Hello,
What does the following stat mean when you run the " openserctl moni "
sl: received_ACKs = xxxx
I did some digging and I got the following explanation... But am not
sure if this is an
error in operser or an error on a message received by openser or what?
" sl: received_ACKs - number of received ACKs due sending negative
replies. "
when you send a negative reply (code >=300), the calling party
sends an
ACK. This ack is filtered by sl module (does not get in config file).
This statistic counts them.
Typical case is authentication of calls or registration. The auth
modules use sl to send back the challenge (401 or 408 replies).
Cheers,
Daniel
