I open a new topic, because the topic was previously opened for a different problem.
this day dawned all openvox strange, sometimes when a call is to be made, the ringing tone is not transmitted and silence is heard only audio is heard when answered, no ringback is heard,
I tried adjusting the inband to yes, and I see that by default have openvox prematuremedia = no, everything I see, the problem is that not all options and not all the time. It is very rare, last night 3 Openvox update to version 2.1.1 and perform the factory reset process and returned to configure the clusters, but there was no improvement, I made a downgrade of one of the Openvox to version to 2.0. 9, but the problem persists. discard my server, because when redirected calls to an outsourcer they function properly.
