ID Asterisk

Asterisk and Planet vgw-400fo

Hi!
I’m having some problems pairing Planet VGW-400FO (FXO) with Asterisk. Situation is as follows:
Asterisk up and running, IP phones set up and internal communication working as should.
Managed to create sip trunk between the gw and asterix, when calling to pstn line phone rings (hot line extension) not showing caller ID, when i answer the call phone goes to please hang up while on the caller side is still ringing.
on the outbound side when trying to call to the outside trough trunk i recieve all lines are busy message.
really stuck on this for quite a while, any help appreciated.
