9. Поместить в отчет по одному диалогу для каждого сценария (всего – 6). Подробно, с исследованием сообщений SIP, включая SDP содержимое. Обратить внимание на адреса и порты RTP-потока.

10. Восстановить картину звонка по сообщениям SIP. Нарисовать схему прохождения звонка.

Рисунок 3.19 – Схема регистрации, начала и окончания звонка

Содержимое отчета

1. Схема соединений ПК и UA пользователя с IP адресами

2. Скриншоты настройки фильтра в Wireshark

3. Скриншоты результатов работы фильтров для 6 сценариев

4 ЛАБОРАТОРНАЯ РАБОТА №4
Изучение интерактивного голосового
меню (IVR) и AGI-скриптов.

Цель работы: настроить и изучить возможности сервера Asterisk для создания интерактивного голосового меню (IVR). Научится создавать голосовое меню и настраивать его работу. Научится создавать AGI скрипты и изучить на практике работу AGI-скриптов.

Задание на лабораторную работу

В ходе выполнения лабораторной работы необходимо создать голосовое меню, согласно варианта задания. Настроить сервер Asterisk для записи звуковых сообщений. Проверить работоспособность полученного IVR. Написать простейшие AGI скрипты, которые произносят произвольно введенный символ. Проверить работоспособность полученных скриптов.
