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:

PING 192.168.0.11 (192.168.0.12): 56 data bytes 64 bytes from 192.168.0.11: icmp_seq=0 ttl=64 time=0 ms 64 bytes from 192.168.0.11: icmp_seq=1 ttl=64 time=0 ms 64 bytes from 192.168.0.11: icmp_seq=2 ttl=64 time=0 ms 64 bytes from 192.168.0.11: icmp_seq=3 ttl=64 time=0 ms 64 bytes from 192.168.0.11: icmp_seq=4 ttl=64 time=0 ms --- 192.168.0.11 ping statistics --- 5 packets transmitted, 5 packets received, 0% packet loss' round-trip min/avg/max = 0/0/0 ms 

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?
