Связка Alcatel OXO и Asterisk (FreePBX) - обе за NAT

Добрый!

Пытаюсь реализовать следующую схему работы:

IP терминал -> Alcatel -> Asterisk -> PSTN

Alcatel и Asterisk (Ver. 11.14.1) находятся за NAT в одной сети. Cоздал транк, где 192.168.2.252 - IP Alcatel:

context=from-internal
host=192.168.2.252
insecure=very
type=friend
dtmfmode=rfc2833
disallow=all
allow=alaw&ulaw
nat=force_rport,comedia
directmedia=nonat

И хочу, чтобы IP терминалы, подключенные к Alcatel могли использовать внешние транки Астериск. Собственно, звонок проходит, но когда вызываемый абонент "поднимает" трубку, то происходит обрыв соединения. В логах следующее:

Если я все правильно понял, то Астериска после выполнения звонка пытается связать напрямую Alcatel (которая за NAT) и абонента, игнорируя nat=force_rport,comedia. Или я неправильно понял суть этой инструкции?
