Sorry, 3-way conference call is the max in SP1. I feel bad you spent 25k on a new system a few years ago. Costco now sells RP under 2k today.
We are shipping RP SP1 in a week or so. You can import contacts from Outlook/BCM to RP so you can either click the RP Assistant or press the blue button to voice dial. We don't support direct click to call from Outlook in SP1 yet. We have started working on RP 2.0 and stay tuned for many more exciting features from the team!
When we started RP, our vision was simple: to provide a telephony solution that is so easy that every small business customer can set up the phone system just like a printer/fax. RP provides IP PBX, Voice Mail, IVR, and CTI function ina simple box without any moving parts (i.e. no hard disk, no fan... for increased reliability). You can forward the call to cell. You can have a 3-way conference call, and you can even turn your cell phone into a PBX extension so even if you are not in the office, you can call RP and use the VOIP lines for international call.
When I drive home, I have my conference call to Taiwan or China. I never used my cell phone to call internationally. I always call RP first (a local number) and use my voice to dial out to people in my contact list in the car. My cell phone has no fancy voice command but I have a better solution no matter what kind of cell phone I have...
I have also set up the systems for my house. I have a beta ATA that connected my cordless phone to the RP system. One morning my wife asked me to call my sister, I grabbed the cordless phone to make a call. She asked “Didn’t you need to find her phone number first?”. I smiled and pressed the “Blue Magic Button” and said “Call my sister at home”. She was shocked and that was the moment she said RP is really cool…
I am very proud of what we have done for RP.
