CHAN_CAPI configuration
The Dialogic
®
Diva
®
System Release is compatible with the chan_capi Asterisk interfaces. The chan_capi is a
specific use case to provide CAPI-based ISDN hardware support. It establishes the connection between the PBX
software and ISDN hardware, which provides a CAPI 2.0 compatible interface.
The chan_capi configuration generates a capi.conf Asterisk configuration file and modifies the modules.conf and
makes the available options visible. You need to write your own extension.conf. Consult the examples in the
internet for reference. For Diva-specific commands, see the README, README.media, README.Diva.fax, and
README.Diva.qsig files.
Notes:
• If a new capi.conf is generated, the old version is saved as capi.conf.saved_by_diva.
• The DTMF parameters are set to 80ms Tone/Gap Duration and are detected by the DSP if the capi.conf
is configured via the WEB configuration interface.
• MF and other tones can be detected. See the readme.media file for more information.
• If you use Asterisk 1.6, do not activate RTP support.
