[Iaxclient-devel] Problems compiling iaxclient with MSVC6

[Joaquin C. A. <e98...@fr...>]

Hi!

I've tried to compile iaxclient (HEAD) on windows with MSVC6 but
unsuccessfully until now.

My first problem come from the current project, as it tries to build a
version with libiax 1, and this version doesn't compiles.

So I've changed the libiax files for the libiax2 ones, but I'm still
experiencing some problems.

In the libiax2\src\iax.c file, line 670, I'm getting a:

error C2229: struct '__unnamed' has an illegal zero-sized array

It seems to complain due to the last member of iax_frame. Does anybody knows
what should I do to make it work?

Thank you for any comments!

Cheers,

[Iaxclient-devel] No ring/out of order packets -- part 2

[Steven S. <ss...@so...>]

Folks,

I have a user who has alerted me to the fact that on occasion IAX Phone
ignores incoming calls.  I have turned on the tracing and it appears that we
have situations where messages arrive out-of-order again.

The last time we ran into this, it was a result of confusion over how to
handle the registration.  We were leaving it open, and that seemed to cause
the phone to stop responding eventually.

Well, this seems eerily similar.  I have also noticed the Qualify option
does not appear to work with iaxClient-based clients, but does with others
(Asterisk and FireFly).  If you try to qualify an iaxClient-based device, it
fails to ring at all - it shows as unavailable or something when you do
'iax2 show peers'

Are any of these conditions related?  Anybody (Adam?) have any thoughts on
this?  I'll code it if you can come up with the answer.

Here's the trace:

libiax2/src/iax.c line 2020: Received iseqno 0 not within window 5->5
libiax2/src/iax.c line 2039: Packet arrived out of order (expecting 2, got

It should work with esddsp, at least it did some time ago when I tried it..

If it doesn't, it would be possible to write an esd driver for either 
iaxclient itself, or (probably a better idea) for portaudio.

[Iaxclient-devel] esd compatible?

[Ronan S. <ron...@wa...>]

Hi,

It is possible to get iaxcomm (and I guess the iaxclient library) to 
work with esd(esound) ? The idea is to be able to have an audio 
application and iaxcomm that can work at the same time. At the moment, 
if I have xmmx running, I won't be able to hear any incoming calls.
I tried to run iaxcomm with esddsp, but iaxcomm doesn't work.

An other way arround would probably be to create two pipes (in and out) 
and I could use esdrec/esdcat to read/send the sound to the esd deamon 
but I can't change the audio settings within the GUI.

I'm using the latest CVS and linux 2.4.26, esound 0.2.34.

Thanks, Ronan.

I have the following setup:
asterisk1 -- iax2 ilbc (1)-- asterisk2 -- iax2 gsm (2)-- iaxclient

On the leg #2 packets goes from asterisk to iaxclient  with 20,40,20,40ms... 
timestamps. Packets sizes are 33,66,33,66...etc.

Re: [Iaxclient-devel] iaxclient_lib small fix

[Steve K. <st...@st...>]

Thanks Dmitry.

It was also wrong in the IAX1 case, although I don't even know if the 
IAX1 stuff even compiles anymore.

Just out of curiosity, what are you doing that actually causes this case 
to happen?  It would only happen, if you were using frames > 20ms long.

I'm actually thinking of making an option for iaxclient to use larger 
frames, because it uses much less bandwidth, but the tradeoff is 
slightly longer latency, and also more perceptible glitches when there's 
a frame dropped, etc.

[Iaxclient-devel] iaxclient_lib small fix

[Dmitry M. <ar...@od...>]

Hello,

In iaxclient_lib.c in handle_audio_event sub there is a code:

#ifdef IAXC_IAX2
        while(total_consumed < e->datalen) {
                cur = decode_audio(call, fr,
                    e->data,e->datalen-total_consumed,
                    iEncodeType);
#else

It should be replaced with:

#ifdef IAXC_IAX2
        while(total_consumed < e->datalen) {
                cur = decode_audio(call, fr,
                    e->data+total_consumed,e->datalen-total_consumed,
                    iEncodeType);
#else

It gives more clear audio when "while" construction actually working.

