v6.2.1

SpamBlocker Extended 6.2.1

Fixes:

• Answer + Hang Up could fail on some devices (e.g. CalyxOS) because the ringing event arrived too late. Reverted the 6.1.5 change, as upstream did in 5.19.
• Calls reported with an unknown direction are now screened and logged instead of being skipped.
• Caller numbers in SIP format (e.g. "sip:+49...@Ims...;user=phone") now match rules and contacts.
• A call always gets a screening response, even if screening hits an error.

Improvements:

• An empty spam database search lists private numbers first.
• Updated phone number library and build tools.
