Имеет быть 'Asterisk 1.4.26.2 built by root @ pcbsd on a i386 running FreeBSD on 2010-02-01 23:28:52 UTC'.
На нем зарегистрирован удаленный шлюз Planet VIP-480FXO, в кот. включен четырехканальный городской телефонный номер.

Кроме того, у астериска есть френд, подключенный по IAX2.
iax.conf:
[ogogon]
username=xxxxxxx

secret=xxxxxxx
host=dynamic
qualify=yes
context=asterisk
insecure=port,invite
allow=all
Если на городской номер идет звонок с френда через IAX2 - звонок неуспешен.

Если же позвонить на вход VIP-480FO и набрать номер, или сделать это с подключенного к астериску по SIP аппарату - результат совсем другой:

В показанном логе первый порт был занят, потому, что именно через него я заходил. Если звонить с внутреннего SIP-телефона - все то же самое, но первый порт сразу дозванивается.
Чем плох IAX2-френд?
Почему направления авто-конгестятся?
Ogogon.
