Currently the OBiTALK portal only used an one-line input for both OutboundCallRoute and DigitMap. It's a pain once the rule is more than 40 characters. Usually I have to use an external editor and copy/paste the final setting into OBiTALK portal.
One easy enhancement would be use textarea instead of inputtext to allow multiple line of dialplan and digitmap. It should be a relative small code change to ignore all carriage returns in the middle of dialplan / digitmap.
Some further enhancement can also be implemented. For example, a javascript to detect unpaid curly brace or parenthesis would be nice. It will be even better if the javascript can detect more syntax error in the setting.
