AddPac GS1002 нет запросов на регистрацию

Пытаюсь связать AddPac GS 1002 и Asterisk.

Проблема в том, что AddPac не посылает запросов на регистрацию на Asterisk. На стороне Asterisk'a слушаю и Sip debug'ом и tcpdump'ом - тишина.

В iptables все чисто...

Вот только пинги с AddPac'а на Asterisk проходят какие-то странные с задержкой 0 мс:

Вот конфиг AddPac:

Причем вначале запросы были, но пока разбирался чо к чему, пропали, и я не могу их заставить снова появиться...

Может будут мысли где копнуть?
