9-1-1 – Emergency Access

vTone/PBX VoIP 9-1-1 Service Limitations

Vianet provides VoIP 9-1-1 service to every vTone/PBX subscriber. VoIP 9-1-1 service is different from
Enhanced 9-1-1 service (service provided on a traditional phone line). VoIP 9-1-1 service limitations
include the following:
VoIP 9-1-1 service may not be available in an electrical power outage and will not be available during a
broadband Internet outage.
VoIP 9-1-1 calls are sent to a call centre for screening and routing to the correct emergency response
center (also known as the Public Safety Answering Point or PSAP). This is different from Enhanced 9-1-1
service where the call is sent directly to the appropriate PSAP. Due to the "nomadic" nature of vTone/PBX
service (service can be moved to any location with broadband Internet access), a caller must identify
his/her location to the 9-1-1 call taker in order for the call to be routed to the correct PSAP and for
emergency services to be dispatched to the correct location.
Subscribers of Vianet's vTone/PBX service are required to ensure that all potential users of the VoIP
service understand the 9-1-1 service limitations identified in this notice.

Limitation of Liability

Neither Vianet Internet Solutions nor their employees shall be held liable for any claims, losses, damages,
penalties, fines and expenses and you hereby waive any and all such claims or causes of action arising
from the absence, outage or failure of the VoIP service, including the inability to be able to dial 9-1-1 to
access emergency personnel.
You agree to defend, indemnify and hold harmless, Vianet Internet Solutions and its employees and any
other third party service provider who furnishes service to you or to Vianet in connection with VoIP
services, including 9-1-1 service from and against any claims, losses, damages, penalties, fines and
expenses (including, without limitation, legal fees and expenses), by or on behalf of you or any third
party or user of your VoIP local line service relating to the absence, outage, failure or degradation of
voice quality of the VoIP service, including the inability to be able to dial 9-1-1 to access emergency
services, the inability to complete a 9-1-1 call, the inability to correctly route a 9-1-1 call to the
appropriate PSAP or to correctly dispatch emergency services to the location from which the 9-1-1 call
originated

User tips to remember when placing a 9-1-1 call from a vTone phone line:

1. As identified above, a VoIP 9-1-1 call is not routed directly to a PSAP. A VoIP 9-1-1 call is first sent to a
call center for screening before it is routed to the correct PSAP.
2. When you dial 9-1-1, you must be prepared to provide your location and callback number to the call
taker.
3. In the event you cannot speak, the call taker may assume you are located at the address you
registered with Vianet. It is important to ensure this information is updated if you move your VoIP phone.
Subscribers can call Vianet to update their address information.
4. Do not hang up unless told to do so, call back if you get disconnected.
5. vTone/PBX service and VoIP 9-1-1 service may not be available in an electrical power outage and will
not be available during a broadband Internet outage.
6. Ensure that you understand the 9-1-1 limitations of your VoIP service and inform all potential users of
your VoIP service of these limitations.
