I have set up a voice mailbox in the application and still in case of rejected call, the caller goes to primary number voicemail.

A subscriber may have set up via device settings for a call to go to a voicemail in case of no answer, rejected or busy.As for Num2, forward to voicemail according to those settings is considered as an answered call. The subscriber can control this by going to call settings and turning off the call forward. (Not all mobile operators allow editing those settings).
