Hello,
I've tested the patch using the same settings that I've posted, and it looks
like it works as intended; specifically:
-- Contacts registered on UDP will receive an OPTIONS packet periodically
-- Contacts registered on TCP will not receive any OPTIONS packets.
-- Contacts registered on TCP are NOT triggering the "usrloc:contact-expired"
event within the ka_timeout period
Thank you.
