I am facing problem with Spark Computer to computer voice call. Presently i am using Spark version 2.6.0 on windows 7 and Xp OS. and open fire version 3.7 on wndows 2008 server. when i try to call computer to computer it give error " session clodes due to no media received. this may be cased by firewall configuration problem," but i turned off OS firewall and both computers are in same intranet network [un mamaged],
How Can i resolve this problem.
Thanks in advance,
