Keep-Alive on Asterisk using PJSIP with a SIP Trunk registration.

Not sure why I found it so difficult to find this tweak but I’m going to document it here in case I need it in the future or if anyone else has the same problem.

qualify_frequency in the aor section! This causes Asterisk to send OPTION requests to keep the connection alive.

keepalive asterisk pjsip sip trunk

The normal timeout expiration setting or keep_alive_interval setting don’t seem to apply to the UDP transports?

The topic that pointed me towards this solution is here:
