This document provides an introduction and overview of a company that produces IP communications products based in South Africa. It discusses the company's evolution from Phase 1 producing Asterisk telephony peripherals called Comma iTA to Phase 2 producing all-in-one Asterisk appliances called Comma X. It describes the key features and functionality of the Comma X appliances including routing, gateway, PBX, provisioning applications, operator panels, call center analytics, and voice logging. The document also discusses the company's vision, brand, customers, partnerships, and open interfaces.

7. Evolution of mature, open
source products
Phase 1: since 2008
“Generic” Asterisk telephony peripheral

8. Phase 1: Comma iTA
● Vision: Build a robust and scalable alternative to PCI and USB
based telco cards for Asterisk
● Where:
● Comma = “ , ” as word play on “*” and “Comms”
● iTA = Intelligent Telephony Adapter

9. Comma iTA Architecture
● 32-bit softcore µP with dedicated hardware EC, implemented in
an FPGA
● Native Asterisk TDMSpan protocol: Ethernet based “TDM over
Packet” using DAHDI
● Utilities on host machine: Auto-detect and Boot iTA
Benefits:
● Scalable, distributed architectures
● Abstracted from hardware
Case history:
● Vodacom Gated Services (now Smart Village)
