Add the login server as STUN server to spark.properties
Description
I was able to get back a Call to PC button on my Spark 2.6.0 by enabling STUN service on Openfire and then adding
stunFallbackHost=my_servername
to spark.properties
Wonder. Maybe we can do this automatically (adding a fallback string with login server's name), so one will only need to enable STUN on their server to make Call button appear in all Spark clients logged in to that server.
