Chaning IVR to forward to an extension

Say I have IVR setup so when a customer calls the main phone #, and get a AA voice prompt saying “press 1 for sales, press 2 for accounts”. And when they press 2, it forwards them to extension 300

So my question is - how can I change this so pressing 2 forwards to extension 221? And it is possible to just change some config so that anybody that dials extension 300 (or is forwarded to extension 300, by the IVR) goes to extension 221 instead.

Cheers,

IVRs are a derived feature in Asterisk. You need to ask the person who wrote the dialplan that implements them or look at it yourself. You can contact the people who know about that for FreePBX at freepbx.org/forums/

By derived, I mean that Asterisk itself does not implement IVRs but you can use Asterisk dial plans to implement them.
