Sangoma Technologies Launches Four-Port A104 T1/E1/J1 
Voice/Data Card: Advanced Flexible Telecommunication 
Card Joins FPGA Family

TORONTO, ONTARIO--(CCNMatthews - Dec. 6, 2004) - Sangoma Technologies 
Corporation (TSX VENTURE:STC) (www.sangoma.com), a leading provider of 
connectivity hardware and software products for WANs and Internet 
infrastructure, has launched its four-port A104 AFT (Advanced Flexible 
Telecommunication) T1/E1/J1 voice/data card.

Capable of handling both voice and data, the A104 is the latest addition 
to Sangoma's family of cards that currently includes the A101 
single-port and A102 dual-port cards.

Like the A101 and A102 cards, the A104 has a 2U form factor (120mm x 55 
mm, 4.7" x 2.2"). This 3.3v/5v PCI card supports bus-mastering, 
ring-buffer DMA architecture and fully shared interrupts, making it 
ideal for demanding environments such as the Asterisk(TM) Open Source 
PBX/IVR project.

The A104 supports full channelization of up to 124 individual DS0 
timeslots, making it ideal for multi-channel data hub implementations 
and integration with PC-based VoIP PBX systems that can take advantage 
of this capability. Field upgradeable hardware programming allows for 
new functions to be added as they become available, as well as providing 
the capabilities for hardware-based ATM and SS7 MTP2 support.

"The A104 allows us to define a new price/performance standard that is 
unparalleled," says Sangoma Technologies President and CEO David 
Mandelstam. "We see the A104 with its 2U form factor being particularly 
suited to use in large hub servers and the soft PBX market."

Sangoma Technologies' current solution set includes:

/T/

- WANPIPE(R) internal media gateways, transporting TDM voice, IP data 
  and video over T3/E3, T1/E1/J1, ADSL and serial links
- High performance and reliable communications modules for OEM 
  projects involving ATM, Frame Relay, X.25, SS7, HDLC, BiSync 
  and other protocols
- The WAN Edukit(TM) protocol teaching tool for educational 
  institutions
- POS (Point-of-Sale) interface cards for security and customer 
  loyalty applications
