IAXmodem released /iaxmodem/iaxmodem-1.3.4.tar.gz
-
Lee Howard committed [r56]
release 1.3.4
-
implement S11 and S12 jitter counters
-
Try to cope with upstream jitter.
-
This CONNECT message is superfluous.
-
Take 3. This correctly addresses the issue that was attempted to be fixed by r50 and r51.
-
The previous change doubled-up "NO CARRIER" messages in some instances. This approach should be safe from that.
-
Send NO CARRIER message if hangup occurs during data transmit
-
-
Continuation of yesterday's attempt to prevent multiple CONNECT messages following +FRH=3
-
bump
-
Prevent multiple CONNECT messages after +FRH=3 which could have been occurring when the DTE was slow enough that spandsp would buffer messages.

Thank you we appreciate your help.

Thank you. See: https://sourceforge.net/p/iaxmodem/code/46/

These changes are a contribution from Robert Boisvert and the Alpine Linux team to address issues that were encountered while running iaxmodem in valgrind.
-
In my testing it appeared that frame->session was released but I was not able to prove that conclusively and I didn't have the time to check where it was released. You can credit the Alpine Linux team for helping out.
-
Thank you. Who do I credit on this work? Regarding the libiax2/src/iax.c change, can you identify which structure was already freed and where it was freed?
-
I was able to resolve all the bugs with the attached patch file. Can you review and apply them if you agree? It contains the following adjustments. iaxmodem.c: initialize tioflags before using lib/libiax2/src/iax.c: remove a check on a structure that was already free'd lib/spandsp/src/at_interpreter.c: apply a patch that was provided in a later version of this library Thank you, Bob

Without being able to reproduce this crash and the associated valgrind log file, myself, it will be unlikely for me to be able to efficiently troubleshoot and determine either a code fix for iaxmodem or conclude that the fault lies within Alpine's new malloc() function. The valgrind log seems to point at five distinct issues: 1) conditional jump or move depending on uninitialized value in at_cmd_plus_VSID 2) ioctl call parameter pointing to uninitialized byte(s) in start_modem 3) ioctl call parameter...

We are using Hylafaxplus 7.0.3 to receive faxes from iaxmodem. The faxgetty program receives the fax, calls the faxrcvd script and then iaxmodem crashes. We put a pause in faxrcvd so that it would take no actions and iaxmodem still crashes. The malloc () function was recently updated on Alpine 3.13 so it is possible that it has a problem or that it is more sensitive to errors in the existing code. We would appreciate any suggestions you may have on how to track down this error.
-
What are the steps to reproduce this crash and the associated valgrind log file?
-
We are using iaxmodem 1.3.2 on Alpine Linux 3.13 and it is crashing when using Hylafaxplus 7.0.3. The problem seems to be triggered by an access to freed memory. I attached the valgrind log file which includes debugging data to identify the source of the problem. Can you assist us in finding in the root cause? Thank you, Bob
-
I don't know of anyone doing any active development to get data modes supported in iaxmodem. It's open source, so you're welcome to do add it, yourself, or hire someone to do it. No, I don't know of any other virtual modem to do data communication... it seems even less necessary than fax in an internet age.
-
Lanea Lucy Schwarz posted a comment on discussion Help
is there data mode planed to be supported then in future? or you know any other virtual modem software for this?
-
Did you see any suggestion anywhere that iaxmodem supported data modes? SpanDSP does have a lot of code to support data communication other than fax, but I've never seen them used. iaxmodem was designed for fax. You could have a custom application on the sender and the receiver to communicate data in the fax modes (such as using V.21) - but I don't think that you could get that with mgetty.
-
i just want text, no fax. later want attach mgetty to it EDIT: like in the old BBS days i want setup a BBS. want use mgetty to make modem to telnet gateway and then connect to telnet bbs

What happens if you call using a voice line into the modem and answer? Do you hear fax tones? (You should probably use AT+FCLASS=1, though. Do the session like I did it.)

Maybe something is wrong with the Debian build or the ptys there. I'm using Fedora and CentOS... but I don't recall hearing this kind of problem from anyone before. And iaxmodem has been around for a long, long time now.

the problem is that after ata i dont get any response, no ok, no connect and input isn't responding too. i try to simply test the connection for future use, but it don't work even here. no input is accepted, no text, nothing, it just hangs and do nothing

hi, installed iaxmodem 1.2.0~dfsg-3 and asterisk on fresh installed debian vm, set up 2 modems with default config from source code (iaxmodem-cfg.ttyIAX). connecting to both modems with minicom (minicom -D /dev/ttyIAX1). Can dial (ATDT 123) and answer on other modem (ATA) and then it hangs and dont accept any other input after this, no AT commands, no text. after killing connection it responds again. tryed similar setup on other system same result.

