>>>I am planning on purchasing a product that will let me send messages out to people, which can either be text to speech, or recorded wav files. I was wondering if we should go VOIP, and if anyone here has any experience with this. I would like to be able to do 32 lines. I would hope I could put a 32 port switch up and go from the ports on the dialogic boards out to the internet. Does anyone know if this configuration is possible, or am I going to have to plug 32 phone lines into the boards?
