I have put the calltest.js in /usr/local/freeswitch/scripts and changed sofia to openzap/default/1001@192.168.1.2 in the coding and i got the error:

Error:

2008-09-22 10:13:26 [ERR] switch_ivr_originate.c:926 switch_ivr_originate() Cannot create outgoing channel of type [openzap] cause: [CHAN_NOT_IMPLEMENTED]

2008-09-22 10:13:26 [ERR] inline:1 mod_spidermonkey()  You must call the session.originate method before calling this method!

so i have changed that to sofia again.

As Anthony Minessale said, i have changed @ symbol to %  like sofia/default/1001%192.168.1.2 in the coding.But i am getting the following error:

Error:
