WiFi Calling on IAP-105

Dear All,

 

we have a few IAP-105 installed and would like to use WiFi-Calling for our mobile phones. Current FW is 6.4.2.6-4.1.3.0_54915. I think FW must be at least 6.5. Is there anything else to be considered ?

 

Thank you  

Re: WiFi Calling on IAP-105

Hey, which implementation of Wifi Calling are you referring to? I can use the Apple Wifi Calling on my IAP105 running 6.4.4.8 without issues. You just need to allow UDP500 + UDP4500 on the assigned User Role.

Re: WiFi Calling on IAP-105

Thanks,

I would like to use WiFi Calling on Apple devices. I have now created a rule "Allow any to server FW for WiFi Traffic" but on my iPhone still "WiFi calling" does not appear.

At my home all fine.

 

Any help is appreciated.

Re: WiFi Calling on IAP-105

Hey, that should be it. The only other items which might be a problem is either an upstream device such as a firewall is blocking it, Wifi Calling isn't enabled on the device or it is not enabled by the carrier.


You can confirm if you receive a reply for the UDP4500/UDP500 packet by running the following on the CLI of the IAP. If you see a Y flag, then the 3-way hand shake has not occurred correctly.

 

#show datapath session | include XXXX (XXXX = IP of device)

Thanks,

 

WiFi Calling works fine at my home WiFi. It should be fine on the device and on carrier side.

 

IP of device means IP of the iPhone ? 

Re: WiFi Calling on IAP-105

That's correct, the IP which is assigned to the device. Do you have any further information on your network? Is there a firewall sitting upstream from your IAP's?

Re: WiFi Calling on IAP-105

thanks,

 

this is the "show datapath session output":

# show datapath session | include 192.168.51.35
192.168.51.35     17.252.92.30    6    49354 443   0    0    0   6   dev3        6744 SC
192.168.51.35     62.157.140.73   6    49384 443   0    0    0   11  dev3        352  SC

 

The IP address of the iPhone is 192.168.51.35.

 

Traffic from the APs will be routed to a FW. On the FW IPSec is allowed for in- and outbound traffic.

 

Re: WiFi Calling on IAP-105

Hey, there is no UDP4500/UDP500 traffic in that output so it's not attempting to establish the Wifi Calling?

Re: WiFi Calling on IAP-105

Thanks,

 

when my iPhone is connected to my WiFi at home I am getting an indication on the top of the screen "WiFi Calling".

 

I do not get this indication at the office. I assume that "WiFi" Calling is not active at the office.

Re: WiFi Calling on IAP-105

If possible could you share the User Role which is assigned to the phone? We can then check the firewall rules. 


Do you even see a UDP4500/UDP500 connection on your upstream firewall?
