PowerPC VoIP appliance comes with Linux cross-tools

Jun 6, 2008 — by Eric Brown — from the LinuxDevices Archive

Pika Technologies is shipping an IP-PBX appliance with a cross-compiling SDK (software development kit) based on Denx Linux and the open source Asterisk PBX software stack. “Pika Warp, the Appliance for Linux” supports 32 simultaneous calls, and provides music-on-hold and power failure transfer, the… vendor claims.

Announced last Fall, the Appliance for Linux is now shipping. Pika says developers can use the platform to create low-power, low-cost solutions for small businesses. Compared to PC-based, “data centric” competitors, the Appliance covers more of the traditional features users expect, Pika says, citing music-on-hold (MOH) and failover to analog operation (via RJ-11 ports build into the optional FXS modules) in case of power failure. Other touted features include integrated voice response (IVR), predictive dialing, appointment reminders, and paging, says the company.

  • Operating temperature — 0 to 104 degrees F (0 to 40 degrees C)
  • Operating system — Denx ELDK, with a 2.6.19.2 Linux kernel

The PADS development environment

The Appliance's Linux implementation was built atop Denx's Embedded Linux Development Kit (ELDK). The system ships with a “Pika Application Development Suite” (PADS), described as a host media processing (HMP) software framework that enables developers to create telecom applications, including IVR, voicemail, custom PBX systems, and gateways. PADS reported includes Pika voice processing applications for tone detection and generation, play/record, VoIP, echo cancellation, and conferencing. The framework also includes a cross-compiling toolchain, linker, and debugger, as depicted below.

PADS also ships with Pika's MonteCarlo SDK (software development kit), which includes the Denx ELDK distribution, drivers, and related tools. The MonteCarlo SDK offers a choice between low- (HMP) and high-level (GrandPrix) C-based APIs. The PADS package includes SSH access and Asterisk, along with a database, web server, web language, and other tools.

Competitors in the open-source IP/PBX telephony market include 4S Newcom's Mac-based Blue4S and Digium's Asterisk Appliance (shown at right). Digium was founded by Asterisk originator Mark Spencer. Packt Publishing recently published a book on Asterisk by Nir Simionovich called AsteriskNOW, and has provided a sample chapter for download.

Stated Terry Atwood, Pika's VP of sales, “The one thing that sets Pika's Appliance apart is PADS. Through PADS, Asterisk and Linux developers are able to easily take the unique, value added features and applications they have developed, modify them for the appliance embedded environment, and compile a complete package to load on the box.”

Availability

The Pika Warp Appliance for Linux is shipping now at a price between $600 and $1,500, depending on configuration and volume, says Ottawa, Canada-based Pika Technologies. More information on the appliance may be found here.
