As Kamailio SIP Server is an open source, the major impact is on cost; it's free to use compared to any other Softswitch or server in the market. You can also customize it to your need and use the features that you need, which is one of the major plus points for the Kamailio …

Chose RingEX
While aircall can be very similar to RingEX, RingEX is easier to use on the web version, desktop app or mobile app, makes search easier and has the ability to provide the transcribe. Then, Convoso is more oriented to outbound sales calls so it's hard to get in touch with a …
Chose RingEX
CallRail has better reporting however RingEX provides more features at a better price.
Chose RingEX
Nothing to compare it with. We've used RingEX for years now.
Chose RingEX
RingEX seems to be better, because it seems to be a VOIP service, and you have more options to choose from as for features and products
Chose RingEX
I think that RingCentral's RingEX compares well with other solutions, though, they do seem less reliable than Zoom and Five9.

Against Vonage, RingCentral's RingEX is leagues ahead with more features and better call quality.
Chose RingEX
RingEX is/was much more robust and dependable during the time we used Loxo.
Chose RingEX
RingEX offers a more user friendly user interface. and reliable communication platform as compared to Vonage. We selected RingEX because it provides more value in a single platform, helping improve productivity and manage our 24/7 communication needs more efficiently.
Chose RingEX
RingEX has the best mix of positives with the fewest negatives.
Chose RingEX
RingCX was absolutely the wrong fit for us, RingEX gives up much more control over where calls are routed
Chose RingEX
Cisco was great, but it was extremely expensive for us. RingEX was much cheaper and works just as well.
Chose RingEX
Each of these products have benefits, some of which relates specifically to the specific needs of a company. We liked the call recording options in Hubspot and the workflow tracking in Monday. High Level wasn't the best fit for our needs. In the future, we anticipate using …
Chose RingEX
We are using these products like (Skype, Voip, TextNow, and Second line), but comparatively these products the RingEX has a good performance, because while we were using the other platform, we didn't get proper communication, we couldn't reach out the candidate, we lags to much …
Chose RingEX
We have looked at all the competition and none come close to providing the ease of use and efficiency we have found with RingEX. We appreciate how they are constantly updating and upgrading their capabilities and functionality in ways we didn't even know we needed until we …
Chose RingEX
From the user perspective, JustCall and Aircall gave you the ability to listen to the recorded call. RingEX's taking notes feature is great, just not 100% accurate. Therefore, I would say having the ability to access the recording calls in the user interface can be very useful. …
Chose RingEX
RingEx is more user friendly and the reporting is also one of the reasons we chose it. Voi is also a great tool we use and is very user friendly.
Chose RingEX
RingEX's Reliability and overall cost helped with our decision. While the competition have corresponding products and features, RingEX seem to really nail it in terms of usability.
Chose RingEX
In my experience, Ring Central is hands down a better platform than the other VoiP companies I have used. Clear calls, functionality, level of fine tuning, that other companies do not have, is appreciated.
Chose RingEX
Many of the features are the same but I feel that RC makes it more user friendly for configuration and work. We have also not seen the cost increases with RingCentral that we saw with the other providers

