LDK300 + Asterisk по SIP Опции

[Beliar]

Здравствуйте.

Мы пытаемся соединить LDK300 + FreePBX 14 через PJSIP транк без авторизации. Сейчас звонки проходят в сторону Asterisk, но сразу происходит отбой в сторону LDK. Настраивали по инструкции из "ipLDK-20/100/300/300E Feature Description
and Operation Manual":
Trunk mode : Make Station 1000~1009 receive incoming call from SIP server(sip.trunk.com)
1. Set Station number as 1000~1009 at ADMIN 105.
2. Set CO Service type as DID at ADMIN 140.
3. Set COLP Table Index as 00 at ADMIN 143.
4. Set CLIP Table Index as 00 at ADMIN 143.
5. Set Call Type as SUBSCRIBER at ADMIN 143.
6. Set DID CONV Type as 1 at ADMIN 143.
7. Set ISDN Enblock Send as ON at ADMIN 143.
8. Set Networking CO Line Type as SIP at ADMIN 322.
9. Set VOIB Mode as SIP at ADMIN 340.
10. Set Proxy Server Address as sip.trunk.com at SIP Attribute 1.
11. Set Domain as sip.trunk.com at SIP Attribute 1.
=> When there’s an incoming call, the Station 1000~1009 can receive call by SIP URI number.

Подскажите в чем может быть проблема и что где можно подкрутить
