The PJSIP modules will prune expired contacts in two cases:
1. When being asked to retrieve contacts for something
2. If the res_pjsip_registrar_expire module is loaded then contacts will 
be pruned in real time (it will grab all contacts at load, and as stuff 
registers to the Asterisk instance it will become aware of them)

I don't understand what you mean by cache.

This does not currently exist in the PJSIP functionality.
