Both systems have been rebooted,the lines in Blocb are 047-078. I have the route table built with route 002 using Blocb, with a destination code of 8. This is because both sights have the same DN number range. We are using the data connection between the sites for the IP Trunking. I might add that I have another customer that has a BCM400 and 2 BCM 50's in place and I have them connected via IP Trunks and working no problem. I have used the same programming outlay from the BCM400 on the BCM 450 as in using the same programming guides. Also we maintain the network for both customers, so I have support on the network side as well. So I wasn't sure if this was something with the BCM 450 or not. I have also installed all the latest patches on the BCM 450. I hope this gives you enough information. Thanks again.
