This is not clear to me. Contexts are not "restarted." What are you trying 
to log?

Asterisk has the system() application which will execute any arbitrary 
Linux command line so you can do pretty much anything.

Asterisk doesn't have the "native" ability to create log files as I think 
you described. How would you handle 2 calls entering the same context at 
effectively the same time? There are "race" conditions to consider both 
for file creation and writing.

Maybe this will give you some ideas:

[wildcard-test]
         exten = _!,1,                   verbose(1,[${CONTEXT}:${EXTEN}])
         exten = _!,n,                   system(logger -i -p local0.info -t ${CONTEXT} ${CALLERID(num)} entered context)
         exten = _!,n,                   answer()
         exten = _!,n,                   hangup()

         exten = _x,4,                   playback(demo-congrats)
         exten = _x,n,                   system(logger -i -p local0.info -t ${CONTEXT} ${CALLERID(num)} finished)
         exten = _x,n,                   hangup()

         exten = h,2,                    system(logger -i -p local0.info -t ${CONTEXT} ${CALLERID(num)} hung up)
         exten = h,n,                    hangup()

This will log every entry to the context to syslogd. You can configure 
syslogd (/etc/syslog.conf) to separate the log entries as desired.

This is pretty inefficient -- it creates at least 4 processes (2 on entry, 
2 on hangup) for every call.

I had an application several years ago that required logging how long each 
caller was in each context. I used resetcdr(w) and "enhanced" 
cdr_addon_mysql.c. When the call finished, I executed an AGI that added up 
the "cdrs" and rated the call.

If you post questions with meaningful subject lines, you may attract the 
interest of someone who has solved your exact problem and you make it 
easier for the next guy to research.
