Matching Outbound Punch Peers
Outbound dial-peer analogous is completed on a digit-by-digit basis. Therefore, the router
or aperture checks for dial-peer matches afterwards accepting anniversary chiffre and again routes the call
when a abounding bout is made.
The router or aperture matches outbound punch aeon in the afterward order:
Step 1. The router or aperture uses the punch associate destination-pattern command to
determine how to avenue the call.
Step 2. The destination-pattern command routes the alarm in the afterward manner:
■ On POTS punch peers, the anchorage command assiduously the call.
■ On VoIP punch peers, the affair ambition command assiduously the call.
Step 3. Use the appearance dialplan cardinal cord command to actuate which punch peer
is akin to a specific dialed string. This command displays all analogous dial
peers in the adjustment that they are used.
In Example 3-13, punch associate 1 matches any chiffre cord that does not bout the added dial
peers added specifically. Punch associate 2 matches any seven-digit cardinal in the 30 and 40
range of numbers starting with 55501. Punch associate 3 matches any seven-digit cardinal in the
20 ambit of numbers starting with 55501. Punch associate 4 matches the specific number
5550124 only. Back the cardinal 5550124 is dialed, punch aeon 1, 3, and 4 all bout that
number, but punch associate 4 places that alarm because it contains the best specific destination
pattern.

The capital capacity covered in this affiliate are the following:
■ A VoIP arrangement has seven archetypal alarm types.
■ A bounded alarm is handled absolutely by the router and does not biking over an external
network.
■ On-net calls can be baffled through one or added voice-enabled routers, but the calls
remain on the aforementioned network.
■ An off-net alarm occurs back a user dials an admission cipher (such as 9) from a telephone
directly affiliated to a voice-enabled router or PBX to accretion admission to the PSTN.
■ Articulation anchorage alarm types accommodate local, on-net, off-net, PLAR, PBX to PBX, intercluster
trunk, and on-net to off-net calls.
■ Articulation ports on routers and admission servers challenge concrete telephony switch
connections.
■ Analog articulation anchorage interfaces affix routers in packet-based networks to analog
two-wire or four-wire analog circuits in telephony networks.
■ FXS, FXO, and E&M ports accept several agreement parameters.
■ CAMA is acclimated for 911 and E911 services.
■ DID account enables callers to punch an addendum anon on a PBX or packet voice
system.
■ You can set a cardinal of timers and timing ambit for fine-tuning a articulation port.
■ The show, debug, and analysis commands are acclimated for ecology and troubleshooting
voice functions in the network.
■ Punch aeon are acclimated to analyze alarm antecedent and destination endpoints and to define
the characteristics activated to anniversary alarm leg in the alarm connection.
■ An end-to-end articulation alarm consists of four alarm legs.
■ A punch associate is an addressable alarm endpoint.
■ POTS punch aeon absorb the characteristics of a acceptable telephony network
connection.
■ Back a analogous entering punch associate is not found, the router resorts to the default
dial peer.
■ The destination arrangement assembly a blast cardinal with a accustomed punch peer.
■ Back 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.
■ Outbound dial-peer analogous is completed on a digit-by-digit basis.
