Is it really possible to replace
an office PBX with this service?
Yes, mobile PBX and mobile voip has been
available for a long time via WiFi and now
that 3G voip 4G voip is available the service
can be delivered outside of WiFi range. All
of the PBX features are the same as an office
PBX but instead of a large handset attached
to an office network it uses a wireless mobile
connection.
How does network selection / handoff
work?
The phone can be configured to favour GSM
or Voip2Air. When either one isn't available
the other will take over automatically. So
if there is no GSM or 3/4G at your house but
you have WiFi, the phone will use that for
calls. The priority can be set for minimum
cost.
What is the mobile voip call quality
like?
Voip2Air has designed the mobile voip infrastructure
specifically to maximise call quality. This
includes using uncompressed voice, a low latency
network, high quality Cisco network components
and constant monitoring. You can always try
it before you buy using our free trial to
satisfy yourself.
How much does it cost?
Pricing is based on a cost per person per
month this includes all features and technical
support. Call charges are billed separately.
There are no other costs.
Which phones does it work with?
Voip2Air currently supports all Windows Mobile
6 onwards devices (e.g. HTC, ASUS, HP, Samsung)
and all Nokia
E series and some N series phones. In
most circumstances any SIP client on a mobile
is supported.
How does provisioning work?
First the phone needs a SIP configuration
file which we send using SMS to your phone
(so a PC isn't needed). There are some instructions
on our web site or our technical support team
can talk you through this. Secondly the phone
needs to register using a wireless network.
When registered you are ready to make and
take calls. The whole process takes 2-3 minutes
per phone.
How am I billed for the service?
Billing is done every month the fee is billed
in advance, the calls in arrears. We can also
provide a pay as you go service as well. All
calls are accessible via the on line portal.
What levels of failover and resilience
are there?
There is no single point of failure in terms
of data centre, softswitch servers, internet
pipe, PSTN trunks, network components. If
there was a problem with your 3G or broadband
circuit we can route to your mobile phone
using the GSM network. We can even route calls
to a SIP hand set or PC softphone if you mobile
develops a fault.
