So here's the logic:
the BB is the defacto corporate standard for secure, data mobility. Ascendent brings corporate secure voice mobility to any device (including BB's), any phone (landline, VoIP, WiFi, Cell). It pushes voice calls from your corporate phone extension to any device, anywhere. It can simultaneously ring up to 3 phones, and when you answer the call, you have all the features you have from your office phone: hold, transfer, conferencing, etc. If you don't answer, the call goes to your corporate voicemail system.
You can also call back into the Corp. phone system and get dialtone to 4 digit dial to other extensions, etc.They have cool conferencing features: "GetMe" conferences, where you can schedule a conf call, and at the selected day and time, the Ascendent system calls each participant and brings them into the conference.
The upside for highly mobile workers is that they now have one number, one voicemail. People trying to reach you only need to know that one number, and Ascendent finds you at any phone, anywhere.
They also have full audio conferencing, notification and business continuity features. Corporate IT should see this as RIM becomes the corporate voice and data mobility platform. Integrates with all major PBX and IP-PBX phone systems. Also, any phone will work with the system, and you use the dialpad to navigate the features of the system: *1 to add another party to the call, etc.
It's extends realtime productivity by enabling voice and data to reach you, instantly. Also, add Instant messaging to your devices, and presence (state change) to control how, if, when calls are even offered to you.
This extended functionality positions RIM to compete against Avaya, Nortel and Cisco on the Corp. phone side, and Microsoft on the data side.
Very cool stuff.
