Call recording at large call centers requires a high-density platform capable of handling a large number of T1 spans in on single server. The industry has been lacking a card capable of supporting a high-density solution.
The connection between PSTN and PBX is forked off to the T116 tapping card using a Sangoma TAP splitter. The connection between PSTN and PBX is passed through, and a high-impedance tap of each signal pair is diverted to the tapping card.
The tapping card demultiplexes and captures 16 TDM spans (eight two-way conversations) and all signalling information be it PRI, SS7, CAS etc. This can then be transferred by software to audio files on a server and entries in a call log database.
A typical call recording application connects the T116 Tapping Board via Sangoma’s WanPipe drivers to a platform such as Asterisk. An application sitting on top of Asterisk logs signalling information to a database, and voice recordings to a file structure on the server.
Apologies, but there are no posts to display.
