Пытаюсь соединить Asterisk с картой TE110P Digium wildcard и Panasonic KX-TDA100RU c платой PRI30 по Е1 потоку.
Asterisk 1.2.6, zaptel 1.2.5, libpri 1.2.2

###zaptel.conf###

Panasonic сконфигурирован как GSIG-Slave

Звонки от Астериска к панасонику не проходят (возвращает код Cause: Unknown (100), class = Protocol Error (6) ), однако в обратном направлении вызовы проходят успешно. С синхронизацией все в порядке.
Дебаг (pri debug span 1) показывает следующее:

===============================================

Насколько я понимаю проблема в сигнализации, а именно в Channel ID, который посылает астериск, т.е. панасоник не понимает его формат (например, строчка "Ext: 1 DS1 Identifier: 1" )

Кто-нибудь сталкивался с такой проблемой? как ее решить?
Или может у кого-нибудь есть успешный опыт связки астериска по Е1, поделитесь конфигами и дебагом.
Спасибо!
