Thread: SIP error 401 on successful calls

    Default SIP error 401 on successful calls

    I am seeing 401 unauthorised errors in Quadro logs but calls complete successfully. PBX is Quadro 16x, handsets are Snom 300. Log extract as below. Can anyone shed any light on possible causes?

    Thanks
    Patrick

    Hi

    After receiving invite Quadro requested Autorization from Phone ,thats why you see Unauthorized in logs and after autorization makes call, its normal sip messaging procedure.