Chose RingEX
RingCentral's flexibility and reliability proved to be far superior to the other products we tested.
Chose RingEX
Vonage was setup more so by extension, than user. RingEx app is far superior with the ability to send messages to other team members. Voice recording with vonage was not ideal. It was hard to navigate call recordings, and there was no ability to clear calls after so long of …
Sprinklr Service
Chose Sprinklr Service
We briefly used Hootsuite with another client. From day one, there were issues, from logging in to trying to compile data. We very quickly switched from that to Sprinklr.
Chose Sprinklr Service
Very similar in promptness, politeness and skill. Availability on weekends is good for both.
Chose Sprinklr Service
First, we had a social studio which was good in terms of functionalities but slow. After that, we had the chance to use Talkwalker & social bakers which were good tools yet not enough compares to Sprinklr
Chose Sprinklr Service
The tool is the best compared to the competition. It has advanced features. It is more difficult to master the operation, but in the long run, it is beneficial.
Chose Sprinklr Service
Many tools are the same, but the one where I noticed the biggest difference was between brandwatch and Sprinklr when it comes to social listening. Brand watch has a good and more affordable social listening platform, but it is not as easy to use and requires the client to code …
Chose Sprinklr Service
We also use Meltwater in our BU, and the good thing about Sprinklr is that you can actually compare your data numbers with the key word searches. Meltwater is limited in that it doesn't offer a wide range of services. Although the graphs and some other analysis functions on …
Chose Sprinklr Service
These tools were good to manage social interaction when you just have one or maybe two social media managers who take care of anything. When it comes to teams, there was not a good way to manage bigger amounts of requests and to have an overview of who does what. So you waste …
Chose Sprinklr Service
Sprinklr Modern Care is a stand out platform compared to previous social tools I've used. The listening tools are fantastic and unlimited.
Chose Sprinklr Service
Easy to use/user-friendly is the first benefit that comes to mind. It's very intuitive and doesn't require any training to get up and running and to start seeing the benefits.
Chose Sprinklr Service
The social listening and benchmarking dashboards of Sprinklr Modern Research have been a huge game changer for our department. They allow us to gauge the competitive landscape and monitor any trending topics in a particular space which allows us to realign our priorities for …
Chose Sprinklr Service
I only use this solution
Chose Sprinklr Service
We previously used Sparkcentral for our social media care. While we were very happy with the team there, the product had not evolved as much as Sprinklr and we found it to be lacking in its ability to handle different languages, route certain types of conversations with higher …
Chose Sprinklr Service
I've never used any Sprinklr Modern Care alternatives, but when it comes to communicating directly with customers, I much prefer using Sprinklr Modern Care over contact form and email interaction.
Chose Sprinklr Service
Prior to Sprinklr Modern Care, we used vBulletin and a custom repository to address the community needs of our customers. Keeping the experience user friendly was a key point on our needs list and our custom solutions and vBulletin forums were only positive experiences for our …
Chose Sprinklr Service
Evaluated and considered tools like uservoice, Lithium, Jive, and SuggestionBox. Ultimately, being able to quickly provision the system and test drive things in real-world situations really influenced the decision.
Chose Sprinklr Service
Uservoice.

We really liked the way that the Sprinklr Modern Care technology worked. It was really simple, easy for customers. Ultimately the technologies are not that different. The bigger reason is that we really appreciated the team at Sprinklr Modern Care.
Chose Sprinklr Service
• We use a tool called HelpSpot for email ticketing. They have a knowledge base for FAQs but no forum / community platform. Their technology not nearly as good • We looked at a number of tools that did either FAQ or feedback or community, but none except Sprinklr Modern Care …

Kamailio SIP Server is very well suited if you want to secure your main servers; it can perfectly act as a proxy server and a gateway to your main server. It also does load balancing and call transfers easily based on the configurations done.

RingCentral is generally good for business calls, as its mobile features, combined with landline office options, are great for communication on the go. It is also an affordable option to have a mobile cellular device if you have a lot of staff. Setup especially for multilevel authorization can be a hassle but it works well if well set up, you would have to get help in rectifying this if not calls might be redirected to the wrong extensions and changing it is not very straight forward.

Sprinklr Service has always been well-suited for all of the work we do. As it's all social media content, and most require responses or escalations, Sprinklr Service covers all of that. The only time I think we wouldn't need it is if we were working with a much smaller client who didn't need us to have eyes on so many platforms at once.

Pros
  • Proxy server.
  • Security Firewall.
  • SIP to PSTN gateway.
Read full review
  • Chat and Messaging - Conversations are easy to search, topics can be pinned or bookmarked, and groups are easy to create and administer.
  • Phone - The core functionality works very well allowing voice, txt/sms, and faxing for all users. Administration is generally fairly easy as well.
  • Mobile Client - the mobile app offers all of the same functionality as the desktop or web client.
  • Video - Video calls make it easy to share screens with other users and includes a lot of tools for planning.

  • Transparency—Sprinklr Modern Care allows us to engage with our customers openly and honestly. Even frustrated or angry customer posts offer an avenue for us to display our business integrity and turn negative experiences into positive ones.
  • Moderation—Being able to moderate and organize our community so easily by merging topics into one canonical thread or archiving out of date threads helps to keep our search results relevant and improves the chances that our visitors find the help they need easily.
  • Company Visibility—The ability to easily alert any company employee of topics that might be interesting to them helps to improve the overall visibility of our customers. It also makes it easier to spot trends and encourage quick action if many people comment on one topic with the same problem.

