Call Capacity
Maximum number of calls allowed on this trunk group.
Choices: 1-15 or unlimited (16 calls). Default is unlimited.
Both incoming call and outgoing call are counted towards
this limit. The call capacity has the following impact on call
handling:
• Inbound calls: When the limit is reached, the Trunk SUA
replies 486 to the caller.
• Outbound calls: When the limit is reached, the Line SUA plays
a fast busy tone to the caller. Note that a trunk line can make
an outgoing call only through its own trunk. If that trunk
reaches full capacity, it will not attempt to failover to use other
trunks
