Summary
-------

Add the ability to announce a call to an endpoint when there are no B channels available.
A call waiting call is a SETUP message with no B channel selected.

Relevant specification: EN 300 056, EN 300 057, EN 300 058

This is based off of the team/rmudgett/aoc_event branch to get the accumulated features so far.

Testing
-------

Party A ---> * ---> * ---> Party B

The link under test is between the two asterisk boxes.

1) Normal calls still work.
A calls B (Link under test is not congested.)
B answers
Call connects

2) Link congested and no B channel is released to take the call.
A calls B (Link under test is congested.  SETUP indicates no B channel.)
B answers
Call is immediately disconnected when B answers because there are no B channels.

3) Link congested and a B channel is released to take the call.
A calls B (Link under test is congested.  SETUP indicates no B channel.)
B channel is released on the link under test.
B answers
Call connects