  • We can use the RingEx in our Mobile to use for Basic calls and messages, but sometimes the mobile application lags or disconnects while using video calls or screen sharing.
  • we can easily configure in our laptops.
  • The Meeting recording option is really helpful for our organization

  • I find it difficult to dive into analytics for each social post. The reporting tool gives me an overview of the channels but I would love to look at a breakdown of each post performance.
  • You currently can't add closed caption subtitles to videos uploaded through Sprinklr so this results in having to revert to the native platform.
  • I would love to be able to set up a newsfeed that includes posts from a number of our partner accounts, so I can keep up to date with what they're posting.

We switched to RingEX for ease of administration, flexibility of integration (fax, web meetings, chat client, mobile app) and competitive price. Although the system has had a few quirks as it's been relying on our network much more heavily and integrating with our next-gen firewall, I can't speak highly enough of what RingEX has done for our business. I love it and can't wait to renew for a longer period of time at an even more competitive rate.

The initial use of the product started out as a 90 day test to see if we could engage customers at a higher level using Sprinklr Modern Care. After a year the use of Sprinklr Modern Caren has now been extended to multiple products.

Usability
No answers on this topic
Once you get used to the features of the system, it is extremely easy to find what you need. Everything is all on one place which makes the usability phenomenal. It is very user-friendly, and everything you need is mainly on the RC app. There is a separate window for your Max Agent, and everything is spelled out so you rarely have a question where something is.
Read full review
It's a very easy program to learn and use. I have trained over 50 people on it over the years, and not once has anyone had trouble using it. It's very user-friendly and covers all the bases that social media moderation requires.

Reliability and Availability
No answers on this topic
There have been outages in the past, but they keep you updated on their status page. They instantly start working to resolve the issue in a timely manner. The reporting is clearly laid out if your area is impacted. They ensure that they email any updates they've made to the portal or any products they offer.

No issues with system availability. They manage updates in off-peak hours and I usually don't notice the changes until I log into the system the next day.

Call-in support is fantastic. I have never called in and had it taken more than 30 minutes to resolve our issue. Email support is terrible. You will likely go 24+ hours until you hear back and the response is likely a canned one. I personally prefer the email or chat support option, but find myself calling instead because the email support experience is so poor.

I know the Sprinklr conference calls have been helpful, but sometimes submitting a ticket can be a little daunting. In the past, we've included information in screenshots that are then asked for by a member of the support staff. The turnaround time has been between 3 days, which isn't horrible.

If someone has an existing system I tell them to keep that running initially and keep RingEX separate initially until the system is configured and tested to one's satisfaction. After testing and configuration is completed, then roll over the main phone numbers to the new RingEX system. I've seen one person who immediately flipped over to RingEX without properly configuring/testing the software and had many issues with missed customer calls until I helped him sort out his configuration.

Basic setup took me less than 30 minutes. This includes initial configuration, putting in the initial content, and getting the look-and-feel customized. The domain routing took the normal lag time any other website or blogging service. The really important thing was to get the user accounts setup and begin seeding the system with content before a public launch.

While aircall can be very similar to RingEX, RingEX is easier to use on the web version, desktop app or mobile app, makes search easier and has the ability to provide the transcribe. Then, Convoso is more oriented to outbound sales calls so it's hard to get in touch with a specific person since only has one main number assigned and the incoming call can be transfer to a person who might not be aware of the reason of the call, which causes a delay for the caller to get on hold with the right person

While we were very happy with the team there, the product had not evolved as much as Sprinklr and we found it to be lacking in its ability to handle different languages, route certain types of conversations with higher priority or to certain teams / agents.

We have 75 users and 85 phones on the system and have yet to have any noticeable outages. The system just works all of the time without issues. Our old VOIP system on Voyant would go out all the time for multiple hours. RingEX is much more stable and reliable.

Return on Investment
  • As its open source ROI is excellent.
Read full review
  • The ability to text vendors via RingEX has enabled us to schedule meetings, which has led to things getting done.
  • Since the app works as a secondary phone, it supports privacy, and allowing messaging enables HR and LC to contact people, ensuring they are heard and their needs are met.
  • The calling feature has enabled the company to make important calls to vendors and others when needed. Allowing for contracts and many other things to get done.
Read full review
  • Increased employee efficiency: Having a clear, one-stop "shop" where users can leave feedback, ask questions, and find bug fixes or workarounds has saved me (and other community managers at my company) loads of time that was once spent responding to numerous emails on an individual basis.
  • Better customer service: Since everyone in the company is alerted of what's being written on our forum, it's easy to spot a high-priority issue, delegate to the person in charge, resolve it, and respond as soon as possible.
