CGP с лицензией на *.mail.mydomen.ru установлен на 192.168.0.251 и 192.168.0.252. Вот, как это выглядит в сети:

$ host mail.mydomen.ru
mail.sirena-travel.ru has address 192.168.0.251 mail.mydomain.ru has address 192.168.0.252

$ host mx1.mail.mydomain.ru
mx1.mail.mydomain.ru has address 192.168.0.251

$ host mx2.mail.mydomain.ru
mx2.mail.mydomain.ru has address 192.168.0.252

Все адреса внутренние, NATа пока нет. К voice-port 0/1/0 на cisco-2811 подключена обычная городская телефонная линия.

А вот, что получается при попытке позвонить на эту линию:

Перебор параметра "codec" для "dial-peer voice 2 voip" ни к чему не привел.

Подскажите, пожалуйста, как заставить CISCO передавать правильно звонок, а CGP его принимать на PBX?
