The order of the codecs in the list, in the order specified by the
allow statements. I think the question stems from in the fact that
at the top of the Drupal the explanation is for the general section
of iax.conf. Further down the where the radio stanza is explained,
the order is explained.<br>

Since the 2 links referred to have GSM - on the Drupal link listed
as the first codec and the Github link lists GSM codec last in the
allow sequence. <br>
I need to ask when nodes begin negotiating is it done using the
order of the codec in the allow list? <br>

Interesting to learn some of the workings of iax.conf.<br>
<br>
I'm aware of the rest, however, I would encourage
iax.conf is modified to have the following priorities
for every connection stanza:<br>
ulaw<br>
g726aal2<br>
gsm<br>
<br>
this is to ensure audio quality is better than IRLP
and echo-stink. If you cannot tell the difference,
listen to a conversation on a local repeater, and the
same conversation with the convenient delay over IRLP
or echo-stink.<br>
<br>
You may then remember in days-past of analog cellular
listening to the person on the other end had more body
and fidelity.<br>
<br>
Regarding bandwidth, be it a DSL or mobile connection,
this should be a non-issue. Even 1G cellular data
connection will support two full-duplex uLaw streams.<br>
<br>
For hub nodes, 30 ulaw streams is right around
2.25Mbits. If this is a concern, perhaps the owner of
the hub should really consider putting the node
elsewhere. That's like trying to put a Pinto engine in
my E-350 and expecting it to work the same.<br>
<br>
Considering jitter and packet loss if it is thought a
higher bandwidth codec will cause this, such is not
the case. This is the cause of little or no
implementation of Qos/ToS in the WAN facing side of a
router. There are other external considerations, but
those are outside the scope of this thread.<br>
<br>
While on that subject a brief description of an
example is the node at my home. My connection,
fortunately, has maintained +25Mbps down and 5Mbps up,
I've have zero issues with jitter and packet loss with
QoS implemented, even while the kids are watching
netflix, skyping, and watching something on
youtube.... all at the same time.<br>
