Advanced Diagnostics

A key component driving the success of our digital telephony cards is the Wanpipe device driver. Not only does it function as a robust device driver, but also offers a suite of diagnostic functionality, such as on-board PCAP line tracing (signaling and RTP), line statistics and even audio tracing! The Wanpipe driver can also improve your Asterisk system performance by 70%, which means more simultaneous calls and increased ROI!
