Subject: asterisk: segfault with IAX2-IAX2-DAHDI and use of jitterbuffer Package: asterisk Version: 1:1.6.2.9-2 Severity: important Tags: upstream
*** Please type your report below this line *** A softphone (Zoiper Linux) connects to this asterisk box via IAX2 The call is forwarded via Dial() to another asterisk box via IAX2 A jitterbuffer with the following setup is used on the inbound (softphone) channel jitterbuffer=yes forcejitterbuffer=yes maxjitterbuffer=1500 maxjitterinterps=10 resyncthreshold=1000 jittertargetextra=1500 The remote asterisk box does further route the call via DAHDI to the POTS (seems not relevant, bug happens also when echoTest() is used remote) With this setup Asterisk will produce a repeatable crash after 1-2s of audio, sometimes 3-6s, probably depending on actual jitter at the time. Changing "forcejitterbuffer" to "no" will eliminate the problem, but also no jitterbuffering will take place. The inbound connection is via high latency, high jitter, low bandwith connection (latency between 700ms and 1100ms). Jitterbuffer in this case makes the difference between usable although lagged audio and unusable audio. This is my first bugreport, hope it is helpful. I have worked around this problem at the moment by switching to IAX2-SIP-DAHDI routing which works but is undesirable for other reasons. -- System Information: Debian Release: squeeze/sid APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i586) Kernel: Linux 2.6.36 Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages asterisk depends on: ii adduser 3.112 add and remove users and groups ii asterisk-config 1:1.6.2.9-2 Configuration files for Asterisk ii asterisk-sounds-main [ 1:1.6.2.9-2 Core Sound files for Asterisk (Eng ii dahdi 1:2.2.1.1-1 utilities for using the DAHDI kern ii libasound2 1.0.23-2 shared library for ALSA applicatio ii libc-client2007e 8:2007e~dfsg-3.1 c-client library for mail protocol ii libc6 2.11.2-6+squeeze1 Embedded GNU C Library: Shared lib ii libcap2 1:2.19-3 support for getting/setting POSIX. ii libcurl3 7.21.0-1 Multi-protocol file transfer libra ii libgcc1 1:4.4.5-4 GCC support library ii libglib2.0-0 2.24.2-1 The GLib library of C routines ii libgmime-2.0-2a 2.2.25-2 MIME library ii libgsm1 1.0.13-3 Shared libraries for GSM speech co ii libiksemel3 1.2-4 C library for the Jabber IM platfo ii libjack-jackd2-0 [libj 1.9.5~dfsg-19 JACK Audio Connection Kit (librari ii libldap-2.4-2 2.4.23-6 OpenLDAP libraries ii liblua5.1-0 5.1.4-5 Simple, extensible, embeddable pro ii libncurses5 5.7+20100313-4 shared libraries for terminal hand ii libnewt0.52 0.52.11-1 Not Erik's Windowing Toolkit - tex ii libogg0 1.2.0~dfsg-1 Ogg bitstream library ii libopenais3 1.1.2-2 Standards-based cluster framework ii libopenr2-3 1.3.0-2 MFC/R2 (telephony) call setup libr ii libpopt0 1.16-1 lib for parsing cmdline parameters ii libpq5 8.4.5-0squeeze1 PostgreSQL C client library ii libpri1.4 1.4.11.3-1 Primary Rate ISDN specification li ii libradiusclient-ng2 0.5.6-1 Enhanced RADIUS client library ii libresample1 0.1.3-3 real-time audio resampling library ii libsdl1.2debian 1.2.14-6.1 Simple DirectMedia Layer ii libcurl3 7.21.0-1 Multi-protocol file transfer libra ii libgcc1 1:4.4.5-4 GCC support library ii libglib2.0-0 2.24.2-1 The GLib library of C routines ii libgmime-2.0-2a 2.2.25-2 MIME library ii libgsm1 1.0.13-3 Shared libraries for GSM speech co ii libiksemel3 1.2-4 C library for the Jabber IM platfo ii libjack-jackd2-0 [libj 1.9.5~dfsg-19 JACK Audio Connection Kit (librari ii libldap-2.4-2 2.4.23-6 OpenLDAP libraries ii liblua5.1-0 5.1.4-5 Simple, extensible, embeddable pro ii libncurses5 5.7+20100313-4 shared libraries for terminal hand ii libnewt0.52 0.52.11-1 Not Erik's Windowing Toolkit - tex ii libogg0 1.2.0~dfsg-1 Ogg bitstream library ii libopenais3 1.1.2-2 Standards-based cluster framework ii libopenr2-3 1.3.0-2 MFC/R2 (telephony) call setup libr ii libpopt0 1.16-1 lib for parsing cmdline parameters ii libpq5 8.4.5-0squeeze1 PostgreSQL C client library ii libpri1.4 1.4.11.3-1 Primary Rate ISDN specification li ii libradiusclient-ng2 0.5.6-1 Enhanced RADIUS client library ii libresample1 0.1.3-3 real-time audio resampling library ii libsdl1.2debian 1.2.14-6.1 Simple DirectMedia Layer ii libsnmp15 5.4.3~dfsg-1 SNMP (Simple Network Management Pr ii libspandsp2 0.0.6~pre12-1 Telephony signal processing librar ii libspeex1 1.2~rc1-1 The Speex codec runtime library ii libspeexdsp1 1.2~rc1-1 The Speex extended runtime library ii libsqlite0 2.8.17-6 SQLite shared library ii libss7-1 1.0.2-1 Signalling System 7 (ss7) library ii libssl0.9.8 0.9.8o-2 SSL shared libraries ii libstdc++6 4.4.5-4 The GNU Standard C++ Library v3 ii libsybdb5 0.82-7 libraries for connecting to MS SQL ii libtiff4 3.9.4-5 Tag Image File Format (TIFF) libra ii libtonezone2.0 1:2.2.1.1-1 tonezone library (runtime) ii libvorbis0a 1.3.1-1 The Vorbis General Audio Compressi ii libvorbisenc2 1.3.1-1 The Vorbis General Audio Compressi ii libvpb0 4.2.49-1 Voicetronix telephony hardware use ii libx11-6 2:1.3.3-3 X11 client-side library ii libxml2 2.7.7.dfsg-4 GNOME XML library ii unixodbc 2.2.14p2-1 ODBC tools libraries ii zlib1g 1:1.2.3.4.dfsg-3 compression library - runtime Versions of packages asterisk recommends: ii sox 14.3.1-1 Swiss army knife of sound processi Versions of packages asterisk suggests: ii asterisk-dev 1:1.6.2.9-2 Development files for Asterisk ii asterisk-doc 1:1.6.2.9-2 Source code documentation for Aste ii asterisk-h323 1:1.6.2.9-2 H.323 protocol support for Asteris -- Configuration Files: /etc/init.d/asterisk changed [not included] -- no debconf information -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
