I am having an issue to activate line reversal on LS trunk on Mitel 3300 ICP CXi. I am receiving analog trunks with line reversal from the local ISP. I activate the reversal on the circuit descriptor but, it's not working. When forwarding a call to a fixed line or mobile the line will stay busy untill i unplug the telephone behind the 3300 ICP.
Can someone help me? Maybe 3300 ICP rel 9.0 don't support line reversal ?
Thanks,
G
