I have a Norstar receiving 2-T1's (48 Channels) from a Meridian-1 Opt 81C. Both sides set up D4, AMI. The Norstar can receive calls but can't make outgoing calls. When a Norstar set tries to make an outgoing call across the T1 trunks, you get dial tone ok but when you dial the first digit you get a fast busy tone. Any clues???
Trunks are set up for Wnk start.
