Verizon and T-Mobile have switched their networks to IPV6. This BETA version of the 3CX client for iOS supports IPV6, including IPv6 to IPv4 (NAT64) mappings.

We would like to invite you to sign-up as a pre-release user for our iOS client to get the latest builds before the official release. Users that are already subscribed to the beta program do NOT need to subscribe again.
If you would like to take the new iOS client for a test run, follow these steps – make sure you use your Apple ID email – and you will receive an email once a new build is ready to try. Please note that we upload the new Test Run subscribers to Apple at intervals so the process is not immediate.
