Cisco Wireless Phones
Cisco Wifi VoIP phones are quickly becoming a standard in many vertical-specific applications, such as warehouse management, hospitality, retail, and healthcare. Cisco wireless phones offer the consistency, feature-rich flexibility, and call quality offered by Cisco Call Manager or Call Manager Express or SIP as well as the flexibility of a mobile phone.
Cisco CP Series Wireless Phones come standard with SCCP protocol, so you will not be able to use them on your SIP-based PBX without the addition of a SmartNet contract. However, if you are running Cisco Call Manager or Call Manager Express, the CP-7921G or CP-7925G may be the perfect Cisco wireless phone for you.
Cisco WiFi phone will support a 2.5mm corded headset. When buying a corded headset for the WIP310 or CP-7921 remember the 2.5mm QD cable.
