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>
