Telephony hardware and protocols

To transmit and receive voice signals to and from the telephone network, Blueworx Voice Response can use specialized hardware: pSeries computer digital trunk adapters. Digital trunk adapters are installed in the pSeries computer system unit. For more information, see What connects to what?.

Blueworx Voice Response can work with a variety of telephone switches, using channel-associated signaling or common-channel signaling protocols to carry the voice traffic and control calls. With some channel-associated signaling protocols, an exchange data link may be required to provide functions such as far-end hang up detection, provision of call information, call transfer, and message waiting indication.

No hardware adapters are required with BladeCenter or pSeries computers when using the DTNA software support for Voice over IP networks.
