<pre wrap="">The term reliable / unreliable is wrong. If it is sent reliable,
the sender guarantees that the packet arrives. I would replace it
with:
All full frames must be immediate acknowledged upon receipt.
This acknowledgment can be explicit via an 'ACK' message (see
Section 8) or implicit based upon receipt of an appropriate
response to the full frame issued.
Note the RFC version of "must".

Duly noted, I'll change it per your suggestion. Thanks.

4.2 Mini frames
Mini Frames are so named because their header is a minimal 4 octets.
Mini frames carry no control or signaling data; their sole purpose is
to carry a media stream on an already-established IAX call. They are
sent unreliably. This decision was made because VOIP calls typically
can miss several frames without significant degradation in call...

Note the RFC version of "should not". That indicates that they *can*
be acknowledged if wanted, but it is not necessary. Is that the
expected behaviour? If not, it should be replaced with "must not
be".

<pre wrap=""><!---->I don't know that this has ever been considered. I lean toward saying
mini frames "must not" be acknowledged, in order to prohibit excessive
bandwidth usage. After all, if you're using mini frames you're passing
media and I can't think of any reason to acknowledge receipt of it
anyway.

mini frames have no sequence number, therefore there's no way to
acknowledge them. You couldn't acknowledge them if you really, really
wanted to.<br>
