[Asterisk-Dev] Exception on 22, channel 5

Using Asterisk 1.0.9, with a TE405 card, and a 24 channel voice T1, I get 
this:

Exception on 22, channel 5

The call was from a Cisco 7960 (SIP) to a Zap channel (5).

What does 22 mean? What causes this?

Here it is in context:
Oct  5 11:27:54 DEBUG[3101]: Dialing '18779969646'
Oct  5 11:27:54 DEBUG[3101]: Deferring dialing...

Oct  5 11:27:58 DEBUG[3101]: Ooh, format changed from unknown to ulaw

and then, a few seconds later:

What part of Asterisk said DIALSTATUS=CANCEL. What does is really mean. 
Does it mean that the sip phone sent a CANCEL message to the switch?

Thanks,
