Router(config-voiceport)# timeouts interdigits seconds

Specifies the number of seconds the system will wait

For more information on specific voice-port configuration commands or additional voice-port commands, refer to either the Cisco IOS Release 12.0(3)T Voice over IP for the Cisco AS5300 feature module or the Cisco IOS Release 12.0 Voice, Video, and Home Applications Command Reference..

Verifying Voice Port Configuration

•Use the show voice port command to verify that the data configured is correct.

•If you have not configured your device to support direct inward dial, dial in to the router and see if you have dial tone.

•Enter DTMF digit. If the dial tone stops, you have two-way voice connectivity with the router.

Troubleshooting Tips

If you are having trouble connecting a call, and you suspect the problem is associated with voice-port configuration, you can try to resolve the problem by performing the following tasks:

•Ping the associated IP address to confirm connectivity. If you cannot successfully ping your destination, refer to the “Configuring IP” chapter in the Cisco IOS 12.0 Network Protocols Configuration Guide, Part 1.

•Check to see that the VFC has been correctly installed.

•Use the show dial-shelfcommand to see if the VFC is operational.

•Use the show vrm vdevices summary command to verify that you have voice devices available.

•Use the show isdn status command to view layer status information. If you receive a status message stating that Layer 1 is deactivated, make sure the cable connection is not loose or disconnected. (This status message indicates a problem at the physical layer.)

•With T1 lines, check to see if your u-law setting is correct. With E1 lines, check to see if your a-law setting is correct. Use the cptone command to configure both a-law or u-law values. For more information about the cptone command, refer to the Cisco IOS Release 12.0(3)T Voice over IP for the Cisco AS5300 feature module.

•If dialing cannot occur, use the debug isdn q931 command to check the ISDN configuration.

AS5800 specifications

Cisco Systems has long been a leader in the networking and telecommunications field, and its AS5800 series of routers exemplify this tradition. The AS5800, along with the AS5850, AS5350, AS5400, and AS5300, provides robust solutions for service providers and enterprise-level networking applications. Each of these models has distinct features and characteristics that cater to the evolving demands of internet traffic and data processing.

The Cisco AS5800 is designed for high-capacity routing and optimized for broadband services. It supports a wide range of services, including voice, data, and video applications, making it a versatile option for service providers looking to deliver integrated solutions. It is equipped with advanced quality of service (QoS) features that ensure bandwidth is allocated effectively, holding strong even under heavy traffic conditions.

In comparison, the AS5850 offers superior processing capabilities and is typically utilized in larger-scale implementations. This model supports high-density interfaces, allowing numerous connections without compromising performance. Its architecture includes enhanced MPLS (Multiprotocol Label Switching) support, enabling more efficient traffic management and better utilization of network resources.

The AS5350 is known for its scalability and energy efficiency, ideal for voice-over-IP (VoIP) and media gateway applications. It supports various telephony features, such as protocol interworking and transcoding, making it a preferred choice for organizations focusing on digital voice technologies. The AS5300, while slightly older, continues to be a valuable asset for less demanding networks, offering reliable performance with VoIP capabilities and basic data applications.

The AS5400 bridges the gap between high-performance routing and operational efficiency. It incorporates Cisco's proprietary technologies to ensure seamless connectivity and robust failover systems. This model is highly regarded for its security features, protecting network integrity and providing peace of mind for businesses relying on sensitive data transfer.

Overall, Cisco’s AS5800 series showcases a progressive evolution of routing capabilities with enhanced features tailored for resilience, scalability, and performance. These routers not only address the technical needs of modern networks but also strategically position organizations for future growth in an increasingly digital world. Each model, with its unique attributes, continues to support the varied demands of global communication infrastructures.
