Resource Allocation
When device B hangs up to complete the transfer, the system may optimize the route
such that the system uses only DSP W on node 1 and DSP Z on node 3 to make the
audio connection. However, the system does not release DSP X and DSP Y on node 2
for use by other calls.
NOTE: Additional DSPs may be consumed if a call is transferred to multiple locations.
• Multiple Ring-In Calls: The system reserves DSP resources for each leg of a complex
call. However, once the call is answered, the system releases all DSPs that are allocated
for legs that no longer exist.
For example, device A on node 1 calls an All-Ring Hunt Group with three members on
Node 2. The system reserves three DSPs on each node allowing each member to receive
an incoming call ring.
If only two DSPs are available on one of the nodes, the system reserves the two avail-
able DSP pairs and rings only two members (camping onto the third DSP pair). After a
member answers the call, the system releases the extra DSPs such that only one DSP on
node 1 and one DSP on node 2 are used.
