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 elegant 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 wireless 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 servers, 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 period 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 application 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 enabled. 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 transmitted effi ciently.
