Hi, kindly i have a Cisco CME v7, i have install and configure E1 Card, and it was working ok. BUT, there is a problem that the operator can recieved only one call on this e1, also when try to dial on the e1 number from the outside you will recieved a busy tone because it was recievd a call on the 1st chaneel. how i can open all the 30 chaneels of the E1?