[Iaxclient-devel] Using wiax.dll with MFC

[<ale...@ya...>]

Hello to everyone on the list,
 
can someone please help me to figure out what I'm doing wrong?  I have built wiax.dll correctly (thanks Dan).  Then I use it this way:

typedef int (*IAX_Initialize)(int audType, int nCalls);

IAX_Initialize IAXInitialize;


HINSTANCE hinstLib = LoadLibrary("wiax");

if (hinstLib == NULL) {

AfxMessageBox("wiax.dll not found", MB_OK, 0);

return;

}

IAXInitialize = (IAX_Initialize) GetProcAddress(hinstLib, "IAX_Initialize");

if (IAXInitialize == NULL)

AfxMessageBox("IAXInitialize == NULL", MB_OK, 0);

else

(IAXInitialize)(AUDIO_INTERNAL_PA, 1);

 

This last call to IAXInitialize causes a memory violation and the app ends.  I modified the DLL not to call  iax_initialize but to print a message with MessageBox and it works fine.  Also are there any suggestions about where in the MFC code I should start the IAX initializations.  It is just a CDialog.

 

Thanks in advance for any help

[Iaxclient-devel] RE: [Asterisk-Dev] Basic Conferencing from IAX2, other VoIP Channels

[Steven S. <ss...@so...>]

Here's my take on the process:

Personal Conferencing for IAX2

For every IAX2 user that has the feature conf enabled (a new entry in the
iax.conf and/or the database) chan_iax2 will support the ability to
conference two or more parties using the MeetMe application, or a derivation
of the MeetMe app.
	
A new IAX2 command for Conference (CONF) will be created.  The command will
require one or more IEs that indicates whom to conference.

[Creating The Initial Conference]
---------------------------------
The client (UA) should recognize that a press of the CONF button with a
single active call to mean "put this call on hold while I establish another
call for a conference".  The client will then place the active call on hold
and select a different appearance which can be used to establish the seconds
call.  The client will likewise recognize the second click of the CONF
button to mean "Ok, conference these calls together" and will send a CONF
command to Asterisk.  Asterisk will move the held party into the conference
room, then move the two parties to the active call into the meeting room.
The appearance used to conference the additional party will be freed and
return to idle (i.e. the call will be destroyed).

[Adding Parties To An Existing Conference]
------------------------------------------
If the user chooses to add an additional party to the conference by again
pressing the CONF key, he/she will put the conference on hold and access
another appearance for dialing.  When the call to the new party is active,
the user can again press CONF to add the new active party.  Somewhere along
the line, the system will need to recognize that the user's personal
conference room _is_ the held party and will simply move the new remote
party into the conference.  The client should be smart enough to re-select
the held conference channel (taking it off hold) so that all parties are
again active.

[Simulating This Scenario]
--------------------------
I managed to simulate this by using static conferences with extension
numbers and the Manager API.  I am able to merge the calls into the static
conference without any real issue.  I simply redirect the held channel to
the extension for the MeetMe, then redirect the two active channels to the
same extension.  All parties wind up in the bridge.  Works fine.

[Rules/Thoughts]
----------------
The conference application should be silent and pin-less by default.

The conference should collapse when the conference count reaches 1 instead
of zero.

The conference should collapse when the "host" (i.e. the IAX user) drops out
of the bridge.

Some similar mechanism for dropping (kicking) conference members should be
included in the package.

[Programming The Conference Mechanism]
--------------------------------------
The question is, what is the best way to programmatically affect this same
set of circumstances?  I want to make it work from IAX2 semi-automagically.
Adding the command to IAX2 looks pretty easy.  Where I get lost is in the
moving process.

I don't want to have to create an extension for each user's conference
number.  I want to activate the app_meetme code, passing in the user's ID.
(i.e. [iaxuser@192.168.1.194:5469]) as the name of the conference to either
create or join.  I believe this requires some small changes to MeetMe to
support the named dynamic conference.  But where I really get lost is in the
process of redirecting the channels to the MeetMe app in the first place.
Is there any code similar to pbx_async_goto_by_name that takes an
application as a destination, rather than an extension/priority?

Anybody want to kick me in the right direction here?

Thanks,

Steve

Re: [Iaxclient-devel] Basic Conferencing from IAX2, other VoIP Channels

[Steve K. <st...@st...>]

I don't know how you'd implement exactly what you want to do, but while 
most office phones have "conf" buttons, the conferencing is most 
definitely done in the PBX, and not in the phones themselves.

[Iaxclient-devel] Basic Conferencing from IAX2, other VoIP Channels

[Steven S. <ss...@so...>]

Asterisk's MeetMe is powerful and flexible, but sometimes you just want to
do an old-fashioned basic conference from the client, without having to
transfer everybody into a conference room.  This is pretty common
functionality on most office phone systems.

