|Xtend IVR - FAQ
comprises of the development environment and the runtime
capable of supporting the licensed number of ports. The
standard edition is used for development and final production
implementations of IVR solutions. The standard edition runtime allows
complete customisability of the About box information and the main
window bitmap as per user requirements. Standard Edition is priced and
licensing is enforced via a USB dongle.
Developer Edition comprises of the development environment and a single port runtime. The developer edition is used to develop and demo an IVR solution using Xtend IVR. However, the developer edition runtime should not be used in final production implementations of IVR solutions. The runtime is full-fledged, supporting one telephone line and is not technically limited in anyway. However restrictions on customising the About box information and the main window bitmap are present. Developer Edition is available as a free download.
When you install the Xtend IVR toolkit (Standard or Developer) it will
add desktop icons named "Xtend IVR 3.0" and "Xtend IVR 3.0
Developer Edition". You can run the Xtend IVR
runtime or the Xtend IVR Developer Edition by double clicking on the
appropriate desktop icon.
You usually get
this error message if you try to run the Standard Edition Xtend IVR
runtime without plugging in the USB dongle. By default, when you install
Xtend IVR Standard Edition, the drivers for the dongle are
automatically installed. In case you have re-installed the
Operating System, please re-install the Xtend IVR Standard Edition also.
Xtend IVR has a maximum supported limit of 512 phone
lines on a single machine. This is an artificial
limit imposed primarily for ease of testing the database support,
language stability and the load factor. This limit will be
increased in the future. If more than 512 phone lines are required to
be supported, it is recommended that multiple machines be used.
supports any telephony compatible Text-to-Speech Engine that supports
the Speech API (SAPI 4.x & 5.x) and provides a 16 bit, 8 KHz
waveform output. Xtend IVR has been tested with the Microsoft TTS
Engines as well as with the TTS Engines available from Lernout
& Hauspie (L&H).
Windows 2000, XP and 2003 are the supported platforms. Xtend IVR will work under
Windows 98 & Me with reduced functionality.
available that support Digital (E1/T1), SS7, H323 & SIP and
Analog voice devices from Eicon, Dialogic and Ai-Logix. Drivers for
TAPI, Opal H323/SIP and Skype are also available. Additional voice
devices are being supported on an on-going basis, depending on customer
requests and device availability.
Xtend IVR 3.0 is the latest version of Xtend IVR.
All Speech API 5.x engines are supported for Speech
Recognition. The ability to dynamically create and load multiple
recognition grammars is supported as is the ability to perform speech
cut-through on complete recognition of sentence, on recognition of the
first word and in presence of speech.
Xtend IVR accomplishes tone and pulse detection via the telephony voice
device API. If the voice device supports this capability, then Xtend IVR will support it.
Note: Voice Modems do not support pulse detection capability.
Xtend IVR supports both analog and digital lines. For digital lines you need a
voice card that supports the specific protocol provided in the E1/T1
connection. Note: All
digital protocols may not be supported by all voice cards.
access is supported via the DB plugin which supports ADO or ODBC. Full-fledged examples are provided in the Developer Edition that illustrate
how to achieve this.
If the hardware is half-duplex, then Xtend IVR will not be able to simultaneously play
or record wave files. For example, the D/4 PCI UF card from Dialogic is a
half-duplex card. In most cases, Xtend IVR automatically
determines if the voice card is full-duplex or not and will function
Xtend IVR includes a development environment that utilises the sound card to
simulate a voice device. This enables the developer to create and test
an IVR using a multimedia capable PC. The runtime does not require the
8 KHz, 16 bit, mono.
