<br>
Perusing through the iax.conf through a few allstar network linking distros, each seem to have their own preferred set of codecs.<br>
<br>
I'm rather disturbed that iLBC and speex remains in any of them, while I'm sure for compatibility of older installations. However, low quality bandwidth codes sounds no better than echo-stink. This is one of the reason why we use Allstarlink, for better audio quality, is it not?<br>
<br>
As I connect to different allstar nodes throughout the world, more-so in the US, some are using iLBC or gsm... and a majority are hub nodes. This to me, is unacceptable, and appears the codec being used are whatever the allstar box has been packaged with.<br>
<br>
So, given than I'm not a Steve Henke or Steve Zingman, but I want to ensure that I'm doing my part to achieve high fidelity through g711 codec and proper URI <-> radio hardware interfacing techniques.<br>
<br>
Which stanza in the iax.conf is for out-going connections?<br>
<br>
I was under the impression [radio-proxy] was, however, when a node with:<br>
disallow=all<br>
allow=ulaw<br>
allow=g726aal2<br>
allow=gsm<br>
<br>
connects to my node which has the *same* key=value pairs under [radio] stanza, I got the message something along the lines of:<br>
<br>
connected: IP<br>
codes available: g726aal2/gsm<br>
host codecs available: ulaw|g726aal2|gsm|ilbc<br>
actual codec: g726aal<br>
...<br>
<br>
bost sides do not have ilbc *anywhere*. The codec has been removed/deleted. Why does it still show up?<br>
<br>
What is the ultimate deciding factor of which codec is used if both side have codecpriority=mine?<br>
<br>
