Ditech Communications

April 8, 2005


Ditech Communications is a veteran in the telecom space and they have some high-tech solutions to many carrier problems. I spent some time discussing their VoIP solutions and their strategy boils down to making VoIP sound better. They are able to cancel acoustic echo (the noise from the microphone reflection), background noise and hybrid echo (the echo that results from converting 4 lines of voice into two) for example.

They are also very focused on helping carriers with VoIP peering. In the VoIP space, different carriers use different formats to carry their voice packets.

Going Back To NYC

April 7, 2005

I am taking a red eye flight back home and look forward to getting to work. I met with a number of VoIP companies and they all seem to be doing well. I heard that Q1 was a bit slow in the enterprise VoIP space for some reason but there are a record number of deals on the table for many companies. In all I saw companies selling to OEMs, enterprise customers and service providers.

Bubb Leaves Intel

April 6, 2005

An industry Icon, Howard Bubb is stepping down from Intel. Bubb was the head of Dialogic during the roaring days of computer telephony/CTI where the market grew at an astronomical rate. Those of you at industry events remember Bubb speaking at events hosted by the likes of Harry Newton... In fact there was even a Howard Bubb show at suc events.

Dialogic was a leader in DSP resource boards and although Natural Microsystems really discovered the VoIP gateway market before Dialogic, Bubb's company powered back to lead the space and soon thereafter sold to Intel.

Many in the industry complained that Dialogic which sold for under a billion dollars to Intel was undervalued.

Airline Morale

April 5, 2005

Yesterday's USA today (April 4, 2005) has a letter to the editor from Patrick Lee titled Airline passengers get far more than they're paying for. The letter talks about how the price of an airline ticket for spring break is the same as it was 25 years ago and that is not even after adjusting for inflation!

The letter was in response to another letter title "Airlines once paid close attention to customer service," and it points out that most passengers pay more for parking than they do for airline tickets these days. According to Lee, most of the airline company employees have taken pay cuts so that jet service remains cheap. Furthermore, terminals have been upgraded at no charge to customers.

I have been writing about airlines for over half a decade (mostly complaining) and this letter addresses part of what is going on.
