Yealink t21 e2 не распознает входящие. Настройка телефона Yealink SIP для облачной АТС Ростелеком

После того как ip-телефон подключен к сети нам нужно узнать его ip адреса. Узнать его мы можем двумя способами, посмотреть в статусах на вашем роутере или через меню телефона, для этого нажимаем Меню -> Статус . В верхней строке будет написан IP-адрес телефона. Вводим этот адрес в адресной строке вашего браузера(например 192.168.0.28 ).

Откроется Web-интерфейс телефона.

Для входа вводим логин(по умолчанию - admin ) и пароль(по умолчанию - admin ).

Попадаем в Web-интерфейс телефона и первая открывшаяся вкладка будет Статус, отображающее: версию ПО, установленную на телефоне, режим IPv4 или IPv6, IP адрес и другие сетевые параметры, MAC-адрес аппарата, режим порта PC (мост или NAT ) и состояние регистрации SIP аккаунта.


Для начала нужно перевести Акканту во включенное положение

  • В поле «Отображаемое имя » вводим то, что хотим чтоб отражалось на дисплее абоненту которому вы звоните.
  • В поле «Имя регистрации » вводим SIP Auth ID .
  • В поле «Имя пользователя » вводим Sip User Id .
  • В поле «Пароль »вводим SIP пароль.
  • В колонке SIP-сервер 1, в поле «Адрес SIP-сервера » вводим IP адрес вашей АТС

Если все прошло успешно, то вы увидите в поле «Статус регистрации » значение «Зарегистрирован ».

Примечание:

  • Если Вы введете несколько раз неправильно пароль, то дальнейшая регистрация Sip-Аккаунта будет прекращена, так как Ваш IP-адрес попадет к нам в черный список. Для этого Вам надо будет обращаться в техническую поддержку нашей компании.
  • Обратите внимание: Пароль чувствителен к регистру. Это значит, что пароли вида «qwerty» и «Qwerty» абсолютно разные пароли!
  • Если теряется регистрация Sip-Аккаунта или регистрация не доступна, то попробуйте изменить Ваш текущий транспорт телефонии. Для этого зайдите в «Аккаунт» и внизу настроек выбрать вместо UDP – TCP транспорт (или наоборот). Также попробуйте изменить «Период регистрации» вместо 3600 значение 50.
