[asterisk-dev] creating telemarketing system

[ultra hold]

Hi!

Please, help me find the way for create telemarketing system using AMI.
For example, there is one operator and 5 phone numbers for calling.
I need to create this call process:
1) Asterisk call to operator and start playing music in a channel
2) Asterisk consequentially trying to call the phone numbers
3) If phone number answer, asterisk stop playing the music and connect
operator to call.
How can I create this scheme using AMI?
If you have sample, please give me one.

Regards.
