PacketGen™ Application

PacketGen™ is a PC-based real-time VoIP bulk call generator (including both SIP signaling and RTP generation) for stress testing and precise analysis of the VoIP network equipment.

4

Applications

 Manual and Bulk Call generation

• Supports SIP, RTP, RTCP, with full SIP Functionality - Call Forwarding, Call Hold, Call Transfer, etc
• Various traffic generation capabilities – voice, tones, digits, and more
• Up to 2000 concurrent calls with full duplex RTP per i7 PC running single SIP/RTP Software Core;
• Distributed architecture allows achieving higher call density by interconnecting more number of systems with SIP and RTP software cores
• Multiple probes with single GUI at central site
• Generate test calls to IP Phone, ATA, PSTN, Wi-Fi, Cellular
• Software defined architecture

 Stress Testing

• Generate 200 Bi-direction RTP streams per SIP-RTP pair (Stackable)

 Load router DSPs, Load network pipe

• Generate SIP call traffic – 250 INVITES per sec

 Find gateway access limitations

• Generate proxy registration load

5

• Voice Quality

▪ Automatically and manually play/record test voice files in a synchronous manner ▪ Automatically transfer degraded voice files to GL VQT analysis, providing ITU-standard MOS (PESQ, PESQ WB, PAMS, & PSQM) ▪ Results rated as excellent, good, fair, poor

• Regression and Acceptance Testing –
• CLI allows users to create traffic using their own test software
• Can be used for OEM testing
• Field acceptance test, Traffic generation
• Matrix Testing –
• Distributed network call agent to agent over customer networks
• One-Way transmission – send bi-directional traffic to verify continuity. Enhanced capability with action scripting
• Service level agreement verification
• Others - Protocol Compliance, Codec Compatibility, & Voiceband Testing

Capacity

• Distributed architecture for SIP and RTP systems provide high call rates and media streams.
• Provides high density performance; PacketGen™ can generate 2000 simultaneous calls on an

core i7 PC. Higher density is also achievable using multiple systems

• Up to 20 SipCores can be run on the same PC or on multiple PC systems. All 20 SipCores can

be remotely controlled from a single system. Call Generation

• Full SIP Functionality - Registration, Call Forwarding, Call Hold, Call Transfer, Authentication,
• Manual and Bulk Calling capabilities with complete flexibility on each call session
• RFC 3261 compliant, RFC 2833 digit generation/detection
• Generates both SIP signaling & RTP traffic (voice, fax, digits, tones)
• Supports run-time parameters to control call and traffic behavior – SIP Call Parameters and

Digit Generation and Detection parameters (power, on/off, pause, and amplitude).

process through scripts

• Monitoring IVR System for voice and data quality
• Send/Record voice files on any (or all) RTP sessions.
• Perform various actions like send / detect digits / tones (both Inband and Outband), talk

and playback actions on any (or all) RTP sessions to simulate real world traffic

• Allows user to create early media scenario

Auto Traffic & Signaling Actions

• Auto-Action feature provides a quick and easy method to configure signaling as well as traffic actions, once the call

session is established

• RTP Traffic options include transmit / record voice, generate / detect tones, digits and noise and send / receive fax
• Supports generation of impairments on outgoing RTP streams – Latency, Packet Loss, Packet Effects

• Send Actions – Send GL Propriety voice files, DTMF or MF Digits (In-band or Out-Band), user-defined single/ dual frequency

tones, real-time voice from default audio device (microphone).

• Loop Back – Loopback real-time voice traffic from the received RTP/RTCP to the send RTP/RTCP (all received traffic will be re-

generated as send traffic).

• Receive Actions - Record received voice file in GL Propriety file format, detect incoming single/dual frequency tones and

DTMF/MF digits from in-band received voice; Play received voice to default audio device (speaker).
