Configure Voice over IP using a Trunk Connection

The routers on both sides of the Voice over IP connection must be configured for trunk connections. For the scenario described in Figure 11, configure Router A to support trunk connections as follows:

configure terminal voice-port 1/0/0

connection trunk +15105554000 dial-peer voice 10 pots

destination-pattern +13085551000 port 1/0/0

dial-peer voice 100 voip session-target ipv4:172.20.10.10 destination-pattern +15105554000

For the scenario described in Figure 11, configure Router B to support trunk connections as follows:

configure terminal voice-port 1/0/0

connection trunk +13085551000 dial-peer voice 20 pots

destination-pattern +15105554000 port 1/0/0

dial-peer voice 200 voip session-target ipv4:172.19.10.10 destination-pattern +13085551000

To configure virtual trunk connections in Voice over IP, use the connection trunk command. The following conditions must be met for Voice over IP to support virtual trunk connections:

Use the following voice port combinations:

E&M to E&M (same type)

FXS to FXO

FXS to FXS (with no signaling)

Do not perform number expansion on the destination pattern telephone numbers configured for trunk connection.

Configure both end routers for trunk connections.

The connected Cisco routers must be Cisco 2600 or Cisco 3600 series routers. The Cisco AS5300 does not currently support trunk connections.

Note Because virtual trunk connections do not support number expansion, the destination patterns on each side of the trunk connection must match exactly.

VoIP establishes the trunk connection immediately after it is configured. Both ports on either end of the connection are dedicated until you disable trunking for that connection. If for some reason the link between the two switching systems goes down, the virtual trunk re-establishes itself after the link comes back up.

3600 specifications

Cisco Systems 3600 is a high-performance modular router series designed for small to medium-sized enterprises and branch offices. Launched in the late 1990s, it has been widely recognized for its flexibility, scalability, and reliability. The series is part of Cisco's extensive networking portfolio and has played a vital role in delivering various services and applications while enhancing operational efficiency.

One of the main features of the Cisco 3600 series is its modular architecture, allowing organizations to customize the router according to their specific needs. The system supports various interface modules that can accommodate different types of connections, including serial, Ethernet, and DSL, which helps in building versatile network solutions. The modularity not only increases the router’s lifespan by enabling upgrades as technology changes but also supports future expansion as the organization grows.

The Cisco 3600 series routers utilize advanced routing protocols, such as RIP, OSPF, EIGRP, BGP, and IS-IS, to ensure efficient data transmission and optimal network performance. This capability allows the routers to adapt to varying traffic demands and complexities, thereby optimizing bandwidth utilization and reducing latency in communications. With extensive memory options, including Flash and DRAM, the 3600 series can handle robust data processing and support intricate routing environments.

Security is another critical feature of the Cisco 3600 series. It includes support for VPNs, firewalls, and other security protocols, providing a secure environment for data transfer. The implementation of features like Access Control Lists (ACLs) and Intrusion Detection Systems (IDS) enhances the overall security posture, making it suitable for organizations looking to protect their sensitive information.

In terms of scalability, Cisco 3600 routers can easily accommodate increased workloads and network growth. This is done through the provision of additional modules and cards to increase capacity and performance. The series can also support multiple WAN connections, enabling seamless integration with various telecommunication services.

Additionally, the Cisco 3600 series is designed for ease of management. Utilizing Cisco's IOS software, network administrators can manage and configure the routers efficiently, thanks to a user-friendly interface and extensive command capabilities. This makes troubleshooting simpler and ensures network availability remains high.

In conclusion, Cisco Systems 3600 series routers combine robust performance, security features, and scalability, making them an invaluable asset for businesses looking to maintain a reliable and efficient networking solution.
