Check telephone configuration
¥ Verify LD23 configuration: AST=YES, ISAP=YES, and
VSID=VAS ID assigned to ESDI or MSDL link.
¥ Target DNs must be configured as AST if an application wishes to
control the telephone. Use LD10 or LD11 as required for telephone
configuration.
¥ Each telephone must be configured with the appropriate class of
service or feature keys that the application tries to invoke on that
telephone. For instance, if the application tries to transfer a call, the
telephone must possess a TRN key.
¥ Make sure GRPs, VSID (LD15), and IAPG (LD10/11) are set correctly
for status change messages. (Verify assignments with the application
programmer.)
¥ Make sure DNIS is defined correctly (LD14, LD15, and LD16).
