direct inward dialing configuration

I have deployed a CALL MANAGER EXPRESS at a client, but I have a problem transcoding sda. Here is the problem:

The customer has a slice of external numbers (sda) from 338890820 to 338890850 with the head of line 338890820 AND extensions as 1820 to 1850;

I applied the "pattern dialplan-1 3388908-length extension .. 4 .. 18 extension pattern" in telephony-service. But when I call 338890820 eg it does not ring on the 1820 so forth.

Thanks for a solution!

Re: direct inward dialing configuration

Hi, tha should be:

dialplan-pattern 1 3388908.. extension-length 2 extension-pattern 18..

Note that very likely you will also need "isdn overlpa-receiving" under all ISDN ports.

If that doesn't work send output of "debug isdn q931" with "term mon" for an incoming call.

hope this helps, please rate post if it does!

Re: direct inward dialing configuration

OK! I was misled about the syntax before. The syntax that I had actually composed:

dialplan-pattern 1 3388908.. extension-length 4 extension-pattern 18..

Thanks for your confirmation!
