[Freeswitch-users] STUN Binding request times out after 200 OK received on client

I understand this is not jira. I wasn't really sure this was a bug or user
error.
If indeed it is a bug shouldn't the OP open a jira?

I'm about to leave for 1 week, so I won't be able to update to master this
week. I'll give it a try next week to see if the issue remains.

And the CS in playstore is dated from November. The current nightlies fixed
a timing error with ICE a few weeks ago. Maybe that fix broke compatibility
with FS?

If someone else could test with the latest nightly to confirm the issue, it
would be a big help in narrowing down the source of the problem.

Cheers,

Peter
