VXML: New Apps From Old

What opportunities does the ASP model offer developers? Traditional CTI development tools make things easier and more open. Will large-scale implementation of the ASP model reverse this trend? Will telecom developers have to commit themselves to proprietary platforms just to gain facility with
their languages, APIs, and other idiosyncrasies?

In search of answers, I spoke with Ian Widger, president and CEO of AccessLine Communications, a hosted communications provider targeting large enterprises and carriers. AccessLine has deployed with PeopleSoft and the Chicago Mercantile Exchange, but I was more interested in the opportunities for third parties looking to customize AccessLine's offerings for their own markets.

The response was encouraging. First, if AccessLine's off-the-shelf offering doesn't suit customers' needs, AccessLine can modify it for them or hand over limited control to the customer directly through a service creation environment (SCE). The SCE has several levels; there is an Individual Level, which allows personalization without exposing key functions to (uneducated) tinkering. The Administrator Level comes next, followed by the Supervisor Level. Finally, there is the Product Creation Level, usually given to carriers who want to make significant changes -- for instance, to focus on the needs of a certain vertical market.

But options for customization go beyond this. "Web developers are the telecom developers of the future," predicted Ian Widger, and therein lies the potential. VXML and its offshoots are bringing us to the point where, as Ian quipped, developers will ask "How do you want your Web site? Now, how do you want your communications?"

Hard to believe? No. Already AccessLine and others have telecom app libraries providing basic building blocks. You need voice mail? Just pull the app off the shelf, manipulate it with VXML, publish it to a server, and you're in business.

What about testing? Security? How do you know that your services won't be affected by another developer's tweaking? With AccessLine, partitions prevent a third party from damaging another party's apps. And many hosted providers offer hosted testing environments too.

For anyone feeling nervous about Web developers handling voice -- after all, how often does your Web server go down? -- Ian made some good points. First, these developers won't be handling traditional telecom so much as enhanced features: integration of telecom with e-commerce platforms, for example. And secondly, many users already view the Web as a "god-given right." Web developers are faced with increasingly rigorous expectations, and this trend will continue.

Right now working with a hosted communications provider like AccessLine requires product-specific training, but the day isn't far off when standards don't only apply to comm servers or VoIP, but to SCEs as well. Ian suggested that the market will eventually force companies like AccessLine to support VXML and its progeny. In fact, Ian said that AccessLine plans to have extended VXML support available in Q1 2001.

RadiSys, LynuxWorks To Develop Open Architecture HA Linux
RadiSys Corp. and LynuxWorks announced plans to develop an Open Architecture High-Availability Linux system targeted for telecom and embedded system applications which require "five-nines" or better availability. Implemented as an enhancement to LynuxWorks' BlueCat Linux and the Linux-compatible LynxOS real-time OS, the new OS extensions will provide full support for CompactPCI hot swap operations, allowing online repair of standard peripheral controllers as well as completely dynamic system reconfiguration. The OS will also support failover between redundant system host processors in a CompactPCI system and advanced platform management through the Intelligent Platform Management Interface (IPMI). In contrast to other high-availability operating systems tailored to use platform-specific capabilities of a particular manufacturer's systems, RadiSys and LynuxWorks will produce software which functions completely through open, standard interfaces. The key specification that makes this possible is IPMI, which has been adopted as the standard platform management interface for CompactPCI systems.
