ePDG for Mexico

[andres_arizpe]

Hi,

I'm trying to locate the ePDG FQDN to configure WiFi calling in Mexico for my vSZ but it is not working.

According to a recent presentation by Juan Brave, Ruckus SE, the format is:

epdg.epc.mnc020.mcc334.pub.3gppnetwork.org

Where 020 is the carrier ID (Telcel in this case) and 334 is the country code for Mexico (according to https://www.mcc-mnc.com/). However I get an "Unknow host" erring when I try to ping it.

I've tried with other carrier codes in Mexico and get the same error. Google search did not provide any relevant information either.

Has anybody gotten wifi calling to work in Mexico or at least has the correct ePDG name?

Cheers,

Andres

Hello @andres_arizpe, 

EPDG can be traced from the packet capture, initiate AP PCAP from SZ while client trying to reach DNS for EPDG resolution to initiate WiFi calling.
