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.

  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. 

  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.

  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.

  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

  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.
