You can talk to a friend in person or on the phone to get used to the form's Q&As. I always record my calls whether the MSC records it or not.
If you record your practice calls, you can hear yourself. You can know whether you sound scripted, nervous, etc.
I use my own recordings to answer the report questions.
I used to jump on phone shops, but once some MSCs started saying only one call per shopper, I stopped. I'm not going to read/learn one job's rules for $5 or whatever the pay is. The pay has to be able to go longer than one job. Learning curve.
I will accept phone shops of jobs I've done before that don't vary or vary little.
I have also marked on my spreadsheet the phone call shop that wasn't worth the $9 it paid.
