I have a Rel 3.0 BCM 50 with a BRI-ST4 MBM connected. I have 4 * BRI lines from network provider. I am having issues with the BRI # 1. A trace of a dropped call is shown here. You can see at 11:24:08 the BCM sends an ALERTING_CC message, but then the network regenerates the call after 4 seconds. Eventually the call fails. Network techo has gone on site and voice tested the NTU by dialling in and out to his test phone.
The strange thing is that the other 3 BRI circuits on the MBM work perfectly.
I am still suspecting NTU or network programming.
Any ideas on where to go from here.....
