I have a couple of questions:
1. What bus were you trying to set the DSM to be on?
2. Is it a DSM+ or an old DSM?
3. What logical ports are your IP phones on? (I've seen BCM's before where the IP phone's DN was sitting on the end of a DSM bus instead of on bus 1 or 8. F*0 should tell you the port, for example, 0108 is bus 1 port
