to set these features exactly (and assigned to the right keys) so that the PBX
Integration Board and the Dialogic
®
Unified API can function correctly.
• All PBX Integration Board ports on a ROLM system must be
programmed as ROLMphone 400 telephones.
• LINE must be programmed on Feature Key 09, and the ROLMphone
must be programmed to select this line when going off-hook.
