Hello,

1) I am wondering what is the best practice to monitor if there are or
were problems with SIP calls on my Asterisk box. E.g. how about a
software that extracts all calls from the /var/log/asterisk/full (I
have permanently enabled verbose 10 and sip debug) log and tells me on
which of them were problems? Checking the logs manually is very hard,
but as SIP is a standardized protocoll, there should be tools doing
that for you? As an example, a person calling me recently got a 488
Not acceptable error as reply from my Asterisk box. Nothing came
through to my SIP phone, so I didn't know anything about the call or
the problems (which were on his phone btw). I would like to be
informed about such cases, know that there was a call to my Asterisk
box that made problems.

2) How about monitoring speech quality? E.g. sometimes it seems like a
packet is missing (I then have a short pause during the call), how to
monitor such things and create statistics out of this data?

So basically I want to monitor my Asterisk installation proactively
for reliability/problems and (speech) quality.

check asterisk testsuite
https://wiki.asterisk.org/wiki/display/AST/Asterisk+Test+Suite+Documentation

thereis scenarios for console sip client pjsua(from pjproject) which can 

perform speech quality measurement
