Short Interdigit Timer Issue?

[wildcard100001]

Running CM 5.2.1 SP6

I'm not seeing that the short interdigit timer is working when using Multi location dial plan and dialing digits.

Scenario:
CM 5.2.1 - SIP Trunk - Session Mgr - Sip trunk - Evolution Server - H.248 - G450 Gateway - T1 Xover - NEC PBX

CM 5.2.1 has Multi-location dial plan enabled where each extension is 6 digits but can dial locally with 4 digits.

When dialing the NEC at 81xxxx.. sites on CM 5.2.1 that have xx81xx extensions defined get dead air then an off hook dialing time out. Works if dialing 6 digits.

I'd expect if no further digits were entered the PBX would insert the extension prefix (via UDP L2 and location method) and route locally as it normally does... however it's not.

Why doesn't short interdigit timer work? Anybody else experience this? How did you fix it? Any ideas?

I could dial the aar access code... which works but not ideal.

When I enter 81xxxx 6 digits and 8xxx 4 digits it breaks (--into the dial plan analysis). I'm realizing that I have this problem everywhere though luckily not many in actual user extension ranges.

Thanks,

Wildcard (thinking I'm going to need to force everybody to dial 6 digits or give everybody the AAR access code for "those" sites.)

I was able to correct this issue... such a simple solution.
In dial plan ana I had (not working):
8 4 ext
81 6 ext

To correct the issue and use inter digit time out I did:
8 4 ext
81 4 ext
81 6 ext

The caveat is that users in an extension range of xx81xx will have to wait for the interdigit timer to expire before routing (set in my system to the minimum 3 seconds)when dialing 4 digits within the 6 digit site.
