publicVoiceXML Hardware abstraction with VoIP-CAPI / XCAPI

We have made first successful and promising tests both with VoIP-CAPI(ikon) and XCAPI(TE-Systems) in combination with publicVoiceXML2.6.1. VoIP-CAPI and XCAPI behave like virtual ISDN cards that enables publicVoiceXML to communicate via H323.

With VoIP-CAPI or XCAPI.....
.... publicVoiceXML is Hardware independent
.... publicVoiceXML has better scalability (e.g 5/13/42 lines)

Unfortunately VoIP-CAPI and XCAPI ...
... only works on windows at the moment. Both companies(ikon, TE-Systems) told me they have plans to release a Linux version.
... in combination with publicVoiceXML isnt fully tested yet... read more
