Our Mission

Innovative, bullet-proof software.
For over 40 years.

Since 1984, Parwan Electronics Corporation (PEC) has been creating innovative, bullet-proof software — from home-based business solutions to high-end IVR and voicemail systems for cellular phone carriers. With more than 40 years of experience, PEC has researched and developed feature-rich, efficient, cost-effective products to suit your telephony and notification requirements.

Integration

One platform. Every protocol.

PEC software products support every voice and data protocol that matters — so you don't have to rip out your existing infrastructure to use our products.

Our voice processing platform supports loop-start, ground-start, DID, T1, E1, Signaling 5 (SS#5), Signaling 7 (SS#7), ISDN, and VoIP SIP interfaces. Voice mail and automated attendant features are fully integrated to operate on any PBX.

The same engineering depth that makes our voice platform reliable also powers USANotify's modern REST API, file-based, HL7 v2, and FHIR R4 integrations — meeting you where your stack is, not where vendor lock-in wants you to be.

Marketing

Designed for small businesses and Fortune 500s alike.

PEC has designed products with the small business owner as well as the corporate market in mind.

For small companies, PEC offers software in 2, 4, or 8 port configurations. In contrast, we've designed and developed software with 24, 32, 64, and 512 ports to meet the needs of large corporations and carriers handling millions of calls per day.

PEC prides itself on the ability to deliver quality products at cost-effective prices. We're a conservative, long-term-thinking company — one of the founders of the voice processing industry — and we approach every customer relationship the same way.

Global distribution

50,000+ ports installed. Six continents.

PEC has installed over 50,000 ports of software worldwide — spanning North America, South America, the Middle East, South Asia, Eastern and Western Europe, and Africa.

Because we support every standard telephone signaling protocol — T1, E1, SS#5, C7/SS7, and VoIP SIP — we've been able to install ports on every continent that has a phone network.

PEC software is designed to run on multiple platforms, from Microsoft Windows server editions to modern 64-bit Linux deployments on AWS and Azure cloud services. Wherever your infrastructure runs, our software runs alongside it.
