    If the GS set can call other extensions, and the only issue is with external calls, then there may be a problem with outbound rules, and specifically how they deal with the number(s) being dialled. This should affect calls from all sets if they are dialling the same number(s). Check the 3CX Activity Log.

    Hello @SBDTel

    Like leejor mentioned, can you call other extensions or is the issue only with outbound calls?
    Also is the grandstream phone manually provisioned as a remote extension?
