asterisk users - May 2009 - Request for feedback/testing on Multicast RTP Paging

Hello everyone,

A month ago I took on an issue on the Asterisk issue tracker
(https://issues.asterisk.org/view.php?id=11797) dealing with multicast RTP
paging.

This is the ability to send audio to phones (the phone must support it) and have
it played out the speakerphone. Using multicast RTP is great for
this because it does not incur the cost and weight of setting up a potentially
short call. Depending on the setup this can actually get to be quite
a big problem because when you involve phones subscribed to the state of another
they get told that the phone is in use. The amount of SIP traffic can
just spiral out of control.

Originally this issue was filed with a new application that performed the
paging. I took this application and turned it into a channel driver. This means
that instead of having a dedicated paging application for it you can just use
Dial(). This also means that in mixed environments you can use the Page()
application along with other phones that do not support the multicast RTP
paging.

So far I have gotten very little response on the issue so I am asking anyone on
this mailing list who is interested and has the time to test to please test
and provide some feedback.

A branch based off of trunk (as that is where the channel driver will go) is
available at http://svn.asterisk.org/svn/asterisk/team/file/issue11797

The dial string for the channel driver is in the form of
MulticastRTP/<type>/<destination>/<control address> where type
is either basic or linksys. The
control address is only needed for the linksys type.

Any feedback is welcome as a note on
https://issues.asterisk.org/view.php?id=11797 and will help to getting this into
the tree.

Thanks!