Scenario:

1.  You (party A) are on an active call with party B.
2.  You decide to add in another party (C).
3.  You key the CONF button on your business set.
	- Party B gets MOH or silence.
	- Party B's appearance on your phone goes to the HELD state.
	- You get new dial-tone on a new appearance
4.  You dial the number for party C.
5.  Party C answers and you communicate briefly.
6.  You press the CONF key again to establish the conference
	- The bridging takes place in the PBX/KSU
	- Party B is pulled out of MOH-land and added to the new call
	- Party B's appearance returns to the ACTIVE state

Now you are conferenced.  Both call appearances show active.  You can even
follow the same set of steps to conference in another user if you have
additional appearances on your set.

In Asterisk using most VoIP phones (soft or hard) this scenario does not
play out.  You wind up transferring party A into the MeetMe, calling party B
and transferring them into the MeetMe, then dialing into the MeetMe
yourself.

This is further complicated by the fact that any given static MeetMe may or
may not already be occupied by others doing the same thing.  Dynamic MeetMes
make this a bit more flexible, but there's little documentation to the
dynamic feature.

Is there an elegant way to execute dynamic conferencing in Asterisk?  Can
this be done without building conferencing logic into the client UA?  If so,
how?

If not (which I think is the case), how do we add this in?  I have a number
of clients using my IAX Phone who are not really happy about having to jump
through hoops to handle spontaneous conferences.

I would be happy to _try_ to code the solution into IAX2 (both chan_iax2 and
libiax2) if somebody can tell me where to begin.  I would think there has to
be some way to add in an IAX2 command to merge two calls or to command
Asterisk to bridge the calls at the server.

Also, is there a way execute such a conference from SIP, MGCP, H323, or
other protocols?  If so, who wants to implement it?

Any thoughts would be appreciated.  Apologies in advance if I missed some
really simple way of doing this.

Thanks,

Steve

[Iaxclient-devel] Transfer Park and other cmds for Asterisk

[The S. <kc...@al...>]

Hai All,

Does anybody know exactly how the cmds for * should work, i've been trying to 
get the following done but it would not work, is there a special key to 
touch, or something else special ??

I used different clients also, my own (build on libiax1 & 2) but got stuck 
when I want to communicate with the pbx. I setup a line between A and B, 
where I use iaxtransfers=no in the iax.conf, then when I try for example to 
park the call by dialing 700 or #700, I can see the the digits come from 
client A to the * and he forwards them to client B, instead of acting on them 
..

in the extensions.cnonf I used the rules like this 

[default]
include => parkedcalls
exten => 100,2,Dial,IAX/100/s|30|t
exten => 200,2,Dial,IAX/200/s|30|t

also the transfer shows the same effect .. the only thing that works is a 
blind transfer ..

Should I use an special func to tell * the cmd's ??? I thought it was all 
handled by the iax2 (ies).


Anybody any idea ?

[Iaxclient-devel] FASD project: Online survey launched

[<ben...@id...>]

Dear Open Source developer

I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate.
You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it.

With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development.


With many thanks for your participation,
Benno Luthiger


PS:
The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/.

[Chris G. N. <cg...@gl...>]

so, after a first pass on the sources, perhaps add a new interface/beef =

int iax_init(int preferredportno, int ipflavor)  {

    netfd =3D socket(AF_INET, ip_flavor, IPPROTO_IP);

}


and the existing routine would become a wrapper...

Bummer :-(

So back to the original thought here, I would just assume have the TCP =
proxy code just 'baked' into an IAX client as an optional connect =
method, since the process of installing/configuring anything additional, =
particularly if it involved Java, will lose > 95% of potential users, =
and defeats the purpose of a ~100Kbyte download.

Need to dive into the sources...

If this is already done, packaged, and reasonably priced, and can still =

Can you provide more info on this setup?

Actually, we do IAX over either straight TCP, or actual rfc-compliant=20
HTTP.=20

Unfortunately, we do this with a proprietary program [external to=20
iaxclient], and can't release it, but I think there are similar=20
solutions available.  They don't need to be built into iaxclient to use=20
them.  The same reasons that make IAX work well with NATs make it work=20
fine with tunnels as well.


So basically, what you need to do is this:

          Client machine                    =20
Network                            Server
[Iaxclient <-UDP-> tunnel ]  [<- HTTP or TCP -> ] [ tunnel<-UDP-> =
asterisk ]

The tunnel programs at either side are what you need, and it needs to=20
support UDP tunneling.

Are there somebody planning to add recording features to IaxClient ?
I would like to have this functionality as soon as possible.=20

I could allocate a C Programmer to do that, if somebody show me the Road=20

I think Steve Sokol started working on this, but I don't believe he has 
finished; not sure how far he got.

I've been working on both iaxclient and app_conference, and have 
committed a bunch of changes to make things more reliable.
