[asterisk-users] chan_sip.c: Hanging up call

The string "5a2600300339934f704528bb14ed05e9 at MyAsterisk:5060" is the unique
identifier for the call in SIP known as the Call-ID.  If you have a packet
capture of the port 5060 SIP traffic, that identifier will be in each SIP
message related to the call, which also includes the full from and to

As an alternative to running a separate packet capture, you can enable SIP
message logging in Asterisk, which puts the full SIP message into the same
log file.  Be aware however that this can fill your hard drive quite
rapidly, as well as put additional load on the disk storage system.
