generate
Generates a fixed length call ID using the specified dictionary. Note that this function generates pseudo-random identifiers via regular java.util.Random and should not be considered as cryptographically secure. Also note that you need to use the same dictionary for CallIdVerifier, otherwise a generated call ID could be discarded or may lead to complete call rejection.
