Hi all,
i am using libss7-trunk and asterisk-trunk to connect to a telecom
switch. I have been getting a lot of complaints from clients that
calls are not going through. My ASR is below 20%. When i analyze the
hangup causes, i find that more than 50% are Unknown:
Cause: Unknown (47)
Cause: Unknown (20)
Cause: Unknown (0)
Below is a debug of a failed call, I highly appretiate any help.
