You could use the system() application as suggested before.

You could also just start a console packet logger and just leave it 

 	sudo ngrep -O ngrep.pcap -W byline -d any <your-ani> port 5060

This will only capture packets containing your ANI which includes INVITE, 
Trying, OK, ACK, and BYE -- basically, the entire SIP dialog for the call.

This will only take about 4kB per call, so you can log over 250 calls per 
mega-byte so I'm guessing that should be possible.

Thanks in advance,