-
It's make's annoying habit of checking on the modification time of aclocal.m4, Makefile.in, and configure... coupled with weirdly old modification times in the spandsp-0.0.6 tarball. If you run this from your iaxmodem-1.3.1 directory: find . -exec touch -r configure {} \; ... then it should work. This will be resolved in the next release.

iaxmodem has a built-in version of spandsp which has those debug messages commented-out. However, iaxmodem can be built using a shared system spandsp DSO, and if your installation is using that, then I'd guess the debug messages are there. They can be disabled in spandsp unsetting SPAN_LOG_FLOW in the various spandsp logging levels, but I don't immediately know how that's done. My advice would be to uninstall iaxmodem and reinstall it from source - this time building it with static libraries rather...

I am having the same problem! Asterisk 13.4 and iaxmodem 1.3.0. I traced it to a test in chan_iax2.c. It was complaining that the "peer was not dynamic". I commented out that test, and now it registers successfully. / if (!ast_test_flag64(p, IAX_DYNAMIC)) { if (authdebug) ast_log(LOG_NOTICE, "Peer '%s' is not dynamic (from %s)\ goto return_unref; }/ My understanding is that "dynamic" means that a peer does not have a configured IP address - so it is wherever it is. Iaxmodem is of course not "dynamic"...

Your iax.conf context entry looks a bit odd with "dynamic=yes". (Is that even an allowable directive?) The "host=" and "port=" entries seem to conflict with any meaning of "dynamic" or registration. Anyway, probably the best approach to troubleshooting registration errors is to watch the Asterisk CLI as it attempts registration and to see what it says.

There is some V.34 support in SpanDSP. I don't think that it's patent-encumbered any longer. However, the last time that I tested V.34 in SpanDSP I couldn't get it working well against other V.34 (SuperG3) fax modems. (Maybe I didn't test correctly?) So, I didn't bother getting into the necessary developments for the required T.31 interfaces. (Once the V.34 modems are working reliably in SpanDSP then IAXmodem will still need the associated T.31 interfaces developed - also in SpanDSP.)

Hi, I'd like to know if IAXmodem already supports fax speed transmission at 33.6kbps. I've found from this page (https://www.voip-info.org/asterisk-iaxmodem/) that: "Iaxmodem uses the spandsp library. So currently its modulation protocol support covers V.27ter, V.29 and V.17. V.34 (Super G3) support is not available, and won’t become available in the near future for patent reasons..." Which means that fax speeds from 2400 bps to 14400 bps are supported. However, I dont know how long has been since...

Sorry but late response, I can't be sure, but seems randomly. In non-daemon mode seems happened less. Finally I work with static config without register and all works fine. I go to try to get some packet captures on daemon and non-deamon mode to see if this is a asterisk side problem or iaxmodem side. Thanks

Did the -lm need to be moved all the way to the end? Or did it just need to be moved to after the $LLIBS ?

How are you starting iaxmodem? Does this happen if you start iaxmodems with non-daemon mode? Does the problem happen only with some of the iaxmodems? Or does it happen to all of them even randomly?

This morning, I also took my test server I built (on centos 7), on wich I had setup an iaxmodem and hylafax from scratch, and built asterisk (13.17.1) from source, setup an iax trunk between my production server and this server, so that I can get incoming calls from PSTN and to my surprise, I got the same outcome !

So I got arround and did a reboot, and of course, didn't change anything. I still got calls rejected by iaxmodem. Any more ideas ?

11.17.1 It has been installed like 2 years ago, the yum channel hasn't had any updates since more than a year, so that version the same since the last time it worked... I will try to plan a maintenance and reboot the server, that's the last thing I can try at the moment.

What version of Asterisk are you using? I have used many versions of Asterisk up to these versions which I currently run: 1.8.20.1, 11.8.1, and 11.20.0.

Trafic to/from localhosty should be allowed by the built-in iptables. I disabled to test, same thing. Selinux is disabled. I don't see anything that can get in the middle of asterisk and iaxmodem.

So, unless there is some kind of bug involved (and this is the first report I've seen of this) there is something else that's interfering. So, maybe a firewall or something like SElinux or something. Have you investigated those?
-
That's pretty much it, that's where I beleive the problem is.

So, bottom line is that you're seeing this in your Asterisk CLI...

What does your dialplan look like where it sends calls to iaxmodem?

I don't know how, but now I can't reproduce the case where I had ringing on iaxmodem. I'm bakc to square one when iaxmodem responds systematicly busy. Even when hylafax and faxgetty stoped.

No, the call doesn't appear to reach faxgetty. It looks like it's iaxmodem that respond it's busy.

But when faxgetty is running you do get an answer? But no session log? Do you see the rings appear in the FaxGetty logs from syslog?
