Inter-Tel is a far better than the Toshiba. How long has Toshiba been offering point to point networking, IP networking, IP phones, adv call center features? Toshiba just hooked up with Taske and OAISYS. Inter-Tel has been providing high end voice solutions for years. Unified messaging, CTI, ect. rocks on the inter-tel platform. Full Duplex speakerphones. Toshiba charges a fortune for a feature that is built into the Axxess.
