bbb-voice was responding the Freeswitch REINVITE with 200 OK containing remote SDP and with no media description.

The 'From' field must contain bbb-voice IP. We were getting Freeswitch IP instead (that is ok ONLY when bbb-voice and Freeswitch share the same machine with same IP Address).

try to speedup getrecordings, could reduce from 35s to 25s, but it's still not enough; need to better understand where's the bottleneck

Fixed audio connection problem. Maybe this timer made sense when WebRTC audio connection wasnt being transferred after echo check

Fixed the bad alignment of the components. Implemented the saving of new layout by Enter Key in the TextInput field.
