devices should be on 5Ghz.

No particularly high utilization during these time periods, it often happens before we open to the public so it's just about 10 staff members. We enabled QoS settings and prioritized voice traffic. It seemed to have made a small difference, but not enough to have a meaningful impact. And since the issues are intermittent it is hard to tell whether it even made a small difference.

Thanks for your thoughts and I'll definitely keep a look at the roaming issue/disabling the 2.4ghz band.

Thanks Sjoerd,

Some of the devices are iPhones, but I think that's just an artifact that we are primarily iPhone users here. I use a Galaxy S9 and I have a colleague running android as well with issues.

The WiFi works mostly fine, other than some issues when staff play games during their breaks. Our wired VoIP works flawlessly.

I'm not sure how to check for interference when roaming. I'm a bit new to the WiFi world.

Thanks for your help and thoughts!

Hi Ash,

I went ahead and created a separate SSID to test on with just 5ghz. Testing on my device it worked significantly better, except when I roamed and then it was about 5 to 10 seconds before it was restored. I didn't think it would be something so simple, but you seemed to have really hit the nail on the head. Thank you!

Hi there,

It sounds like you’ve done a thorough job troubleshooting the AP230s and prioritizing voice traffic. Since your wired phones are fine, it seems the issue is isolated to Wi-Fi calling on those APs. A couple of additional things you could try:

Check for AP firmware updates – Sometimes Wi-Fi calling instability is fixed in recent firmware patches.
Band steering and load balancing – Make sure the devices aren’t switching excessively between 2.4 GHz and 5 GHz, which can drop calls.
Device-specific settings – Some phones handle Wi-Fi calling better with certain VoIP configurations enabled.

Also, for teams needing remote communication solutions while troubleshooting hardware issues, I found tools like Truecaller apk useful for managing call reliability and seeing incoming call quality on different devices. It’s not a direct fix for APs, but it can help monitor call behavior across multiple phones.

What controller or management system are you using for the AP230s, and have you checked if there are any roaming or band-steering issues when devices switch between access points during calls?

What is your current AP configuration for band steering and roaming (especially 5 GHz preference), and do you notice if the call drops happen when clients switch between APs or stay connected to a single one Errors and solutions of Truecaller?

A lot of people forget to not only have a VLAN for VoIP, but to configure the network switch for voice. I know on an HP, I just have (within config) to put in "voice" command... just putting this out there as so many people forget it.. That command does a lot of QoS and needs to be in the VLAN for VoIP.
