Connected line is not updated when chan_dahdi/sig_pri or chan_misdn transfers a call.

Connected line is not updated when chan_dahdi/sig_pri or chan_misdn transfers a call.

When a call is transfered by ECT or implicitly by disconnect in sig_pri or
implicitly by disconnect in chan_misdn, the connected line information is
not exchanged.  The connected line interception macros also need to be
executed if defined.

The CALLER interception macro is executed for the held call.
The CALLEE interception macro is executed for the active/ringing call.
