Technical support is available by phone once you are assigned to a specific service person in technical support handling your incident.
You can initiate contact to technical support via a valid S-User account and by opening an incident on http://support.sap.com/ underneath the component BC-SYB-SQA (for SQL Anywhere / MobiLink / SQL Remote / UltraLite issues). When you open an incident on the portal, you can also simultaneously request an immediate callback (or you will be automatically called back for "Very High / P1" issues) and you will be called back once your incident has been picked up by SQL Anywhere support.
