    Hi
    we have setup in a remote office 6 users connecting to a google hosted 3cx platform using soft clients.
    All working fine but the users then asked for deskphones.
    we have received the new Yealink T42s handsets ( x3 ) and have connected them to the the POE switch and they power up fine.
    I have run through the Add phone section and applied the details to one handset. I applied the manual config for Account 1 and the Auto provision details and then the phone tries to register. And this is where it gets stuck. the phone will not register.
    I have the following ports opened.
    tcp/udp- 5060
    tcp/udp- 5061
    tcp/udp- 5065
    tcp/udp- 5090
    tcp-5000
    tcp-5001

    I have run the firmware upgrade and factory reset the phone. any suggestions?
    As a side note from about lunchtime the soft clients stopped displaying the preference information and call history. is this coincidence? the soft client outside of that office appear to be working fine?
    TIA
    Greg

    Hello @Greg.wilmot

    Please try to provision the phones using the supported method documented here: https://www.3cx.com/sip-phones/yealink-t4-series/
    Also make sure that the option "Disallow use of extension outside the LAN" under extension settings / Options is not selected as the phones will not register. More details on how to configure the remote phones can be found here:
    https://www.3cx.com/3cxacademy/videos/intermediate/configuring-remote-extensions/

    Also check your IP blacklist as the PBX might have blacklisted the remote sites IP due to registration attempts from the IP phones. You can find it on the Dashboard under the PBX status column.

    Thanks very much. a combination of the ip blacklist and the "Disallow.." option and using the correct uid and registered id and i have them all working.

    easy when you get all the ducks in a row!

    thanks
    Greg
