Norstarboy,
I am 100% in agreement with you. I hate the IPO and I have done numerous installs since Avaya took over. The BCM was probably the best system around and still is. As far as Spydur goes, I signed up with them a while back. All they have is basically Asterisk Now but they cut out the features and charge you for them. I have started selling SipXecs. Its an open source and is the core for the SCS. With the purchase of a good server I have been able to support over 500 users and SIP trunking. No nonsense of purchasing licenses for every user, voicemail seats or ACD. Everything you need is already there and ready for you to use. Also teleworkers can work from behind a NAT so no crazy setups are needed. Only negative is you have no support but the forum is better then any tech support you could find.
