Manually operate a cross province conference, find out terminals in province, can join the conference normally, terminals outside the province can’t join the conference.
When we have to operate conference across the province manually, we need to operate all the terminals in this province, then, after the conference is started, add the terminals outside the province;
We set main MCU when manually operate, because Main MCU is local MCU, the terminals called is terminals outside the province. They can’t be local changed, so the call was hanged up.
Try to use automatically operate the conference, if we have to use manual method to operate conference across province, we should operate this province’s meeting places, then add meeting places outside the provinces.
