I'm not crazy.....I'm not crazy. I just added a slt (only one on system). Other than trunks, it works fine. I put the trunks in a trunk group '9', set them as pbx, even put the trunks on ff keys for the slt. On that phone or any other, dialing 9 shows 'BUSY'. I looked through all 64 trunks and verified that no other was in trunk group '9' and that none of the chosen trunks were private. - Pete
