    I have 3cx Server V12 running in the office with 3 extensions and one external ext using a samsung galaxy s3 LTE (4G version), 3cx installed latest apk for 3CXv12.

    3cx ports setup on my router / Firewall.
    When I am on the Lan the calls come through fine from the digital reception and I can dial all the different extensions and transfer calls fine, when out of the office on 3G the calls come through fine also and it all works well,but when I try to dial an extension from the s3 I always get the message "forbidden".
    The phone always says ON HOOK but not registered at the top when I am out of the office.

    I am using an isp that gives me a dynamic ip that refreshes every week so I have a dns service running, this is what the 3cx config on the phone is pointing to. (external pbx and tried local pbx) this is themovieworkshop.no-ip.biz

    If I try the wan ipof my pbx router it still makes no difference.

    Hope Kevin or someone who has had a similar experience can shed some light on this.

    Kind regards

    Because port 5000 is not forwarded at the PBX end, this is the Presence information , if you want to use it. It isn't necessary for making calls

    What does a 3CX log show for a failed call attempt. there may be an option that needs to be "adjusted" in 3CX. If you use a dynamic IP and make use of a DYNDNS service, that Domain name needs to be put into 3CX or it will reject calls with the domain included.
