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 routers have edge networking capabilities and provide reliable, secure branch office connectivity. They offer an aggregate data throughput of up to 100mb/s which can also be upgraded to 300mb/s.

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.

Our organization had the requirement of having redundant internet links to improve the uptime of internet connectivity at our plant and head office. Therefore, we needed a robust and reliable WAN router that also supported BGP to provide auto-failover between primary and secondary internet links. The Cisco ISR 4000 series router met our requirements perfectly, and it has been working flawlessly since its deployment.

This equipment is very versatile, including the ability to install modules, [and] to allow one piece of network gear to manage and facilitate added services. [It does this] without [the] need to buy other hardware and support services. This enables us to have a very high number of "9s" uptime for all of our user community scattered across our offices. We use [this] kind of router [in] our remote locations as well, and it [works] perfectly fine.

It is used as a WAN router or some call it a perimeter router, before we didn't have any router at WAN edge. The main need of this router is to create IPSEC over GRE tunnel between my regional branches and [Cisco 4000 Series Integrated Services Routers (ISR 4000)] [works] very well for my organization.

We have a High Availability pair in place as if routers. We are able to use these to do many different things including landing VPNs and BGP. These are our routers on our primary site. We have had great success with the Cisco product line and are not planning on moving off of it.

We use Cisco 4000 Series Integrated Services Routers (ISR 4000) for our WAN connectivity including sub-services of WAAS, UCS-E blades (running VMware ESXI) inside them and the LTE NIM cards (for failover backup Internet). We also, at our hub end, use these for voice gateway services for our VOIP phone infrastructure. This equipment is very versatile, including the ability to install modules to allow one piece of network gear to manage and facilitate added services without needing to buy other hardware and support services. This enables us to have a very high number of "9s" uptime for all of our user community scattered across our offices.

My place of business was tasked with upgrading the core routers of the network to give us an overall faster network with less old hardware barely hanging on by a thread. We had some routers that were running for almost 10yrs straight and were on their last legs. We went all out and replaced the majority of them with the [Cisco 4000 Series Integrated Services Routers (ISR 4000)].

Most Cisco shops use a strong Cisco branded switching and routing backbone. Our company is no different. About every 3 years we upgrade to the latest Cisco routers and the Cisco 4000 Series Integrated Services Routers (ISR 4000) was our latest upgrade in the router sector. They have been implemented throughout the organization and are now being used to replace problematic voice routers as well.

Cisco 4000 Series Integrated Services Routers [(ISR 4000)] helped provide our organization with a secure WAN connection for our remote sites. There were no issues so far as we use it across our whole organization. It is easy to set up with a nice default configuration. As it supports SD-WAN technology, we find almost no issues with the product deploying in the USA.

[Cisco 4000 Series Integrated Services Routers] (ISR 4000) is being used by the whole organization in places where we needed a solid router choice. Competitors like Aruba and Juniper typically have solid devices, but I would put the Cisco's on a different level. Price of course is a concern, but overall the Cisco's are worth the price when they solve problems like we had (manageability, scalability, security, reliability).

It's being used across the whole organization. We already had the old router 3945E and we reached the limitation of bandwidth for this box. We were searching for another scalable box and we found that the 4451 is the most perfect one. It could be upgraded just using a license without the need to change hardware.

We are using the Cisco 4000 Series Integrated Services Routers at our remote sites and the Cisco 4000 Series Integrated Services Router is a nice little unit to fit in where you need local routing and for WAN connection. Utilizing it as a gateway in Cisco Unified Call Manager works too! It is a nice config, install, and it just runs kind of hardware!

We are using Cisco ISR 4451 routers as the head-end routers for our agency-wide WAN. We use them to terminate ISP and MPLS tunnels from all our remote sites and are in the process of setting up pfr. We also use them as our agency-wide NTP servers. They have allowed us to scale up our connections to remote locations.

Three years ago we decided to upgrade our internet circuits from 100Mbps to 500Mbps, so we also decided to upgrade our routers from 3945 to 4451 in order to support VPNs, B2B, DMZ, O365 traffic, so far everything has been working fine, no outages, no issues with these models. We have deployed the same models in different regions (Americas, EMEA and APAC).
