Chan_misdn is an Asterisk channel driver which enables the utilization of supported ISDN BRI/PRI devices through the open source PBX software.
One of the standout features of chan_misdn is its support for a variety of connection modes, including NT and TE mode, as well as PP and PMP mode. It also supports both BRI and PRI (with BNE1 and BN2E1 Cards), making it incredibly versatile for different use cases.
Another key feature of chan_misdn is its DTMF detection in HW+mISDNdsp, which is significantly better than Asterisk's internal capabilities. The software also allows users to display messages to phones that support display msg and enables functionality such as HOLD/RETRIEVE/TRANSFER on ISDN phones. Users can also choose to screen or not screen user numbers, depending on their preference.
To further enhance audio quality, chan_misdn includes basic echo cancellation and volume control. Security is also a top priority, with the software offering crypting with mISDNdsp (Blowfish) and data (HDLC) callthrough.
This latest release of chan_misdn has seen improvements in release management, making it the first stable version of the software. Overall, this is a great option for anyone looking for a powerful and reliable channel driver for their Asterisk PBX.
