What is dial-peer voice?

A dial peer, also known as an addressable call endpoint, is a device that can originate or receive a call in a telephone network. Voice-network dial peers include VoIP-capable computers, routers, and gateways within a network.

What is the difference between VoIP and POTS dial-peer?

The POTS dial peer maps a dial string to a voice port on a local router or gateway. VoIP a dial peers are used to define packet voice network attributes and map dial strings to a remote router or device. The following sample configurations provide basic examples of POTS and VoIP dial peers.

What is a dial-peer and why is it used?

Voice over IP dial peers includes VoIP capable computers, routers, and gateways in a network. POTS dial peers include traditional telephone devices such as phone sets, cell phones, and fax machines. Dial peers are used to configure dial plans and to identify call source and destination endpoints.

What are the types of dial-peer?

The four types of voice-network dial peers (VoIP, voice over ATM (VoATM), voice over Frame Relay (VoFR), and multimedia mail over IP (MMoIP)) are determined according to the given packet network technology and are described as follows: VoIP—Points to the IP address of the destination router that terminates the call.

What are dial-peer wildcards?

These wildcards are most often used when creating dial plans for PSTN access….Using Dial Peer Wildcards.

Wildcard Description
phone keypad. For example, 20.. matches any number from
2000 through 2099.
Plus (+) Matches one or more instances of the preceding digit. For
example, 5+23 matches 5523, 55523, 555523, and so on. This

What is dial-peer preference?

The dial peer attribute destination-pattern has different behavior when applied to inbound or outbound call legs: For inbound dial peers, the destination-pattern is matched against the calling number (ANI string). For outbound dial peers, the destination-pattern is matched against called number (DNIS string).

What is the difference between PABX and PBX?

The difference between a PBX and PABX is quite simple. A PBX is a “ private branch exchange,” while a PABX is a “ private automatic branch exchange.” The only difference is the word “automatic.” When electronic switching became available, the automatic telephone system was born – the PABX.

Is VoIP better than PSTN?

In the PSTN vs. VoIP debate, PSTN is viewed as more reliable and secure than VoIP networks. PSTN also offers better business continuity, as the connection is not interrupted during a power outage. When VoIP technology first emerged, it was notorious for dropped calls and poor call quality due to jitter and latency.

What happens if there is no matching dial peer for an outbound call?

If no incoming dial peer matches the calling number, the inbound call leg automatically matches to a default dial peer (POTS or VoIP).

How do I configure incoming dial peer?

The steps for matching inbound dial peers are as follows:

  1. Match the called number to the incoming called number that is configured on the dial peers.
  2. Match the calling number to the answer address that is configured on the dial peers.

Why would you use wildcards in dial peers?

Using wildcards should reduce the time and condense the number of dial peers for a particular dial plan.

What happens if there is no matching dial-peer for an outbound call?

What is the default codec value for VoIP dial peers?

The default codec value for VoIP dial peers is G.729. Finally, notice that the dial peer 1100 on ROUTER_B uses the command destination-pattern 110. to direct all calls starting with the digits 110 to the CME_A router.

What is a dial peer?

A dial peer is the physical implementation of a call leg, and as stated in the last paragraph, there are two call legs and thus two dial peers to be configured on each router. Depending on the type of call leg, there are two different types of dial peers that can be configured; these include:

How do I assign voice ports to dial peers?

Assigning voice ports to dial peers identifies the physical hardware in the router that will be employed to complete voice communication to and from associated voice network endpoints. The purpose of this task is to assign a voice port to a plain old telephone system (POTS) dial peer. Enters privileged EXEC mode. Enter your password if prompted.

What is the difference between pots and VoIP dial peer configuration?

The primary difference between the POTS and VoIP dial peer configuration is the use of the session target command rather than the port command. When you use the context-sensitive help after the session target command, the router simply replies with WORD. This means that whatever you enter after the command is somewhat freeform.
