Greetings everyone,
I was wondering if there was a way to change the codec that Asterisk uses when 
streaming via MulticastRTP. Or perhaps a way to transcode the multicast stream.
In the CLI, when I have a multicast stream in progress, I am typing 'core show 
channel MulticastRTP/0x7f7........' to get lots of helpful information.
I have noticed that when I do a MULTICAST page and send data from MP3Player, I 
get no sound on my speakers and get the following from 'core show channel 
PJSIP/xxx':
NativeFormats: (slin)WriteFormat: slinReadFormat: slinWriteTranscode: No 
ReadTranscode: No 
I have noticed that when I do a UNICAST page and send data from MP3Player, 
everything works flawlessly and I get the following from 'core show channel 
MulticastRTP':
NativeFormats: (ulaw)WriteFormat: slinReadFormat: slinWriteTranscode: Yes 
(slin@8000)->(ulaw@8000)ReadTranscode: Yes (ulaw@8000)->(slin@8000)

The only thing that is changing is the following line in my extensions.conf 
file:
; For Multicast Pagingsame => n(next),Page(MulticastRTP/basic/239.1.1.2:6061,q)
; For Unicast Pagingsame => 
n(next),Page(PJSIP/107&PJSIP/108,ib(pjsip-auto-answer-header^addheader^1)|p})

Is there any way to get the MP3Player stream to transcode (as it does on the 
UNICAST stream) when I try to MULTICAST?
Thanks for the help,
--Matt
