Overlapping DN in CME

Unanswered Question

Here's a tricky one:

The config is a CME 4.1.

I have a senior's home that a resident has the extension 3682 (call him Bob).  I have another resident (call her Sally) that wants to call a PSTN number 368-25## (call this person Fred).  As soon as Sally calls Fred, she gets Bob due to the fact that Bob's DN (3682) is part of the E.164 number.

My question: Why is this?  I have the inter-digit timeout set to 4 seconds.  Shouldn't it wait before connecting the call?

Is there any way around this?

Note that the residents don't want to have to do a dial prefix (i.e. .9).  They are elderly, and it confuses them to have to dial a prefix (they keep saying "we didn't have to before).

Any thoughts?

You cannot have averlapping in cisco telephony no matter the interdigit timeout. Otherwise, an unnuncessary delay would be introduced for internal calls, and people doesn't want that.

If they do not want to use an access digits, number extensions starting with 0 or 1.

If thye do not want that neither, then CME is not the right product for this customer.
