Telephony connectivity

This section relates to the basic telephony interface between your switch (telephone exchange) and Blueworx Voice Response:

Switch type

What type of switch is Blueworx Voice Response going to be connected to?



Software level:

What type of signals does the switch receive?


See Analog interface.

T1 digital?

(Canada, Japan, China (Hong Kong S.A.R.), U.S.A.)

E1 digital?

(Europe, Latin America.)

Voice over Internet (VoIP)


If the signals are digital, what type of signaling protocol is used?

Channel associated signaling?

See Channel associated signaling.

Common channel signaling?

See Common channel signaling.


See Coexistence of signaling protocols.

Channel associated signaling

What channel associated signaling protocols are provided by the switch?

What capabilities are available with these channel associated signaling protocols?

Call transfer?

Answer detect signal?

Far-end hangup signal?

What call information does the switch provide?

Calling number?

Called number or DNIS?

What types of address signaling are supported by the switch?

Decadic dialing (dial pulse)?



How does the switch control address signaling?

Ground start or wink start?

Delay start?

Immediate start?

Dial tone?

How does the switch send the called and calling numbers?

In-band in the information channel?

Out-of-band, in the signaling channel?

Analog interface

If the incoming signals are analog, you need a channel bank to convert them to digital. What protocols are to be used?

To connect the switch to the channel bank?

To connect Blueworx Voice Response to the channel bank?

CTI integration

You need to consider if and how to integrate the voice applications into a wider network.

Is integration with CallPath required?

See Integrating Blueworx Voice Response with Genesys Framework.

Is integration with Cisco Intelligent Contact Management software required?

See Integrating Blueworx Voice Response with Cisco ICM software.

Is integration with Genesys CTI required?

Availability and Redundancy

Are any of the redundancy features to be used in your configuration?

Switch queuing

You need to think about how to integrate the voice applications into your current switch configuration. For more information, see Planning the switch configuration

Does the switch offer queueing?

Is the switch configured with multi-tiered queues?

Will the existing queue configuration work when Blueworx Voice Response is included as an agent?

Power supply

What kind of power supply do you need?


DC (-48v)?
