Folks, as you see I have become involved in a CP 150 using all four ports and 4 stations (313,314,315 & 316). Sometimes when call comes in and through CCR Tree #1, callers will get "Invalid Number". It seems to be very intermitent but annoying. Ext 313 is programmed in the system as the voice mail port from the 0x32. The question is how should the other stations (314, 315 & 316) be treated: 1) using Busy forward (in the 0x32)to 313 or maybe in a hunt group with the other exts. 2)Or, does the CP 150 exclusively handle the routing of the calls from 313 thru 315? I've tested both the 0x32 exts and checked to be sure the 150 is seeing the stations (all 4 LEDS are lit). What am I looking over please?
