HI,
is it possible to make conference call on sv8100 for co trunks, and i shouldn't be able to enter into the conversation by pressing the trunk key button which blinks after i transfer?

The procedure requires use of a soft key.
After completing the first call press TRF, then place the second call. Look for a CNF softkey then another softkey joins the two conversations.
