Overview
The GSM Series cards are PCI/PCIe base cards. The GSM Series cards are
designed to handle the GSM calls with Asterisk. These are the Gateway card
which will interface with GSM based PSTN network with the Asterisk based IP
network.
VoIP communication needs the capability to mediate between endpoints
supporting different Networks, but this requires Gateway functionality.
Asterisk, is capable of terminate the some type of calls with other calls, such
as terminating the SIP based IP calls with H323 based calls. But it is lacking
the call terminating capability with the PSTN/GSM network.
This GSM card will add Gateway capability and provides excellent voice
quality, without affecting latency or using up precious host CPU resources.
The GSM card comes with bundled software to make the product architecture
independent.
The GSM Series cards are capable of handling up to 4 bi-directional GSM
terminating calls. All calls are fully indemnified no additional licensing is
required for their use.
