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
