[Freeswitch-users] How to originate gtalk calls

Hi Guys, I've configured a gtalk client based on the steps in this url: http://chesterton.id.au/blog/2007/12/31/freeswitch-and-google-talk/. But i'm not sure how to originate calls to different gtalk users dynamically. I've tried this: freeswitch> *originate dingaling/gmail.com/userAAA@gmail.com &echo* but got CHAN_NOT_IMPLEMENTED error. *2009-06-23 10:11:01.25414 [ERR] switch_ivr_originate.c:1495 Cannot create outgoing channel of type [dingaling] cause: [CHAN_NOT_IMPLEMENTED]* Please kindly let me know what the correct originate string is. Thanks!
