UNIVERGE SV8100
When the phone is set to Unicast Mode the internal paging is sent to the phone via a
Unicast Packet.
When the phone is set to Multicast Mode the internal page is sent to the phone via a
Multicast Packet.
When the phone is set to Auto, the internal page is sent to the phone either by
Multicast or Unicast based on the subnet of the IP station. If the DT7XX terminal is in
the same subnet as the IPLA then it will receive the Internal Page via a Multicast
Packet. If the DT7XX terminal is in a different subnet than the IPLA the DT7XX will
receive the Internal Page via a Unicast Packet.
When phones are set to receive Unicast packets the IPLA will send a separate RTP
stream to each phone that is set to receive the page. E.g. If there are five DT7XX IP
phones in the page group and they are all set to Unicast Page Mode the IPLA will
send five separate RTP streams utilizing five DSP resources.
When the phones are set to receive Multicast packets the IPLA will send one RTP
stream. Multicast is a protocol that allows one device to communicate to multiple
devices without the need to stream to the individual end point. E.g. If there are five
DT7XX IP phones in the page group that are set to Multicast Mode, the IPLA will send
one RTP stream utilizing only one DSP resource.
Uniform Call Distribution (UCD)
With Uniform Call Distribution (UCD), an extension user can call an idle extension in a
programmed UCD Group (Department Group – 64 Department Groups available) by
dialing the group pilot number. For example, this would let a caller dial the Sales
department just by knowing the Sales department pilot number. The caller would not
have to know any Sales department extension numbers.
User Log Out/Log In
An extension user can log out and log in to a UCD (Department) group. By logging
out, the user removes their extension from the group. Once logged out, UCD
(Department Calling) bypasses their extension. When they log back in, UCD
(Department Calling) routes to their extension normally. All users can dial a code to
log in or log out of their UCD (Department Calling) Group. A multiline terminal can
optionally have a function key programmed for one-button log in and log out.
Enhanced Hunting
UCD (Department Calling) is enhanced with expanded hunting abilities. Hunting
defines how calls to a UCD (Department Group) pilot number cycle through the
members of the group. The hunting choices are:
