SpectraLink DECT cordless phones

SpectraLink DECT cordless phones are more scalable than Wi-Fi phones because up to 80 of these phones can be simultaneously used in a 10 MHz wide band in the 1.9 GHz range. These phones terminate to a box that supports 8 phones at a time and connects to your VoIP infrastructure using SIP. Wi-Fi phones that use SpectraLink SVP (SpectraLink Voice Prioritization) wireless QoS can only support around 12 phones in comparison but allow you to use your own Wi-Fi infrastructure.
