[Iaxclient-devel] ring sound problem if i choose another device for ring!

[Atuc <at...@gm...>]

hallo,

i experienced a problem in the latest iaxlib with the ring ton, if i select 
another audio device (soundcard) for the incoming ring as the headset 
device, i get a distort sound if i get an incomming call. if i connect the 
call, the sound continues until the connection stays.

i have just testet with the latest iaxcomm (0.99pre6) on windows and its 
the same, i have similar experience under linux.

anybody else has the same problem?
any idea what it is?

This can be solved by using config.h in libiax2, or moving the 
definition of ostype from config.h to the flags.

lib/Makefile.am is already prepared for that. You only have to change
"if FALSE" to "if TRUE" at the end of the file.

The following files aren't included in the libiax2 dist but in
lib/libiax2/src

You have to enable all clients in configure before make dist. Maybe you
also should enable maintainer mode, which will add some rules and
dependencies that rebuilds configure if configure.ac changes for example.

     ./configure --enable-clients=all --enable-maintainer-mode

I don't know why that happens. It works for me with the mingw32 cross
compiler on Debian and cygwin and msys+mingw on Windows.

configure probably has detected that wx/xrc/xmlres.h isn't present, but
iaxcomm is activated anyway since you have overridden the automatic
detection of supported clients.

I don't think iaxphone should be removed. It's useful on systems
without wxrc and the xrc library, which aren't installed by default.

It compiles at least with the mingw32 cross compiler in Debian. I
haven't tried it on Windows yet, since I got rejects when patching the
iaxclient tarball.

Just change "bin_PROGRAMS=testcall" to "noinst_PROGRAMS=testcall" in
simpleclient/testcall/Makefile.am

It needs a way to specify which portaudio device to use.

Hi,

it's possible to build a shared library with my autoconf patch. I have 
recently tested it on mingw (+msys) on Windows, and it worked.

If you are interested, but don't have autoconf and automake and therefor 
can't run autogen.sh, I can send you a patch with the auto generated files.

IAX2 sends a calling name and a calling number.  I think there have been
some changes in exactly what is included in each field (I think calling name
at one time was "name <number>")

I'll tweak iaxComm so it displays both.

[Iaxclient-devel] iaxcomm and caller-ID

[Marc S. <iax...@al...>]

Hi,

I have configured Asterisk with SIP phones, IAX2 interasterisk and with
a ISDN HFC-S and a ISDN phone. In all cases I get caller-ID transferred
correctly.

However, with all the versions of iaxcomm I tried (including 0.99pre6) I
don't see the caller-id information.

Is that a known bug, or is there something specific I should pay
attention when setting up iax.conf in Asterisk ?

I assume the bug is not within Asterisk since caller-ID is correctly
sent to other IAX2 connections.

Thank you for any help on the subject!

Works for me, on a Dell 600m, RedHat 9, 2.4.25 kernel, alsa, talking
to an echo test extension on an asterisk.

BTW, I had to remove the old .rc file from my home dir before it
would start up.  I also made this change so that preferred codec
is initialised:

[Iaxclient-devel] Clicks instead of cound sent by tkiaxphone

[Mikhail R. <mr...@ra...>]

Hello,

Thank to all your help, I was able to test tkiaxphone - with disastrous 
results :(

Sound is received OK. But sending is hopelessly distorted. The echo test 
returns click-click-click every time I speak into the microphone - no trace 
of the voice. 

(But clicking is only heard when I do speak.)

This may be connected with the fact that my sound subsystem is an ac97 codec 
in i865PE, driven by alsa, with OSS emulation enabled of course. ("rec" 
records OK at 8 khz.) According to a friend, he sees the same problems with 
iax2 cliens on similar sound hardware even on Windows.

Sounds like you're trying to compile against libiax, and not libiax2. 
libiax is no longer supported (I should probably just remove it from CVS 
one of these days).

Setting this to a value > 0 will use a DSP-based VAD algorighm from

Hello,

I am helping somebody test a new asterisk installation, using tkiaxphone. It 
does not work right - I hear only rhythmic noise on a loopback call (the 
noise only comes when I speak into the microphone). On a call that transmits 
a beep from his side, things work all right.

I need to make sure that the server is at fault, so I need to test the client 
with a working server. Could anyone who has such a server let me have an 
account with ANYTHING that works both ways, not just transmitting to me? It 
can be a loopback call, or a live talk attempt. I could tell you the latest

I've implemented the changes described above, and committed this to CVS. 
It is now enabled by default.

Can people please give this a try. I'm especially interested in hearing 
if it improves the situation for people having the problem Steve 
describes: Audio _from_ iaxclient, heard from another VoIP client was 
choppy/broken up.

Doh! 

Sorry about that.  I've committed those now.

I've also changed the align stuff a bit, but it should work the same, 
based on simpler functions that are going into asterisk..
