I have a ndk9000 system which receives calls on tli cards. I know they are 3 digits cause they are send for a pabx.
The customer wants to change am extn number on the ndk9000 from 544 to 546. I have had a look at the programming 1-1-22 doesn't exist.
How else can received calls be send to extns.
I have change extn 544 to 546 I get busy when rung. I have set the remote end to send calls for 546 to 544 this works fine.
any help appreciated thanks
