I have found the solution:
/*Collect CLID into variable.*/
ASSIGN CLID TO CBR_InboundNumber_cv
/*Convert variable of type CLID to string*/
CONVERT CBR_InboundNumber_cv TO STRING c_sip_digits_str_cv
WAIT 2
/*This GIVE IVR command plays back the CLID*/
ASSIGN c_play_only_gv TO voicexml
ASSIGN c_sip_digits_str_cv TO varsstr
ASSIGN "YourPhoneNumberIs.wav+%i0" TO prompttoplay
GIVE IVR SERVICE URI serviceuri WITH VXML TREATMENT voicexml PARAMETERS prompttoplay, varsstr
WAIT 2
DISCONNECT
