[Freeswitch-users] How to start IVR script via dialplan by making an outbound call

Hi folks, It's easy to start to run IVR script by an inbound call on FreeSwitch. However, I don't know to start to run IVR script in the following case: I'd like to run an external client application which will ask FreeSwitch to make an outbound call to a mobile phone number, when the phone rings, someone picks it up and then she/he starts to interact with FreeSwitch normally like an inbount-call initiates to run IVR script. Could anyone please give me some advice? Thanks x.k.
