I am not sure if this is even possible, but am hoping for suggestions. We have an IP Office, with Voicemail Pro, system. Our Voicemail Pro is running on a Windows XP computer. I would like to be able to develop a VB program that would run on multiple computers connected to the same LAN as the voicemail server and IP Office system. This program needs to be able to "trigger" our paging extension that is already setup in the IP Office system. So that when a button is pressed (or some event) on the VB application it signals a tone over our paging system. Is this even possible? I know there is some vb scripting that can be done in the Voicemail Pro software, but I'm not sure how to use that on a computer not running the Voicemail Pro software. Or can I install some type of client software on these computers, that could be called from a VB app? Thanks.
