Call routing setup
No special routing setup required for the application to work. But special configuration may be created for the SER to prevent recording CDRs for the calls generated by the application.

Database usage
The application uses IVR Prompts facility for the Welcome Call message storage.
Setting a custom prompt
It is possible to play a custom greeting to the user from the Welcome Call application. The first step is to create an IVR prompt:
$ /home/ssp/scripts/ivr_prompt_utils -c welcome.sln welcome_prompt 'This is a Welcome Call prompt' New prompt created with i_ivr_prompt = 30 |
The prompt is ready. Now assign this prompt to the accounts:
| UPDATE accounts SET welcome_call_ivr = 30 WHERE ... |
