Regarding the CX600 phones specifically, I was recently asked if the time limit for the dialing string; specifically for dialing 7-digit USA numbers, could be extended.
For example, the user tried to dial (555) 555-5555, looked away from the phone to confirm the number, during the 3-second pause, the dial string had timed out, giving the user this error: "Cannot reach the number as dialed. Please hang up the call and try again."
The request was that the user would like for the time allowed to dial a number to be extended before the call times out.
If the Customer dials the full 7-digit numeric string without pausing, the CX phone does accept the number and successfully place a call.
I walked through the documentation for the CX phones, confirming that this is not a feature nor a setting of the CX phone itself- therefore confirming that the issue is originating within the user's LYNC 2010 deployment.
What I am curious about, is if Microsoft has addressed the issue and if so, is there a Microsoft forum documenting this issue that the user could reference to gain a better handle on the issue when troubleshooting with the Microsoft technician?
the correct forum for CX related issues would be => here <=
Please remember that the CX phones are based on a Microsoft reference design and run a Microsoft Software (Windows CE).
All Software for the CX Phones is provided and hosted by Microsoft and a change to the current design would need to be requested from Microsoft directly.
