[asterisk-ss7] SS7-ISUP

[3LINK黃俊豪]

Hai Sir,
    I am using asterisk 1.6.2.24 with digium runnig SS7 protocol. Now I face a problem, while my carrier send me CON(connect message) in Message Type, I will get an Unknow in Message Type.
    There are two situation : 
    (1) If a call receive Message Type like these -- IAM -> CFN -> ACM -> ANM -> Unknow
            the Unknow should be CON
            will get these errors messages -->  chan_dahdi.c:12604 dahdi_ss7_error: !! Unable to handle message of type 0xd
                                                             chan_dahdi.c:12604 dahdi_ss7_error: !! Unable to handle message of type 0xd on CIC 6
            But the call still goes smooth.

    (2) If a call receive Message Type like these -- IAM -> CFN -> Unknow -> REL
                    the Unknow should be CON
              And this call will silent in caller side.     

   
        I also using asterisk 1.8.14.0, digium hardware include echo cancelation (1TE820BF). But we still heard some echo.
        Is that anything we need to turn?

Thanks a lot
