Adding delay via the FreePBX GUI

General Help
1

On TB 1.2.2 with a Digium TDM400P, I need to add a 0.5-second delay when dialing out to the PSTN, lest the first few digits get truncated.

I can manually add a “w” before the extension in extensions_additional.conf, and that works fine, but that modification gets clobbered every time I change something via FreePBX.

Is there some way of adding the delay inside of the FreePBX GUI?

thanks much

what about putting the “w” in the prefix box?
