Outbound call testing

Outbound call testing began today. This is where a call is originated on the Asterisk/media gateway side toward the PSTN side. The number we dialed was terminated on the adjacent switch which sent and ANS immediately. This is within spec but ss7boost was expecting an ACM to preceed the ANS. We also found a need to implement the Circuit Reset Sending state machine (CRS) sooner rather than later.

We found a need for a special case of aborting a call waiting for span/chan assignment in the Woomerang component which is a minor fix.

In the course of testing we elected to manually reset the circuits in the connected trunk group which exposed us to the Circuit Group Reset procedure. Theis procedure runs indefinitely until 1) the CGR Reception state machine satisfies it, or 2) it is manually stopped on the switch. We'll have to build the CGRR state machine sooner rather than later too.
