Music from hold

Hi guys,
I’m building a program in VB.NET with AsterNET that will call a group of phones and send them to an extension that will put them on hold.

    Dim test As New Action.OriginateAction
    test.Channel = "SIP/2035"
    test.Exten = "1111"
    test.Context = "default"
    test.Priority = "1"
    test.CallerId = "2035"
    test.Timeout = 3000000
    conn.SendAction(test)

This will call ext 2035, when answered, it will call exten 1111
My question is
What is the best way to do it for 70 phones at once?
Thanks

Curry your list replacing 2035 with the actual extensions.

Sorry for the late response,
I did not understand

Reproduce the list, but instead of using 2035 every time, replace the 2035 with your actual extensions.

Since 2035 is the main extension that will be calling all the other extensions, is this what you mean?

Or will it be a better idea to create a paging group, lets say 900, with all the extensions that I need and do this?

Thanks
