I am trying to make somthing like a clall cenet and i am stuck in one of the cases..

USing

SIP Express Server from the CVS and SEMS from CVS

wont to create outgoing call and start an IVR script

Somthing to create call (A) | --> SER -->SEMS--> called person (B)

Ideia is to make a call and start an IVR to Person B

i know that SER cant do that

but what about SEMS or SIPUMS or asterisk or ok i can make a some SIP client in back ground and told to him to make a call but how to start an IVR to client B not to client A.
