CT506 LANforge-FIRE VoIP Call Generator
The CT506 supports SIP and H.323 VOIP call support,
including RTP data-stream generation. If can make 140 calls to itself
(280 VoIP soft phones) per chassis. The CT506 is excellent for testing
whether or not an existing infrastructure can handle increased VoIP call
load, and can also be used to test SIP gateways and other infrastructure.
The CT506 uses the MAC-VLAN feature in the Candela Linux kernel to allow one
virtual interface per phone, so each phone can use a unique IP address and
use standard SIP protocol ports. Normal LANforge FIRE traffic generation
features (Ethernet, UDP, TCP, HTTP, etc) is also supported by the CT506 at no
additional charge.
The CT506 1U rackmount chassis fits into a standard rack and is only 14 inches deep. It supports standard
VGA, Keyboard, and Mouse interfaces for easy console/desktop access to the system.
The rackmount chassis is relatively noisy, so it is better for a data center deployment than
a desktop environment. Other form factors better suited for traveling or desktop use
are also available at similar prices and performance. Multiple LANforge systems can be clustered
together into a single managed realm for increased call capacity.
No additional hardware or software is required, but you may wish to
manage the system using the LANforge-GUI on a separate
machine.

Quick Start Guide
- Connect Management ethernet port to Management network or management PC. If
connecting directly to a PC, an ethernet cross-over cable should be used.
Or, connect VGA, Keyboard, and Mouse to the chassis and manage it locally.
- Connect one traffic generating port to the downstream side of the device
under test. This usually is considered the 'client' side of the network and
will host most of the virtual interfaces.
- Connect second traffic generating port to the upstream side of the device
under test. Virtual interfaces may also be added here in order to emulate
multiple servers.
- Connect power plug to a standard US or European AC power source.
- If managing remotely, install the LANforge-GUI on a separate management PC or Laptop. Windows and
Linux GUIs are supported: Select the correct one from the CDROM or Candela
Technologies Download page and install it.
- The CT506 should now boot. If DHCP is enabled on the Management network,
the CT506 will automatically acquire an IP address. If DHCP is not available,
the IP address will be set to 192.168.1.101 by the LANforge scripts.
- Start the LANforge-GUI on the management PC, or the CT506 server if managing
locally, and click the 'Discover' button.
It should find the CT506 appliance and add the IP address to the drop-down
box in the Connect widget. Press 'Connect' and you will be connected to
the CT506.
- Select the Layer 3, VOIP/RTP, Layer 4 and other LANforge FIRE related
tabs in the GUI to see existing traffic connections and to modify them
or add new ones. You can also view a real-time report of the test with the
'Display' button for some traffic types. Any modifications take place
immediately after you click 'Submit'.

Software Features
LANforge VoIP/RTP Call Generator Feature Highlights.
- SIP and/or H.323 protocol used for call management.
- SIP and H.323 are now supported on both Windows and Linux.
- SIP/UDP supported, H.323 uses both UDP and TCP.
- Can use directed mode, where VoIP phones call directly to
themselves.
- Can also use Gateway mode where the VoIP phones register with a SIP
or H.323 gateway.
- SIP authentication is supported.
- RTP protocol used for streaming media transport, and supports the
following CODECS. More codecs will be supported in the future.
- G.711u: 64 kbps data stream, 50 packets per second (SIP, H.323).
- Speex: 16 kbps data stream, 50 packets per second, www.speex.org (SIP on Linux ONLY).
- G.726-16: 16 kbps data stream, 50 packets per second (SIP ONLY).
- G.726-24: 24 kbps data stream, 50 packets per second (SIP ONLY).
- G.726-32: 32 kbps data stream, 50 packets per second (SIP ONLY).
- G.726-40: 40 kbps data stream, 50 packets per second (SIP ONLY).
- G.729a: 8 kbps data stream, 50 packets per second (SIP ONLY).
- NONE: A messaging-only configuration is now supported (SIP ONLY).
- Supports PESQ automated voice quality testing.
- RTCP protocol used for streaming media statistics (SIP only).
- Each LANforge VoIP/RTP endpoint can play from a wav file and record
to a separate wav file. Almost any sound file can be converted to the
correct wav file format with tools bundled with LANforge. Sample voice
files are included.
- Current benchmarks show support for 280 or more
emulated VoIP phones per high-end machine.
- LANforge VoIP/RTP endpoints can call other LANforge endpoints or third party
SIP or H.323 phones like Cisco and Grandstream. Third party phones can also call
LANforge endpoints and hear the WAV file being played.
