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!
