[asterisk-users] libpri version 1.4.5 Released

[Asterisk Development Team]

The Asterisk development team has released version 1.4.5 of libpri. This
release was made solely to correct a problem introduced in version 1.4.4.

In February of 2008, a change was made in libpri to support inband audio
(progress) when the far end of a PRI circuit issues a RELEASE message,
indicating they want to terminate the call. This change was necessary
for some applications where the telco providing the circuit wants to
provide a 'release message' before actually hanging up the call.
Unfortunately, many users have PRI circuits that are not compatible with
this behavior, and this results in their PRI B-channels being left open
for anywhere from 2 to 20 seconds (or more) before the calls are finally
terminated.

This version of libpri retains the ability to operate in this mode, but
it is now a configurable option which defaults to being 'off'. The next
releases of Asterisk will have configuration options to turn this
behavior on if the user desires.

Thanks for using libpri and Asterisk!
