VM1188T802.11b/g VoWifi PhoneThe VoWiFI phone VM1188T is designed forusers who need mobility of WiFI and the costsaving of VoIP. The VM1188T is intended tohelp users make SIP calls without the hassle ofturning on your computer. The compact and el-egant design of VM1188T allows users to makeVoIP calls at work, home, and on campus withPOTS like voice qualityThe modulation of VM1188T is based on theWiFi standard; it is compatible with almost allstandard 802.11b/g access points. With theVM1188T, users can access to both PSTN andSIP networks as long as there is a trunkinggateway available at the CO side. With theeasy startup, users don’t have to remember theSSID or security key of each AP, the VM1188Tstores these confi gurations and will connectto the access points automatically when bootup. Paired up with the cradle access pointCAP2316A, users can enjoy the benefit ofinterference free wireless environment throughthe implementation of MSSID.With Accton’s VM1188T, users can enjoy thebenefit of cost reduction with SIP, mobility with802.11b/g WLAN, and hassle free installationwith easy startup. The VM1188T is pact withuser friendly features all in a single device.The VM1188T VoWiFi phone is compliant with IEEE 802.11b/g wireless standard, and sup-ports SIP for voice applications. VM1188T allows users to make or receive VoIP phone callsas long as users are in the coverage of wireless LAN. Users can enjoy the convenience of wire-less mobility and the cost savings of VoIP without powering on the PC.Features and Benefi tsAdvanced SecurityOpen Standard SIP v2 SupportThe call control protocol of the VM1188T isbased on SIP v2 (Session Initiation Protocolversion 2, RFC 3261) open standard, which isinteroperable with major SIP-based call serv-ers, IP-PBXs, and other standard SIP-basedclient devices.The VM1188T will support WiFi ProtectedAccess (WPA) and WPA2 with pre-sharedkeys (PSK). WPA supports TKIP while WPA2,supports AES encryption. WPA, and WPA2address some of the security risks inherent inthe legacy Wired Equivalent Privacy (WEP)protocol. Specifically, they provide strongerauthentication and encryption than WEP.Enhanced Power Saving Design forExtended Standby and Talk TimeWith an improved power-saving design, theVM1188T can be used for a relatively long pe-riod of standby and talk time. With an extendedlife for each recharge cycle, the VM1188T isavailable where and when you need it.Roaming between APsThe VM1188T supports 802.11f Inter AccessPoint Protocol (IAPP) to provide STAs withconstant IP-connectivity when users movingaround in the environment of multi accesspoints. The VM1188T uses L2 Mobility to allowStations to roam between APs inside theirHome IP Network.Industry-standard 802.11b/gNetwork CompatibilityThe VM1188T allows customers to achievecost-saving effi ciency with convergence ofvoice and data over a single wireless network.With the support of 802.11g and backwardcompatible with 802.11b, the VM1188T will notslow down network throughput while running ina pure 802.11g wireless environmentExceptional Voice QualityThe QoS function of VM1188T will maintainexceptional quality in a shared wireless voiceand data network by prioritizing voice tohave higher priority then data packets. TheWMM(802.11e) provides optimum Quality ofService (QoS) by delivering real time applica-tion packet with higher priority. The WMM willrecognize the Types of Service (TOS) fi eld ofthe IP frame to assign the priority for the IPframes. The QoS function of VM1188T willalso look up 802.1p tag when VLAN is ena-bled. By providing preference to voice packetsover data packets on the wireless LAN, thisprioritization of packets helps increase theprobability that all voice packets will be trans-mitted effi ciently.Hotel(Overseas Traveler)HomeSOHO OfficeEnterpriseInternetPSTNPSTNES4625VG2211iPersonal GatewayWireless RouterWireless IAD Analog PhoneVM1188TVoWiFi PhoneVM1188TVoWiFi PhoneVM1188TVoWiFi PhoneVM1188TVoWiFi PhoneVM1188TVoWiFi PhoneWA6102XEAPWA6102XEAPES4625L3 SwitchServerSIP ServerTrunking GatewayES4512CL2 Switch |
