The VoIP-2 Card is an outstanding new product
6
that allows AudiaFLEX to leverage the power and
exibility of VoIP telephone systems for distance
conferencing over audio systems. Of course, as
with any new product, there are going to be a few
questions. Following are the most frequently asked
of those questions, along with the answers your
customers are looking for.
Is it correct to say the VoIP-2
Card acts as an end-point?
Yes, the VoIP-2 Card basically acts as any other VoIP
phone on the network would. The main feature Biamp
AudiaFLEX adds is the ability to route the VoIP call into
an audio system for conferencing.
We are moving from an old Cisco
CallManager to a SIP-based system,
will the VoIP-2 Card work with both?
The VoIP-2 Card ONLY functions with SIP, so the new
system being used will be ne. However, if the old
system can make use of SIP, you will be able to use
both systems.
Do we need PoE switches?
The VoIP-2 Card does not require a PoE switch
to operate, although using a PoE switch will not
damage the card.
Can we set any of the congurations
from a call manager?
The VoIP-2 Card generically interacts with many SIP-
based systems, so all congurations are set via Audia®
software rather than any other third party interface.
Which call managers
will it work with?
The VoIP-2 Card is designed to work with SIP-based
proxy servers.
What Codecs are available?
Currently the available Codecs are:
• G.722 (Default Priority Setting)
• G.711u (u-law)
• G.711A (A-law)
• G.729AB
• G.723.1
How does it determine the priority
of the Codecs? Can it be set to
accept a lesser Codec? Can we
add/remove Codecs?
Codec priority is set to default as the top to bottom
order shown above, with the top being the highest level.
The priority level of the Codecs can be set up per line
in Audia software by moving Codecs up or down in the
Codes list. Additionally, Codecs may be turned on or off
by setting the check boxes located next to the available
Codecs in the list and resending the AudiaFLEX
conguration. Proxy servers can also be set to disallow
certain Codecs.
How do we dene the extension
number/subscriber number?
Once an extension number has been established by
your IT Department, it is simply entered into the Audia
Software then loaded to the VoIP-2 Card. Biamp has
made an advanced settings form available to your
IT Department to provide essential information
to the Audia programmer.
Can we see the MAC
Address anywhere?
Once a le has been loaded into the AudiaFLEX,
the MAC Address is available in the status eld
of the advanced VoIP settings.

DHCP? Can we set a static
IP if needed?
The VoIP-2 Card default is to obtain network settings
via DHCP. If this is not desired, the IP information can
be set statically within the network settings page
of the VoIP console control dialog in Audia® software.
Does the VoIP-2 Card support IPv6?
The VoIP-2 Card does not support IPv6 at this time.
Is each line considered a
separate instance with its own
IP and extension?
The VoIP-2 Card can handle 2 lines per card, with up
to 6 cards per AudiaFLEX system. Every line within
the system needs to have its own extension and every
card within the system needs to have its own IP address.
Can we set the lines to
use different Codecs?
You can set the Codec list and priority per line, and
multiple lines can have different Codec lists and
priorities at any given time.
Will the CISCO settings
confuse the cards?
Cisco, or any other third party device manufacturer, has
no control of the VoIP-2 Cards. Therefore the settings
will have no bearing on VoIP-2 Card performance.
How do we dial?
Dialing is achieved via Audia software, although there
are several different ways that an end-user can access
a dialing device. Biamp has a software program called
daVinciTM that can be used to control a softphone VoIP
dialer, as well as many other aspects of the conference
audio system. The system can also be dialed using ASCII
characters via RS-232 or TELNET delivered by third
party devices such as AMX or Crestron.
Can the two ports be bridged
for a conference?
The AudiaFLEX can act as a bridge for all of the lines
that are being delivered to the unit (up to 12). Although
each of these lines must rst register with the proxy
server then either be called or call out to an outside
line, it should be noted that the actual bridging of
these lines is done within Audia software via signal
mixing and routing.
Can the ports be assigned different
QoS (Quality of Service) levels?
For the most part, the VoIP-2 Card can handle different
QoS settings per line, including the RTP and Call Control
settings. There are, however, some QoS settings that
are global per card. Reference the VoIP-2 Advanced
Network Settings sheet for more information
Can we VLAN the lines? Can they
be on different VLANS?
VLANs can be enabled on the VoIP lines although only
a single VLAN can be used per card.

Can the cards be set to
auto answer?
The VoIP-2 Card can be set to immediately answer
an incoming call or answer from 1 to 5 rings.
This feature can also be turned off.
If we decide to change systems,
can we do a mass update on the
cards, for example to change the
priority of the Codecs?
No. If the system is updated, the VoIP-2 interface
must be recongured on a per card basis.
