It was used as a tool to test the core of FreeSWITCH in the early stages of development and we just kinda left it hanging around since it does at least work. We had to add a bunch of code to the stock iaxclient lib to make it threadsafe etc because the lib is designed to handle 1 or 2 calls and we are using it in a b2bua type env where hundreds of concurrent calls may be possible. That said, since we more or less forked the code to avoid generating support issues for the other soft-phones that use iaxclient, you may want to check if there were any bugs in the real version of the library that match your issue.<br> <br><span><a target="_blank"

We've had little to no demand for IAX2 so we have not focused very much on it. We do have strategies for creating a more robust and perhaps even an "improved" implementation of the IAX2 protocol. Alas, it's pretty much purely an academic exercise because there is little reason to implement it.<br><br><br><br><br><br><br><div> </div><div>Anthony Minessale II<br><br><span>FreeSWITCH <a target="_blank" href="http://www.freeswitch.org/">http://www.freeswitch.org/</a></span><br><span>ClueCon <a target="_blank" href="http://www.cluecon.com/">http://www.cluecon.com/</a></span><br><br>AIM: anthm<br>MSN:anthony_minessale@hotmail.com<br>GTALK/JABBER/PAYPAL:anthony.minessale@gmail.com<br>IRC: irc.freenode.net #freeswitch</div><div><br>FreeSWITCH Developer Conference<br>sip:888@conference.freeswitch.org<br>iax:guest@conference.freeswitch.org/888<br>googletalk:conf+888@conference.freeswitch.org<br>pstn:213-799-1400</div><div style="font-family:

Hi,<br><br>We're
running
FreeSWITCH
svn
Trunk
7697
on
SuSE
Linux
9.3
(x86-64).<br><br>I'm
experiencing
problems
with
DTMF:<br>The
IAX2
DTMF
frames
aren't
always
transferred
into
RTP
packets.<br>Sometimes
none
of
the
frames
are
translated,
sometimes
only
the
first <br>one
is
omitted.
All
the
IAX2
DTMF
packets
are
ack-ed.<br><br>Our
setup:<br><a target="_blank" href="http://PhoneFromHere.com">PhoneFromHere.com</a>
applet
(IAX2
protocol)<br>->
FreeSWITCH
(<a target="_blank" href="http://ns2.westhawk.co.uk">ns2.westhawk.co.uk</a>)<br>->
SIP
to
SystemX
(sofia/default/123@66.212.134.192)<br><br><br>I
searched
on
<a target="_blank" href="http://jira.freeswitch.org">jira.freeswitch.org</a>
for
a
bug
that
could
explain
this,
but <br>failed,
so
I
submitted
this
as
a
bug,
see<br><a href="http://jira.freeswitch.org/browse/FSCORE-109" target="_blank">http://jira.freeswitch.org/browse/FSCORE-109</a><br><br>Has
anyone
else
experienced
the
same
or
a
similar
problem?<br><br>Thanks,
