Asterisk 13.3.2 res_pjsip_pubsub warning

Hi,

In cli I have, for each endpoint, many warnings like this:

res_pjsip_pubsub.c:2870 pubsub_on_rx_publish_request: No registered publish handler for event presence

What is the meaning of it? How can I solve the “problem”?

Thank you…

What problem is it causing?

I have no problem, I would like to know why I have this warning…

Thank you

PJSIP has received a subscribe request for the event named “presence”. It either has no idea how to deal with this event, or, possibly, has not been configured to handle it.

ietf.org/rfc/rfc3856.txt for what the event means.
