I have Meraki AP's connected to Meraki switches and have two SSID's configured. One is guest and one is internal. The guest network is configured for NAT mode with PSK and is only filtering Video and Music, no filtering on the internal network. We are unable to make or receive any phone calls while connected to the wireless network.
I thought it might be a FW issue for the internal network but the guest network is not working either and it does not use our firewall.
Wi-Fi calling is enabled on their smart phones as they say it works for them at other locations.
I will try to place a phone in airplane mode and see what happens.
The best tip I can give you re Wi-Fi calling is to ensure that your mobile date setting on your phone is set to DATA only and NOT Voice + Data.
On an apples go Settings / Mobile Data / Mobile data Options / Enable 4G - Set this to Data only.
You will also need to educate users so that they understand when talking on a call using Wifi calling, if they move out of range of the Wifi calling it will drop the call as it is unable to hook the call to the local mast in the area quick enough.
Hope it helps
With phone calls you mean calls using the regular phone mechanism in cell phones right? So I assume we're talking about WiFi calling. I suppose calling works when you disable WiFi calling on the devices? Is this on Android devices or IOS devices? Are you experiencing this issue with all providers?
Yes, Wi-Fi calling using the regular phone mechanism on the cell phones. This specific location is located in a basement that has very poor cell phone service. I am being told that it is both IOS and Android devices but I will confirm that. I can't specifically say right now if it applies to all providers but I will investigate that.
The problem appears to affect both Android and Apple and does not work even when the phones are placed into airplane mode.
Any other suggestions?
The only thing being blocked on the guest network is video and music. The firewall is a checkpoint firewall.
I assumed that the guest networks traffic was tunneled past the firewall to the meraki cloud and would therefor not be subject to the firewall. Is that not correct?
That is not correct. The cloud connection is an out-of-band management connection. Your user traffic is never sent to the cloud.
This also started affecting me today. Some of my SSID's work for ATTWIFI some do not.
all are bridged. I did not make any changes to the SSID but something else in MDM might have kicked .
we can no longer make wifi calls
Any one have and resolve this problem
I have had this problem very Recently, where Wifi calling would be un predictable. WiFi Calling sets up a type of VPN connection back to the provider. so Content Filtering or any type of Firewall Rule that would block ipsec or anything blocking or Filtering port 500, 4500, 5061 will break wifi calling. (For example with PFSense you have to Enable PF scrubbing). I have SSID with Internal NAT and my Wifi Calling is working. Issue was my Router.
Is your Router a MX or another Device?
Is this due to a recent change? I've been using wifi calling with Meraki MR42's for a year now (currently running 25.13) but have not heard of it not working anymore.
Guess I'll investigate.
My router is set to upnp, but I can control the traffic. Earlier last year I did notice such an issue, so it’s not a problem with router I think. Besides I setup on all my iPhones FastLane profile through MDM to ensure the voice and video has always highest priority. I don’t use Meraki router I use instead UniFi router.
@Felippe Is the issue reproducible on demand? if so, I would recommend taking a packet capture on the wired port of the AP. Take a not of the time you got disconnect from wifi calling and check the frames for that particular time. This will give you some visibility if it is the AP or the router.
I suspect the issue is with the router but the packet capture will confirm the behavior.
