Asterisk application

We have built an asterisk application to notify restaurants when they receive an online order via our website and? now need to work out how an asterisk application can dial a restaurant phone number and pause long enough to allow the further keying in of a specific option after the introductory greeting has played eg? Key 2 for restaurant. ## Deliverables We would like to develop and/or replace our core Asterisk application in a way that enables us ultimately to have a more sophisiticated IVR experience for our website customers
