GOautodial Open Source Omni-channel Contact Center Suite

When an agent logs in, he selects the campaign and his phone registers correctly, but the phone on the right does not appear. When the agent logs in again with his phone, then this appears. In this case, however, the agent hears his own voice, as if there were 2 open conferences on the same phone. I also have another problem with the advanced campaign settings. I select the country, save the settings, but "united states" is always selected.
