Review request for Asterisk Developers.


Changes
-------

Freshen the diff.


Summary
-------

Added ability to send and receive ETSI Explicit Call Transfer (ECT) messages to \
eliminate tromboned calls.

Added ETSI support to an existing API call to send ECT messages when the upper level \
indicates to transfer specified calls.

The libpri API was extended to indicate to the upper layer that the far end requests \
the transfer of the indicated calls.

This is a two part review request.  Asterisk and libpri.  This is the libpri portion.
https://reviewboard.asterisk.org/r/520/ is the asterisk portion.

Note: This change is based off of the libpri/team/group/ccss branch because of needed \
infrastructure improvements done in that branch.

Testing
-------

A -- *1 -- *2  -- B&C

Party A is on an ISDN phone.

A calls B
A puts B on hold
A calls C
A hangs up to initiate transfer
The B and C parties are now connected to each other and the calls are only connected \
through *2.

A calls B
A puts B on hold
A calls C
A puts C on hold to retrieve B
A hangs up to initiate transfer
The B and C parties are now connected to each other and the calls are only connected \
through *2.

Repeat the above two tests but party A uses the EctExecute message instead of \
disconnecting to transfer the calls.

All four tests passed.


Thanks,

rmudgett
