Hello Guys,

today I tried to decode a q931 pcap file directly in a linux cli. I had
success and the result looks like this:

- -- SENDING ------- Packet number: 00001 --- SpanID: 1 ----------------
    Protocol discriminator: Q.931
    Call reference value length: 2
    Call reference flag: Message sent from originating side
    Call reference value: 0002
    Message type: RELEASE (0x4d)
    Display  'HK at FreeSWITCH'
        Information element: Display
        Length: 13
        Display information: HK at FreeSWITCH


- -- SENDING ------- Packet number: 00002 --- SpanID: 1 ----------------
    Protocol discriminator: Q.931
    Call reference value length: 2
    Call reference flag: Message sent to originating side
    Call reference value: 0002
    Message type: DISCONNECT (0x45)
    Cause
        Information element: Cause
        Length: 2
        .... 0000 = Cause location: User (U) (0)
        .00. .... = Coding standard: ITU-T standardized coding (0x00)
        1... .... = Extension indicator: last octet
        .001 0000 = Cause value: Normal call clearing (16)
        1... .... = Extension indicator: last octet


I think this helps server admins to get a much faster access to the
decoded packages on a pure server where they have no GUI and hence no
wireshark. tshark is needed for this of course.


regards
Helmut
