[asterisk-users] Number of SIP messages per minute

[Eric "ManxPower" Wieling]

Just how many SIP packets do you think it takes to set up a call? 
Remember AUDIO IS NOT SIP!  SIP is for call control, setup, and teardown.

Do a "sip debug" in the CLI and see just how many packets it takes to 
setup a call.
