    Hello,
    I am using 3CX Phone System V12 (activated) with several phones. There is a problem with the Apple devices (iPhones and iPads) when used on 3G. The distant party can hear me but I can’t. The problem is solved when the phone is out of office, connected to a wifi or when it’s in office. I am using Tunnel and the “use 3G when available” option is enabled. There is no problem with android phones or with windows soft-phones. All devices use 3CXPhone 12. Can anybody help?

    The new version 12.1.0 seems to resolve the issue.
