Summary
The capital capacity covered in this affiliate are the following:
■ Chiffre abetment is the assignment of abacus or adding digits from the aboriginal dialed
number to board user dialing habits or aperture needs.
■ Chiffre stripping strips any outbound digits that absolutely bout the destination pattern
of a accurate punch peer.
■ Chiffre forwarding specifies the cardinal of digits that charge be forwarded to a telephony
interface.
■ Chiffre prefixing adds digits to the advanced of the punch cord afore it is forwarded to a
telephony interface.
■ Cardinal amplification is activated globally to all calls, not aloof to calls analogous a single
designated punch peer.
■ By default, back a absolute router matches a punch cord to an outbound POTS
dial peer, the router strips off the left-justified digits that absolutely bout the destination
pattern.
■ You can use the clid command to adapt addition ID information.
■ You can use articulation adaptation profiles to alter the Cisco Unified CME dialplanpattern
command.
■ Configuring chiffre abetment ability crave the use of basal commands as able-bodied as
translation rules and profiles.
■ The alarm acquisition argumentation on Cisco IOS routers application the H.323 agreement relies on the
dial associate construct.
■ Routers charge bout the actual entering and outbound punch aeon to successfully
complete a call.
■ Punch aeon in a coursing accumulation are called according to belief such as longest match,
explicit preference, or accidental selection.
■ Best practices accommodate a absence POTS punch associate and bombastic Cisco UCM.
■ Back alien sites are involved, altered aisle alternative strategies are required,
including site-code dialing, toll-bypass, and TEHO.
■ Site-code dialing uses the abstraction of prefixing a armpit cipher in advanced of the actual
extension and can be accumulated with toll-bypass to avenue calls over a WAN link
instead of a PSTN connection.
■ TEHO extends the abstraction of toll-bypass by acquisition calls over a WAN to the closest
PSTN blemish to abstain cher long-distance and all-embracing buzz charges.
■ Site-code agreement requires that anniversary armpit be assigned a different armpit code.
■ TEHO agreement requires that all calls be baffled over the WAN unless the WAN
is down.
■ Calling privileges are acclimated aural a punch plan to ascertain the destination a user is
allowed to call.
■ Calling privileges are implemented on Cisco IOS gateways application the Class of
Restriction (COR) feature.
■ For Cisco Unified CME, a corlist is anon assigned to an adapted ephone. To
assign a corlist in SRST mode, a corlist is akin to a ambit of agenda numbers in
Communications Manager fallback agreement mode.
■ Configuring COR includes configuring called CORs and corlists, and assigning
corlists to punch peers, ephones, or SRST.
