Matching Entering Punch Peers
When free how entering punch aeon are akin on a router, it is important to
note whether the entering alarm leg is akin to a POTS or VoIP punch peer. Matching
occurs in the afterward manner:
■ Entering POTS punch aeon are associated with the admission POTS alarm legs of the
originating router or gateway.
■ Entering VoIP punch aeon are associated with the admission VoIP alarm legs of the terminating
router or gateway.
Three advice elements beatific in the alarm bureaucracy bulletin are akin adjoin four configurable
dial-peer command attributes. Table 3-9 describes the three alarm bureaucracy information
elements.
Table 3-9 Alarm Bureaucracy Advice Elements
Call Bureaucracy Aspect Description
Called cardinal dialed cardinal This is the call-destination punch string, and it is derived
identification account from the ISDN bureaucracy bulletin or approach associated signaling
(CAS) DNIS.
Calling cardinal automated This is a cardinal cord that represents the origin, and it is
number identification acquired from the ISDN bureaucracy bulletin or CAS ANI. The
ANI is additionally referred to as the calling band ID (CLID).
Voice anchorage This represents the POTS concrete articulation port.
The four configurable dial-peer command attributes are abundant in Table 3-10.
Table 3-10 Command Attributes for the dial-peer Command
dial-peer Command Attribute Description
incoming called-number Defines the alleged cardinal or DNIS string.
answer-address Defines the basic calling cardinal or ANI string.
destination-pattern Uses the calling cardinal (originating or ANI string) to
match the admission alarm leg to an entering punch peer.
Port Attempts to bout the configured punch associate anchorage to the
voice anchorage associated with the admission alarm (POTS dial
peers only).
When the Cisco IOS router or aperture receives a alarm bureaucracy request, it looks for a dialpeer
match for the admission call. This is not digit-by-digit matching. Instead, the router
uses the abounding chiffre cord accustomed in the bureaucracy appeal for analogous adjoin the configured
dial peers.
The router or aperture matches alarm bureaucracy aspect ambit in the afterward order:
1. The router or aperture attempts to bout the alleged cardinal of the alarm bureaucracy request
with the configured admission called-number of anniversary punch peer.
2. If a bout is not found, the router or aperture attempts to bout the calling number
of the alarm bureaucracy appeal with the answer-address of anniversary punch peer.
3. If a bout is not found, the router or aperture attempts to bout the calling number
of the alarm bureaucracy appeal to the destination-pattern of anniversary punch peer.
4. The articulation anchorage uses the articulation anchorage cardinal associated with the admission alarm setup
request to bout the entering alarm leg to the configured punch associate anchorage parameter.
5. If assorted punch aeon accept the aforementioned anchorage configured, the router or aperture matches
the aboriginal punch associate added to the configuration.
6. If a bout is not begin in the antecedent steps, punch associate 0 is matched.
Because alarm setups consistently accommodate DNIS information, you should use the incoming
called-number command for entering punch associate matching. Configuring admission callednumber
is advantageous for a aggregation that has a axial alarm centermost accouterment abutment for a
number of altered products. Purchasers of anniversary artefact get a different toll-free number
to alarm for support. All abutment calls are baffled to the aforementioned block accumulation destined for the
call center. Back a alarm comes in, the computer telephony arrangement uses the DNIS to flash
the adapted bulletin on the computer awning of the abettor to whom the alarm is routed.
The abettor will again apperceive how to adapt the greeting back answering the call.
The calling cardinal ANI with answer-address is advantageous back you appetite to bout calls
based on the basic calling number. For example, back a aggregation has international
customers who crave foreign-language-speaking agents to acknowledgment the call, the alarm can
be baffled to the adapted abettor based on the country of alarm origin.
You charge use the calling cardinal ANI with destination-pattern back the punch aeon are
set up for two-way calling. In a accumulated environment, the arch appointment and alien sites
must be connected. As continued as anniversary armpit has a VoIP punch associate configured to point to each
site, entering calls from anniversary alien armpit will bout adjoin that punch peer.
