The phone number for EDD is
1-800-300-5616,1,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,11 (some suggest 24, but that's technically an abuse that attempts to contact a different department for employers. 121 would be a more appropriate set of options, but that injects additional recordings and leads to same queue).
The system has an an unskippable 1:30 greeting, which causes enormous waste of time.
If you have to figure out how to program a phone to press buttons after a 1:30 timeout, the system is broken.
If you call on TTY, which is a functional text interface, they will eventually answer and then claim abuse and disconnect. That is likely an ADA violation.
Your odds of reaching a person are worse than winning a radio contest before they switched to text. My 8 hours of call logs prove it.
I am tempted to make a Twilio script. If call dropped, redial, else connect human. I bet you that's how these services operate.
