Я хочу подключить (для обучения, ничего серьезного) два сервера asterisk через ISDN PRI. Первый сервер будет действовать как "telco", поэтому это pri_net, второй сервер - cpe, поэтому я буду использовать pri_cpe.
Карты есть
pbx1-net: Digium TE205P pbx2-cpe: Openvox D210P
Оба сервера/АТС используют Debian 11 и драйверы dahdi 2.11.
В сети pbx это dahdi/system.conf

На стороне pbx-cpe файлы идентичны, за исключением /etc/dahdi/system.conf (1,1,0 — это 1: диапазон, 1: источник синхронизации со стороны pri_net, 0: кабель 0-133 фута).

Остальные два файла идентичны, за исключением pri_net, который стал pri_cpe.
А теперь проблема:
На pri_cpe bpx отчет cli в порядке

Также отчет о припасах в порядке с обеих сторон

Я настроил extensions.conf для звонков через pri с обеих сторон

Когда я пытаюсь сделать звонок на обеих консолях появляются эти сообщения об ошибках

Я пробую эти решения
Solution number 1: the card is broken, I bought another PRI card = FAIL
Solution number 2: change the pci slot of card pri_net side, and / or pri_cpe side = FAIL
Solution number 3: use a different dahdi version = FAIL
Solution number 4: use pridiallocalplan=unknown and pridialplan=unknown = FAIL
Solution number 5: revert pri_net pri_cpe roles = FAIL
Solution number 6: try another crossover cable = FAIL(I try 3 cables, two bought, one made by me, and all tested with network tester)
Solution number 7: reboot = FAIL
Solution number 8: remove the analog card from pci_net server = FAIL
У кого-нибудь есть предложения? Спасибо.
решение1
Решение найдено. Кабель был плохой, я следуюэто руководствона youtube для создания кабеля PRI и работает отлично, мне нужно было только перезагрузить машину pri_net.
