yes,
87 & 27 are CDP'd as a DSC to another pbx via tie lines.
the problem is I have over 300 people that use 8770 to access their voicemail (in another pbx). Due to time and other constraints, I'm not able to tell everyone to start dialing 2770 before 8770 goes inactive. So I'm wanting to tell the pbx that if it sees 8770, send it to 2770.
Here is part of the programming;
LD 87
REQ PRT
CUST 0
FEAT CDP
TYPE DSC
DSC 87
DSC 87
FLEN 0
DSP LSC
RLI 2
