asterisk announce - Dec 2011 - Asterisk 1.8.8.0 Now Available

The Asterisk Development Team is pleased to announce the release of
Asterisk 1.8.8.0. This release is available for immediate download at
http://downloads.asterisk.org/pub/telephony/asterisk/

The release of Asterisk 1.8.8.0 resolves several issues reported by the
community and would have not been possible without your participation.
Thank you!

The following is a sample of the issues resolved in this release:

* Updated SIP 484 handling; added Incomplete control frame
   When a SIP phone uses the dial application and receives a 484 Address
   Incomplete response, if overlapped dialing is enabled for SIP, then 
the 484
   Address Incomplete is forwarded back to the SIP phone and the HANGUPCAUSE
   channel variable is set to 28. Previously, the Incomplete application
   dialplan logic was automatically triggered; now, explicit dialplan 
usage of
   the application is required.

* Prevent IAX2 from getting IPv6 addresses via DNS IAX2 does not support 
IPv6
   and getting such addresses from DNS can cause error messages on the 
remote
   end involving bad IPv4 address casts in the presence of IPv6/IPv4 
tunnels.

* Don't crash on INFO automon request with no channel
