What is a Cisco dial peer?
Configuring dial peers is the key to implementing dial plans and providing voice services over an IP packet network. Dial peers are used to identify call source and destination endpoints and to define the characteristics applied to each call leg in the call connection.
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).
How do I check dial peer on Cisco voice gateway?
You can test your dial-peer with the command show dialplan number xxxphone numberxxx. If the call is active you can check used dial-peer with the command show voice call status.
What is the primary difference between POTS and VoIP dial peers?
In most cases, POTS dial peers are used to connect a physical voice port to a PBX, a telephone, or the PSTN. 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 are the matching criteria for incoming dial peers and outgoing dial peers in their order of preference?
Matching Inbound and Outbound Dial Peers
- Match the dialed number (DNIS) using the incoming called-number dial-peer.
- Match the caller ID information (ANI) using the answer-address dial-peer configuration command.
- Match the caller ID information (ANI) using the destination-pattern dial-peer configuration command.
What is dial-peer in Cube?
CUBE allows VoIP-to-VoIP connection by routing calls from one VoIP dial peer to another. As VoIP dial peers can be handled by either SIP or H. 323, CUBE can be used to interconnect VoIP networks of different signaling protocols.
What is destination pattern 9T?
The router pauses to collect additional dialed digits. For example destination-pattern 9T matches the digit 9 followed by zero or more digits- it will route the call only after the expiry of the inter-digit timeout.
Which command is useful to see if dial peers are configured on a CME router?
To display configuration information for video dial peers, use the show dial-peer video command in privileged EXEC mode.
What is destination-pattern 9T?
What is dial plan in VoIP?
A VoIP dial plan is the path an inbound call will take through your phone system. A dial plan is usually mapped out online using a dial plan editor on your VoIP service provider’s portal. Dial plans go by many names: call tree, call path, call flow, and call route to name a few.
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).
Which one is the configurable parameter used for matching inbound dial peers?
DNIS number This command uses the destination number that was called to match the incoming call leg to an inbound dial peer. This number is called the dialed number identification service (DNIS) number.
What is dial peer in VoIP?
Voice over IP (VoIP) – The dial peer is mapped to the IP address, Domain Name System (DNS) name, or server-type of the destination VoIP device that terminates the call. This applies to all VoIP protocols such as H.323, SIP, and Media Gateway Control Protocol (MGCP).
What is the Cisco IOS command for dial peer configuration?
The Cisco IOS command to enter into the dial peer configuration mode is: A voice call over a packet network is segmented into discrete call legs. These are associated with dial-peers (a dial-peer is associated with each call leg).
How are calls routed in POTS dial peers?
If the dialed string matches the destination pattern, the call is routed according to the voice port in POTS dial peers, or the session target in voice-network dial peers.
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.
