[Freeswitch-users] ASR using mod_unimrcp, vlingo

Hi All Has anyone had any experience doing ASR with mod_unimrcp in javascript? In particular, how do you deal with grammars? A simple piece of demo code would be massively appreciated - the documentation on mod_unimrcp ASR javascript bindings is TBD, which I assume means 'to be documented' ... unless it means 'to be developed' ... Also is anyone aware of a vlingo integration for freeswitch? All the best Jim
