In case you access to the IVR project design and you can't see the structure and blocks that you created, please follow these tips to recover it.
The IVR projects are stored in the table "projects" of the xcally DB.
The IVR design is saved into 2 fields:
schema (last saved ivr schema)
schema_run (current running IVR schema)
You will probably see the field "schema" empty and the field "schema_run" with your running IVR data.
In order to do the recovery, just copy and paste the field "schema_run" to "schema" and your IVR script will back to web interface.
