SWe use this product in my organization like we do OSPF routing between office location and we do BGP routing to pair between ISP.

We use them for our wide area network because we have two redundant wide area networks. We have a hundred meg link coming off the sites, terminated our data centers. We use this product for that kind of connectivity between the regional sites and also the data center. At the regional sites, we have the Cisco 4300 series and at the data center, we have the Cisco 4000 series. That's why we use our end-to-end connectivity using those devices.

We mainly use it not for data, but mainly for voice. It's our platform for Cisco call manager, voice over ip.

It takes care of providing the WAN connections for our network. So it's the WAN connectivity.

I use these to enable communications from field sites on the corporate network via Internet, Cell, Satellite, MPLS.

As a membre of the network team in the Cloud Business Unit of Orange Business, we are using those router at our customer premises for remote console access and they are doing the job perfectly.

Other uses cases, where we use them for routing purpose.

The only faced problem, is the high lead time to get them.

We are currently using Cisco 4000 Series Integrated Services Routers as our voice gateway routers at our branch offices. These routers allow us to connect directly to telco PRIs so that our branch offices have phone services. We also use them as our backup WAN router if the primary WAN router would ever happen to go down.

We use the routers in my organization primarily as voice gateways. Many of our locations still use legacy PRI (serial/copper) handoffs from our vendors and we need a gateway in order to receive the connections. The other primary function that they serve is to be the coordinator for SRST for our Cisco phones. If the phones lose connection to Call Manager, the ISR4300s we have will take over call routing duties so our office can continue to receive calls even though they have been isolated from the subscribers. At some of our smaller locations, we also use them for some basic core routing functionality. They are certainly capable of handling all of the duties in one appliance and are a good value.

We use Cisco ISR 4000 series routers for the SD-WAN branch network. They offer a great quality of service with increased bandwidth and throughput.

Cisco ISR 4000 Series features simple, easy-to-understand commands. To create the best possible routing engine, they also provide outstanding features. We have used this series of routers in both locations. On the device, we’ve configured routing, switching, and application visibility. In some of our branches, it serves as the default gateway. As a company, we needed a dependable router that could provide a strong IPSec-site-to-site VPN. AES-256 encryption is used to secure the network and it works with non-Cisco equipment in multi-vendor deployments. We can find a lot of information about these products and services online.
