Incoming settings on sip trunk

Hi Guys
i am trying to set up a sip trunk between an AsteriskNOW server and a LG iPECS UCP on the same network

at present i can dial from the Asterisk server to the iPECS and this is working fine but when i dial from the iPECS the call is dropped instantly i hit send.

so i am looking for the settings that i need to put in the incoming settings of the sip trunk

this is what i have set in the trunk outgoing settings

host=192.168.207.8
type=friend
context=from-internal

i have tried putting this in the incoming settings of the sip trunk but no joy calls still fail

Please provide logs of the call attempt
