In case chan_capi is used to terminate or initiate the fax transmission all necessary features are provided by Diva softIP. softIP exposes one CAPI interface towards
chan_capi and SIP interface towards IP network.
This is no need to change chan_capi configuration. This is only necessary to specify softIP as CAPI controller. All other configuration details are handled by Diva softIP configuration.

Diva softIP allows to preserve all voice features. This is possible to process voice calls over IP and switch between voise and fax media. Diva softIP can be used
in one system with Diva hardware and supports line interconnect (conferencing) between processed by Diva hardware and by softIP voice streams.

In case softIP is used with one or more Diva boards in resource board mode then V.34 Clear Channel Fax and G.729, iLBC, G.726, G.723, GSM and other vocoders receive available for chan_capi.
