VM1188T
802.11b/g VoWifi Phone
The VoWiFI phone VM1188T is designed for
users who need mobility of WiFI and the cost
saving of VoIP. The VM1188T is intended to
help users make SIP calls without the hassle of
turning on your computer. The compact and el-
egant design of VM1188T allows users to make
VoIP calls at work, home, and on campus with
POTS like voice quality
The modulation of VM1188T is based on the
WiFi standard; it is compatible with almost all
standard 802.11b/g access points. With the
VM1188T, users can access to both PSTN and
SIP networks as long as there is a trunking
gateway available at the CO side. With the
easy startup, users don’t have to remember the
SSID or security key of each AP, the VM1188T
stores these confi gurations and will connect
to the access points automatically when boot
up. Paired up with the cradle access point
CAP2316A, users can enjoy the benefi t of
interference free wireless environment through
the implementation of MSSID.
With Accton’s VM1188T, users can enjoy the
benefi t of cost reduction with SIP, mobility with
802.11b/g WLAN, and hassle free installation
with easy startup. The VM1188T is pact with
user friendly features all in a single device.
T
he 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 calls
as 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 ts
Advanced Security
Open Standard SIP v2 Support
The call control protocol of the VM1188T is
based on SIP v2 (Session Initiation Protocol
version 2, RFC 3261) open standard, which is
interoperable with major SIP-based call serv-
ers, IP-PBXs, and other standard SIP-based
client devices.
The VM1188T will support WiFi Protected
Access (WPA) and WPA2 with pre-shared
keys (PSK). WPA supports TKIP while WPA2,
supports AES encryption. WPA, and WPA2
address some of the security risks inherent in
the legacy Wired Equivalent Privacy (WEP)
protocol. Specifi cally, they provide stronger
authentication and encryption than WEP.
Enhanced Power Saving Design for
Extended Standby and Talk Time
With an improved power-saving design, the
VM1188T can be used for a relatively long pe-
riod of standby and talk time. With an extended
life for each recharge cycle, the VM1188T is
available where and when you need it.
Roaming between APs
The VM1188T supports 802.11f Inter Access
Point Protocol (IAPP) to provide STAs with
constant IP-connectivity when users moving
around in the environment of multi access
points. The VM1188T uses L2 Mobility to allow
Stations to roam between APs inside their
Home IP Network.
Industry-standard 802.11b/g
Network Compatibility
The VM1188T allows customers to achieve
cost-saving effi ciency with convergence of
voice and data over a single wireless network.
With the support of 802.11g and backward
compatible with 802.11b, the VM1188T will not
slow down network throughput while running in
a pure 802.11g wireless environment
Exceptional Voice Quality
The QoS function of VM1188T will maintain
exceptional quality in a shared wireless voice
and data network by prioritizing voice to
have higher priority then data packets. The
WMM(802.11e) provides optimum Quality of
Service (QoS) by delivering real time applica-
tion packet with higher priority. The WMM will
recognize the Types of Service (TOS) fi eld of
the IP frame to assign the priority for the IP
frames. The QoS function of VM1188T will
also look up 802.1p tag when VLAN is ena-
bled. By providing preference to voice packets
over data packets on the wireless LAN, this
prioritization of packets helps increase the
probability that all voice packets will be trans-
mitted effi ciently.
