How to enable D-Channel Pcap recordings

 When troubleshooting PRI/BRI connections is it sometimes useful to have a packet capture from the DChannel. The pcap will show you what is happening on the link at a low level during a call. These steps will enable pcap recording on the DChannel.

4. After making your test calls, the pcaps from those calls will be saved in the log (default: /logs/dchan-pcap-recording/)
