Installed with working Call Manage Express CME 4.0. This lab is intended for SIP trunking to access the outside PSTN so you can call in and out anytime. Plus QoS video to demonstrate how to control voice traffic over WANs with QoS.
No legacy analog ports included in this lab because SIP trunking is cheaper and better.
Add legacy 2xFXS & 2xFXO for an additional $90 and run in the 2650 router.
This lab is an excellent introduction to Cisco CME Call Manager Express SIP based software PBX.
Most QoS instruction is awful, the worst I have ever seen, turning a subject of average difficulty into a total train wreck giving the student to impression QoS is more difficult than it really is. The goal of this lab is to provide tools and information to master Cisco QoS. DVD includes video demonstrating how to implement Cisco QoS and more importantly you can use this lab to practice QoS technologies in support of voice traffic. You can reduce the bandwidth of the T1 interfaces down to 56k, jam them with traffic, and use QoS to make a clear path for you voice traffic over the congested links.

Related Information
Related Cisco Support Community DiscussionsQuality of Service (QoS) is QoS is a collection of technologies which allows applications to request and receive predictable service levels in terms of data throughput capacity (bandwidth), latency variations (jitter), and delay. In particular, QoS features provide better and more predictable network service by the following methods: Supporting dedicated bandwidth.
Improving loss characteristics.
Avoiding and managing network congestion.
Shaping network traffic.
Setting traffic priorities across the network. The Internet Engineering Task Force (IETF) defines the following two architectures for QoS:
Integrated Services (IntServ)
Differentiated Services (DiffServ) IntServ uses the Resource Reservation Protocol (RSVP) to signal explicitly the QoS needs of an application's traffic along the devices in the end-to-end path through the network. If every network device along the path can reserve the necessary bandwidth, the originating application can begin transmitting. Request for Comments (RFC) 2205 defines RSVP, and RFC 1633 defines IntServ. DiffServ focuses on aggregated and provisioned QoS. Instead of signaling an application's QoS requirements, DiffServ uses a DiffServ Code Point (DSCP) in the IP header to indicate the required QoS levels. Cisco IOS® Software Release 12.1(5)T introduced DiffServ compliance on Cisco routers. For more information, refer to the following documents: Integrated Service in Cisco IOS 12.1
Implementing DiffServ for End-to-End Quality of Service
Implementing Quality of Service Policies with DSCPAn interface experiences congestion when it is presented with more traffic than it can handle. Network congestion points are strong candidates for Quality of Service (QoS) mechanisms. The following is an example of typical congestion points:Classification and Marking
IP precedence
QoS pre-classification enables you to match on and classify the original IP header contents of packets undergoing tunnel encapsulation and/or encryption.
Configuring QoS for Virtual Private Networks
Quality of Service for Virtual Private Networks, 12.2(2)T Feature ModuleThe class-based marking feature allows you to set or mark the layer 2, layer 3 or Multiprotocol Label Switching (MPLS) header of your packets. For more information, refer to the following documents:
Yes. Network Based Application Recognition (NBAR) allows you to classify packets by matching on fields at the application layer. Prior to the introduction of NBAR, the most granular classification was layer 4 Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) port numbers. For more information, refer to the following documents: Network-Based Application Recognition Q&A
NBAR Application Networking
Using Network-Based Application Recognition and Access Control Lists for Blocking the Code Red Worm
How to Protect Your Network Against the Nimda VirusSupport for NBAR is introduced in the following versions of Cisco IOS software on most platforms in 12.1(5)T You need to enable Cisco Express Forwarding (CEF) in order to use NBAR.Queueing is designed to accommodate temporary congestion on a network device's interface by storing excess packets in buffers until bandwidth becomes available. Cisco IOS routers support several queueing methods to meet the varying bandwidth, jitter, and delay requirements of different applications.The default mechanism on most interfaces is First In First Out (FIFO). Some traffic types have more demanding delay/jitter requirements. Thus, one of the following alternative queueing mechanisms should be configured or is enabled by default: Weighted Fair Queueing (WFQ)
Class-Based Weighted Fair Queueing (CBWFQ)
Low Latency Queueing (LLQ), which is in fact CBWFQ with a Priority Queue (PQ) (known as PQCBWFQ)
Priority Queueing (PQ)
Custom Queueing (CQ)Queueing generally happens on outbound interfaces only. A router queues packets that are going out an interface. You can police inbound traffic, but usually you cannot queue inbound (an exception is receive-side buffering on a Cisco 7500 Series router using distributed Cisco Express Forwarding (dCEF) to forward packets from the ingress to the egress interface; for more information, refer to Understanding VIP CPU Running at 99% and Rx-Side Buffering. On high-end distributed platforms such as the Cisco 7500 and 12000 Series, the inbound interface may use its own packet buffers to store excess traffic switched to a congested outbound interface following the inbound interface's switching decision. In rare conditions, typically when the inbound interface is feeding a slower outbound interface, the inbound interface can experience incrementing ignored errors when it runs out of packet memory. Excessive congestion can lead to output queue drops. Input queue drops have a different root cause most of the time . For more info on troubleshooting drops, refer to the following document:

Very Important Notice To Buyers With LessThan 10 Ratings!
Youare not buying a spoon!
Most of our CCNA CCNP buyers are students and still learning howto access, configure and manage Cisco equipment. Nothing we sell issimple or easy to use unless you already have experience with CiscoIOS and networking equipment. Occasionally student customers evenhave problems with items as simple as console cables.
