    I'm trying to create and extension for 2201 and I get the error:

    • Given DN number cannot be used
    Doesn't seem to be a system extension... Any ideas?

    Hello @msnyder

    what version PBX are you using? also is your PBX set to 4 digit extensions? can you create the 2202 extension or do you get the same error?

    Is there a SIP ID used somewhere that matches? What happens if you dial that extension number? Check the 3CX Activity log if the call appears to go somewhere.
