GL Communications Inc., announced today the release of enhancements to PacketScan? software - a real-time IP and VoIP analyzer. Speaking to the mediamen, Mr. Vijay Kulkarni, CEO of the company said, ?GL's PacketScan? is a real-time IP and VoIP analyzer that non-intrusively analyzes and captures live IP traffic, and segregates them into SIP / H323 / Megaco / MGCP calls. It also collects statistics, CDRs, detailed protocol traces, ladder diagrams, and a host of other useful information about VoIP calls?. He added, ?Applications include monitoring of IP phones, Gateways, IP Routers, Switches, and Proxies. Its real-time nature makes it an outstanding tool for live monitoring of VoIP traffic as well as long-term traffic statistics gathering?.
Mr.Kulkarni, further added, ?PacketScan? can also monitor, report, analyze, and capture calls for infinite time, limited only by the finite space of your hard disk or network hard drive!?.
Summary of the New Features
?Performance
PacketScan? breaks ground with high density performance. It can now handle up to 1300 simultaneous calls with bi-directional RTP traffic.
?MEGACO Calls Summary
MEGACO is a media gateway control protocol, which is used between Media Gateway and Media Gateway Controller (Call Agent). Megaco/H.248 uses a series of commands to manipulate terminations and contexts using events, signals and other descriptors. PacketScan? has been enhanced to provide a summary of MEGACO calls. Calls are classified as active, completed, or failed.
Summary of each call contains signaling information such as Physical Termination, Ephemeral Termination, Context ID, Call Start Time, Call Duration and information about media sessions associated with it. Media sessions provide detailed information such as codec used, MoS and R-Factor scores, jitter, delay, total number of packets received, missing, duplicate and out of order packets counts and percentage.
?Call Graph
Ladder diagrams display protocol message sequences. They also display the decoded information of the selected message as shown in the above diagram.
?MEGACO Statistics
MEGACO Statistics provides all possible statistics about MEGACO calls in the network such as total, active, completed and failed calls. It also provides the total number of MEGACO Add, Modify, Subtract, AuditValue, and Audit Capability message counters. These counters are updated in real time.
?Registration Summary
In PDA Summary View the user can see a detail summary for all registration request (SIP) attempts. Each registration summary contains information such as User Agent being registered, Registrar Address, current status of the registration, registered time, registered duration, expiry time and remaining time. The below diagram provides the details of registration summary.
?Registration Graph
Displays ladder diagram for the selected registration attempt. It also displays the decoded information for the selected SIP message on the ladder diagram as shown in the above diagram.
?Registration Statistics
The registration information includes counters for total, active, completed and failed registration attempts. And also counters for total registration and de-registration frames.
?Active Registration Graph
This graph displays the total number of active registrations over a period of time.
?Triggers and Actions
In Triggers and Actions, there is addition to the list of call parameters to add more feasibility to filter the calls. Some of them are: Session Request Delay, Session Disconnect Delay, SIP Error Codes and more.
Other Features Include:
?Monitor progress of up to 1300 simultaneous calls with bidirectional RTP traffic
?Supported protocols - SIP (SIP Session Initiation Protocol RFC 2543 and RFC 3261), Megaco RFC 3525, Megaco RFC 3015, MGCP, H323/H225, and RTP
?Supports decoding of MAC, IP, SIP, UDP, TCP, RTP, RTCP, T.38 (Fax over IP), and SMPP
?Call capturing based on call agents or triggered actions such as MOS, R-factor, jitter, packet loss, duplicate packets, or called / calling numbers (SIP/H323)
?Full RTP Analysis with audio capture/playback supported for all common codecs

About GL Communications Inc.
Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.
GL?s TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, STM-1, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, etc.), and with capacities up to thousands of channels.
GL?s VoIP and IP products generate / analyze thousands of calls / traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. Additional features include visual analysis, real-time listening, and recording. The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.
GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL's VQT provides a widely excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless, and Landline) are all available.
GL?s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.
GL?s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including compliance testing per G.168 and G.160 across TDM, IP, VoIP and Wireless networks. GL?s wirelss VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and other distortions are easily assessed and accurately measured.
GL?s Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.
GL?s Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
