I have installed openfire as my jabber server and spark as my jabber client.
and the version of jabber client Spark is spark_2_5_8.
I am able to make IM, transfer of files but i am not able to answer the call.
the error is “session cloed due to Closed Remotely” on one side and
on the other side we are getting “Voice chat ended: No Media Recieved. This may be caused by firewall configuration Problems”.
we have tested even disabling the firewall also.
even though same error.
please give me any idea regarding this.
