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.
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?
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.
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.
