asterisk users - Mar 2018 - pjsip trunk config question + DNS related error messages

Greetings,


I am getting the following error (below) continually in my asterisk log, related
to qualify_frequency I believe. I am trying to use sip trunking with the company
flowroute.

3 questions if I may:

1) Is using qualify_frequency with a sip trunk a common or recommended practice?
I figured it would function as a keep-alive and keep the ?pjsip show endpoints?
availability data up-to-date if I wanted to check on the health of the trunk.
Sound right?

2) Any idea what this error means? Googling showed almost nothing except one
other post to this list for a bug that was fixed in 14 , I?m on 15.x

3) Any other recommendations for this trunking config?


Thanks very much ! Especially jcolp and gtjoseph for answering my queries in the
past, sorry if I don?t always respond again as I haven?t actually figured out a
good way to do that unless I am subscribed to receiving all mails from the list.

Is there any reason you aren't just using sip:flowroute.com here?

PJSIP does SRV resolution so that'll use SRV instead which I know works.
