Hello, I am trying to change the code in mod_callcenter. I want to implement queue add functionality in the code currently it is not available. i followed this link http://jira.freeswitch.org/browse/FS-3338 to add a patch in the mod_callcenter.c file and add the queue also in the database. I have some questions while following the code. Please correct me if my understanding is wrong. 1. There is no database table for queue that is created in the xml and after applying the patch also. after following the code i got that it is stored in the hashtable. So why i can not see in the database and why it is storing in the hashtable.? How mod_Callcenter storing queue information in the freeswitch. 2. Is there any other way to add queue at runtime.?? 3. what is stored in the members table? Please help me out.
