hi,
to change the no. of rings before a phone forward or disconnects , you need to change the RCO option in the phone properties(Ld10/11). The no. of rings is configured in ld 17. Prompts are
CFNA yes
CFN0 4
CFN1 3
CFN2 5
Whateever is configured in your CDB. You can print CDB in LD22.
Hope it helps
Cheers
