Calling party/billing number

•
Music on Hold
Playing of music for the Music on Hold feature requires access to a music source. If that music
travels over a WAN link, then the bandwidth used must be considered. Since there is no need for
the music source to receive a voice path, only one direction of talk path must be taken into
account.
•
RSVP
The CAC-BL and RSVP features operate independently. The RSVP feature allows calls to reserve
bandwidth of a certain quality, but does not preclude calls from using WAN links if they cannot be
guaranteed the quality. The CAC-BL feature can be used in conjunction with the RSVP feature to
additionally prevent calls from using those oversubscribed WAN links.
•
Shuffling
Different paths through the network regions are used between endpoints when the call is in the
IP-direct state (no VoIP resources required) and when the call is in the IP-TDM state (VoIP
resources are required). The CAC-BL feature adjusts bandwidth usage to account for calls being
shuffled between IP-direct and IP-TDM states. This calculation of bandwidth usage takes into
account what network regions the endpoints are in and what network regions the VoIP resources
are in for the IP-TDM state. The CAC-BL feature blocks connections from shuffling between
IP-direct and IP-TDM states if, after computing the revised WAN resource usage, the bandwidth
limits are exceeded.
•
Transfer
Initiating a transfer requires another call appearance to dial another party (or to select another
party on hold). Therefore, the CAC-BL feature must be able to block the transfer, if dialing that
other party would cause bandwidth limits to be exceeded. The CAC-BL feature also must be able
to block the transfer, if transferring the call would cause bandwidth limits to be exceeded.

Calling party/billing number
Calling Party Number/Billing Number (CPN/BN) allows the system to request CPN/BN information
from an AT&T network. The CPN is the calling party's telephone number. BN is the calling party's
billing number. The CPN/BN may contain international country codes. CPN/BN can be used with an
adjunct application.
