devices, a DSP resource on a Media Card is allocated and connected to the

returned to the main office Call Server so a direct media path between the
IP Phone and the DSP resource can be set up when the call is established.

Conference calls

When an SRG user initiates a conference call, the conference facilities of the
main office are used. This means that in a conference among three SRG users,
the LAN/WAN bandwidth of three media paths is used. The calls are
controlled by the main office, except in Local Mode. In Local Mode, SRG
users do not have access to conferencing.
