Custom voicemail system demonstration

This is a rather long overview of a custom voicemail system I made. Tried to get through everything (you may notice I had a list open in Notepad, yet didn't follow it) but there's a few things I forgot to mention/demonstrate: -You can access your mailbox remotely from another telephone by dialing 1, the system will prompt for your number and your password, then present the same user menu as if you were accessing it normally. -I forgot to show the stutter dialtone message waiting indicator on the analog phone, but it works exactly the same way as a standard phone line does. -The "call hangup messages" option in the mailbox settings allows you to receive a message even if the caller hangs up without leaving one. It'll say "the caller hung up without leaving a voice message" when reading back the message in this case, it'll still allow return calls and such. I have seen this option on a few PBX voicemails in the past, I think it was intended for salespeople or anyone else that would want an email sent whenever they miss a call. -The "long pound" hangup feature I am using for return calls does not have to disconnect the call when using TCL IVR 2.0. In VoiceXML it can only be used to terminate a "transfer" element, but if you want to use it for some other function TCL will allow you to do so. This is primarily written using VoiceXML, it's like HTML but for voice applications rather than webpages. Super powerful and I'm not using all of it's capabilities in this demonstration, the Cisco "VoiceXML Programmers' Guide" and Dialogic's online help for their XMS platform are great references for it. I'm using ASP Classic to dynamically generate the XML documents, SQL Server to store information, and a little bit of C# for some things. All the VoiceXML documents are served to the Cisco gateway through an IIS web server on my local network. I am also working on a "visual voicemail" service for this which can be accessed as an XML service on the Cisco IP phones, will likely make a video demonstrating that in the future as well. Will definitely be doing a video on ISDN phones in the future, It was pretty hard to find information on what things can support them. I have had the best luck with them using an Adtran Atlas 550, I still need to do some further experimentation and testing with connecting them to a Cisco router. An appropriate power supply for the Lucent 7507 and most other BRI phones is the Lucent 1151, it uses a straight-through cable with 1:1 pin mapping to the phone on the output side. Regarding the PSTN access, I was using a DISA or Direct Inward System Access application which I made to dial back into an internal number on my system. The DISA is password protected, and the 208 number which was used to originate the call just reaches my alarm receiver, neither of which I am concerned about having publicly displayed. No need to bother with trying to call them :P 0:00 Software overview 2:55 Cell phone call redirection system 4:04 Integration with other phone systems 4:55 Overview of phones being used for the demonstration 6:59 Overview of the backend equipment 9:19 Leaving messages 13:22 Reviewing messages 17:00 Leaving a message over the PSTN 19:39 Message options, and placing return calls 27:14 Mailbox settings 31:56 Setting up a new mailbox 34:37 Reporting a message for abuse
