[arm-allstar] Best Codecs for Portable Nodes

[Frank McKibben]

Re: etc/asterisk/iax.conf

I have previously reads ome information regarding codec usage in AllStar and
wish to confirm the editing of the iax.conf file.

I  wish to reduce the data usage on my portable node.  From previous
conversations with members of this group I understand that the ilbc codec is
much more efficient than the default  g726aa12 codec and using it has little
impact on voice quality while substantially cutting the data usage.   

Is implementing it is simply a matter of  rearranging the order that the
ilbc codec is listed in within the file?

For example:
under the [ general ] heading  I changed the order
From:
disallow=all

allow=g726aal2

allow=ilbc
allow=ulaw

allow=gsm                    
jitterbuffer=yes


TO: 
disallow=all

allow=ilbc
allow=g726aal2

allow=ulaw

allow=gsm                    
jitterbuffer=yes  

My confusion is that, these codecs appear several times in this file under
different headings and I am uncertain if I should be editing the order in
all references to them or just certain headings.  Could you comment on the
purpose of the different headings and what they control   General,
radio-proxy, radio etc.  

Thank you I really appreciate the knowledge you all share in this email
list.
