During long call we are facing mic’s hanging issue. Currently we have three mic’s on this location & its connected with each other 1 to 1. At least 3 to 4 times we observed this issue. Lights starts to blink & remote site unable to listen us, until we restart the RP200.
1. check the DIP switch ok
2. check the version of VPM210 ok
3. upgrade the version of three VPM210, the problem solved.
1. when cascaded the VPM210, we have to adjust the mic DIP switch
2. by using terminal to check the version of the VPM210 one by one.
upgrade the version can solve some strange issue.
