We see from your search that you're looking for information on the term "DTMF",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Firmware cuts voice processing costs from
Zarlink Semiconductor, which we summarised at the time by saying "Zarlink's integrated voice processing firmware provides designers with a 30-40% cost-saving compared to using discrete DTMF and caller ID chips".
A few weeks before,
we featured the news release Canceller copes with complex echo issues from
Zarlink Semiconductor: "Echo canceller combines hardware and firmware to provide superior voice performance across converging networks".
In July 2007, we covered the news from Pika Technologies
concerning its Network interface boards
- take a look at Network interface boards switch to PCIe
which says: "Pika Technologies has brought out PCI Express versions of two of its network interface boards and has added new features to its host-based processing platform".
Take a look also at the news release from Ikanos Communications, Fibre optic company moves into residential market,
as well as Media processing platform brings VoIP to SMEs from Aculab,
and Codec and signalling chipset for telecomms from CML Microcircuits.
