OSLEC

[Reader]

Дано: "Elastix 2.4.0 32bit" включен в TDM PBX потоками Е1 платой c аппаратным эхоподавлением. Обе PBX настроены и работают расчудесно совместно круглосуточно. Вчера днём общался с одного своего телефона с TDM PBX с другим абонентом этой же TDM PBX через "Elastix" (участвовал в конференции). И обнаружил, что в эфире стоит какой-то слышимый треск и шум, а порою даже слышно эхо ! Обратил свой взор на настройки шумоподавления Hardware Detector -> Configuration of Span, и обнаружил напротив каждой СЛ значение "none" !!! Дорогое эхоподавление попросту отключено !! Сел. Дотошно на каждой СЛ включил. Сохранил. Более эха не было. До сегодняшнего утра. Утром просто загляную на те же самые настройки потоков - опять "none" !!! Шайтан !! Опять сохранил. Опять эхо исчезло. Радоваться бы. Но вспомнил, что где-то неделю назад видел своими очами точно такую же проблему и точно так же с нею боролся !.. Вопрос - почему такое происходит ? Digium Диджиумовский (родной, из Американии). Что сделать, чтобы отключение аппаратного эхоподавления более не происходило !?
Пока не опубликовалось, добавлю: Сейчас прописал по входящей связи возможность звонка в конференцию из TDM по DAHDI на Elastix ещё одного абонента с уникальным А-номером, на всякий случай заглянул в обсуждаемые настройки - опять "none" !!!! Что делать ?..

гадаем на кофейной гуще

смотрим логи, не было ли релоад служб apache, dahdi, asterisk

[Reader]

Хороший вопрос. Сейчас сделал эксперимент. Эластик работает. Зашёл в gui настроек потоков, опять прописал везде где нашёл OSLEC в каждой СЛ. Затем вышел из этой вкладки, зашёл во вкладку Reports, затем во вкладку System, затем опять в Hardwsre Detector -> Config. of Span #1 - и что бы Вы думали - "none" !!!!!!! Лезу в логи Астериска и вот они, вполне безобидные, никаких там релоудов:

[Reader]

... выходит не в релоудах дело-то ... Тогда в чём ?..

[Reader]

Повторил только что проделанную операцию:
All trunks -> OSLEC.
-> Reports
-> System -> HardwareDetector -> see "none" for all trunks !!!!!!!
-> drink Vodka ?

[awsswa]

тогда делаем логичный вывод

то что в вебке - не сохраняется, значит надо прописать ручками в файл настройки dahdi

[Reader]

Дык начинающий я - самому не разобраться. Вот захожу я через web-interface в PBX -> Tools -> файл dahdi-channels.conf. Там - следующие настройки:
; Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" (MASTER)
group=0,11
context=from-pstn
switchtype = euroisdn
signalling = pri_cpe
channel => 1-15,17-31
context = default
group = 63

; Span 2: TE4/0/2 "T4XXP (PCI) Card 0 Span 2"
group=0,12
... и т.д. остальные Span'ы по образу и поодбию 1го ...

А как правильно прописать постоянное включение аппаратного эхоподавления-то ?

Ещё смущает фраза в самом верху этого файла:
; Autogenerated by /usr/sbin/dahdi_genconf on Tue Dec 3 11:38:58 2013

# Global data

вот эта надпись mg2 говорит о включенном подавлении,
если собрано с поддержкой oslec, тогда так

echocanceller=oslec,1-15,17-31

to awsswa:
Спасибо. Что-то не нашёл я такого файлика в своей машинке. Есть отдалённо похожий по содержанию файлик /etc/asterisk/chan_dahdi.conf.elastixsave:

[trunkgroups]

[channels]
context=from-pstn
signalling=fxs_ks
rxwink=300 ; Atlas seems to use long (250ms) winks
usecallerid=yes

;Uncomment these lines if you have problems with the disconection of your analog lines
;busydetect=yes
;busycount=3


immediate=no

#include dahdi-channels.conf
#include chan_dahdi_additional.conf


Но он ли мне нужен - я пока не пойму. Потому что де-факто пока настроил каналы на включение OSLEC и пролистал 3 вкладки в Elastix, у меня из 4х потоков эходподавление почему-то осталось лишь на 3х !!

Что наверное не есть совсем хорошо. Вот ежели бы все 120 channels весело писали бы "Oslec" - я был бы счастлив. А то через GUI попытался прописать эхоподавление на 2м потоке Е1 - на 1м эхоподавление отвалилось ... Шайтан какой-то ... Куда б прописать железно "Oslec", чтоб он всегда был включен у всех 4х потоков ?..
Заранее благодарен за вар-ты ответа.
... Извините, а сразу уж бы и ликбез - а чем отличается "Oslec" от "Mg2" ? И мне-то который нужнее ?
