We have CCM with version 4.2(1) and 300 IP phones. The extension numbers are in the range of 101 - 399. We also have route patterns like 2xxxxxxx, 24xxxxxx etc. for the outgoing calls through the PSTN. So now say from the extension 145 the user tries to dial 24660143, the moment user dials the 3rd digit (i.e. 246) the call lands on the extension 246.
So how to overcome this problem, can someone help me on this...
