Bluetooth Speaker - Grandstream Networks GSC3516 User Manual

In the case of receiving a multicast paging call while on a unicast SIP call, the GSC3516/GSC3506 can choose to either keep
the SIP call or hold this last and allow the multicast call depending on the paging call priority.
This can be set using the "Paging Barge" option. If the option is set to "Disabled" all incoming multicast paging calls will be
dropped while on a SIP call. If the multicast paging call has higher priority than the value set on "Paging Barge", the SIP call
will be put on hold and GSC3516/GSC3506 will be the incoming multicast paging.
Note
The start and end of multicast tones have been removed from the multicast configuration starting from firmware 1.0.3.4

Bluetooth Speaker

Note
The bluetooth feature is available only on the GSC3516 Speaker model.
The GSC3516 can be used as a Bluetooth speaker for another device and it needs to be connected via Bluetooth to that
device. Users need to turn on GSC3516's Bluetooth function first. The first time when using a new Bluetooth device with the
GSC3516, "pair" the device with GSC3516 so that both devices know how to connect securely to each other.
