Even if i try with 3 CO lines, and use
Ext 107 and 108 for VM, its not going.

2 calls in Q, when line 3 rings the caller gets:
This line is busy, if you would like to hold, press 1 otherwise press 2.

i would like this to change to a 'auto hold feature' with call queuing instead of 'if you would like to hold..'
