Hello.
I have test dial-plan with my СМЕ 3.2:
-----------------------------------------------
There are 100 dial-line extentions (DNs) 3XX (300-399)
and an outbound dial-peer for local calls to PSTN number 3636308 (h323-trunk to a Gatekeeper):
dial-peer voice 3 voip
destination-pattern 3636308
session target ras
dtmf-relay h245-alphanumeric
codec g711alaw
no vad
and one of CME hidden dial-peers:
dial-peer voice 20064 pots
destination-pattern 363
huntstop
progress_ind setup enable 3
port 50/0/64
The problem: When I try to make an outbond local call to PSTN number 3636308 and start dialing 3-6-3- the call immediatly routes to ext. # 363.
OK, let's check an output of "show dialplan number 3636308" command:
The outgoing dial-peer mentioned above matches BEFORE the ext.#363 dial-peer. BUT the call routes to dial-peer 20064 w/o analizing a depth of the prefix 3636308.
The Question is: Why this happens?
Thank you.

Matching Outbound Dial Peers:
-----------------------------
DID (Direct Inward Dial) Case
On DID calls (also referred to as one-stage dialing), the setup message contains all the digits necessary to route the call and the router/gateway should not do subsequent digit collection. When the router/gateway searches for an outbound dial-peer, it uses the entire incoming dial string. This matching is by default variable-length. It is not done digit-by-digit because by DID definition, all digits have been received.
Non-DID Case
This case is also referred to as two-stage dialing. If DID is not configured on the matched incoming dial-peer, the router/gateway enters the digit collection mode (digits are collected inband). Outbound dial peer matching is done on a digit-by-digit basis. Hence, the router/gateway checks for dial-peer matches after receiving each digit and then routes the call when a full match is made.
It looks like my CME router matches dial peers in the Non-DID mode - hence the problem. How to change the mode to DID?

Probably is't impossible change the dial peer matching mode in my case, because of lack of E1/T1 or FXO voice port, where direct-inward-dial command can be issued.

...But it is possible to change the dial plan it self from extentions 300-399 to 001-099. After mentioned changes the new dial plan with direct dial (w/o trunk access code digit) of local, national and international numbers works OK.
