Дано: asterisk 1.0.9
ОС: Linux Gentoo 2005.0
Ядро: 2.6.11-gentoo-r3

Никак не могу разобраться со следующей багой, подозреваю что дело в звуковой карте.
Пытаюсь записать голос с телефонной трубки:

=== cut ===
*CLI> -- Executing Answer("OH323/R17736", "") in new stack
-- Executing VoiceMail("OH323/R17736", "297101") in new stack

Press any key to continue...
=== cut ===

Звукашка определяется след. образом:

intel8x0_measure_ac97_clock: measured 50046 usecs
intel8x0: clocking to 48000
ALSA device list:
#0: Intel ICH5 with ALC658 at 0xfc001000, irq 17

Sound card тут не причем, на машинах с zaptel ее надо выключать в биосе и не грузить модули chan_oss.so и chan_alsa.so.
А gentoo kernel небось пропатченный всякими security темами? Погляди системный лог, думаю это ядро прибивает asterisk.

Какое ядро посоветуете?

я последнее время собираю 2.6 чистое, граблей пока не было.

Поставил ядро 2.4
#uname -a
Linux asterisk 2.4.28-gentoo-r8

Теперь при записи вываливается с криками:

=== cut ===
-- Executing Answer("OH323/R4767", "") in new stack
-- Executing VoiceMail("OH323/R4767", "297101") in new stack

-- x=0, open writing: /var/spool/asterisk/voicemail/other/297101/INBOX/msg0012 format: gsm, 0x8180598
Segmentation fault
=== cut ===

Иногда говорит вот это:

=== cut ===
-- x=0, open writing: /var/spool/asterisk/voicemail/other/297101/INBOX/msg0013 format: gsm, 0x8166fa0
Ouch ... error while writing audio data: : Broken pipe
Segmentation fault
=== cut ===

В "/var/log/asterisk/messages" ничего по этому поводу не пишется :(

Где грабли? :-(

попробуйте включить дебаг в астериске и посмотреть что пишется в него перед segmentation fault.
И еще - Linux asterisk 2.4.28-gentoo-r8 - это не "чистое" ядро , а тоже с дополнительными патчами. Хотя ни с какими проблеми из-за этих патчей я не сталкивался.
Кстати, а вы не пробовали запись SIP или IAX клиентов? Может это из-за OH323?

В общем, откатился я обратно на 2.6, думаю дело не в ядре (?)
#uname -a

Решил сделать так называемый "asterisk mpg123 fake" - http://www.voip-info.org/tiki-index.php?page=Asterisk%20mpg123%20faking%20it

Заменил его cat`ом и переконвертил mp3-ки в .raw формат.
Теже "яйца", вид сбоку:

То же самое говорит, если звонить с SIP'а.

1. Вам нужен не sip debug a общии дебаг. См. в logger.conf
full => notice,warning,error,debug,verbose

А как себя себя ведет астериск при выполнении команды Monitor() ?

Крайняя мера: пользуйтесь командой strace c параметром -f

а не g729 кодеком это может быть связано ?
какой модудь для него у вас ? у меня была подобная ситуация когда я использовал оптимизированый
модуль pentium3 - когда же взял просто pentium - все решилось
