    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.

    Suited if you want to hear old calls. Not suited for teaching new SDR's how to talk or what a good call is and why. Kixie doesn't transcribe either.

    I find it to be the best resource for scheduling calls with clients. Specifically when the call includes multiple people using Salesloft, it's so simple and easy to use to send open times to client and then to be able to send active links to the client where with one click the calendar invite shows up on my calendar? it's the best most efficient tool I have in my toolbelt at the moment. When it comes to logging, it's also simple but I wish I could add a contact to SL from the Microsoft integration.

    • Kixie integrates seamlessly with our CRM (Zoho), meaning it updates call notes directly on the customer's CRM profile.
    • The one-click dialing feature directly through our CRM is a great feature. It's so simple; just search for a name, one-click, and you are on the phone.
    • The local presence feature is a nice touch for cold calls. It provides a local area code when cold calling to increase the likelihood of an answer to the call.

    • User interface, sometimes the list you are calling on the tool can glitch and not show you the info of the lead.
    • Integration with more CRMs like Agencyzoom
    • An email automation option similar to text messages.

    • Would be nice to have custom reporting available. Coming from Salesforce, the included canned reports are useful but I like to roll my sleeves up and build exactly what I want.
    • Conversations will record meetings booked via MSTeams but requires the BDR/SDR to hit record. Other solutions (e.g. Chorus.ai) join as a participant and don't require a user hitting the "record" button. We have to change our flow to make this work and it is a bit clunky.

    SalesLoft is absolutely VITAL to our daily operations. We could not function without it or a program like it. Speaking as a Sales Person who has had to operate without a product like this, the difference is night and day. The ability to stay organized, automate tasks, easily log activities and notes, review calls, and coach team members is an absolute gamechanger.

    Kixie provides a nice user interface. There is a bit of a learning curve to load leads but it's not difficult. It's just learning where to go and how to load lists for the reps. Once you have it figured out, it's easy to get lists loaded for reps and give them the ability to manage those leads

    Drift was extremely easy for both our demand gen team and SDR to jump right into. It was feature rich and purpose-built for marketers—it was remarkably easy to connect our marketing automation, CRM, and more to the platform and get everything to work together. Now the ability to create digital experiences and conversation landing pages is democratized—empowering our team to do better work and provide better prospect/customer experience.

    The availability is pretty good, we do sometimes have errors or delays in syncing activities but nothing that has been too detrimental to our workflow. Most recently we had an issue with Lofting through Outlook due to a change in security token that took a few weeks to resolve but it is fixed now.

    Yes timely and easy to use. The only delays we have are when we run our big month sales blitz and activities take some time to sync to the reporting as well as SalesForce

    The support team was very responsive but at the end of the day they took a long time to fix our issue. The issue did get fixed, though, so that is what matters. Very nice people who are there to help in any way they can.

    We had some virtual training with our CSM which was very well constructed. It took some time to get into the full swing of things but with a few weeks of hands on experience I was feeling confidant. The SL team was always available to answer questions or jump an a call to walk us through stuff. I also used the Customer Help Center for a few self guided learnings on how to use specific features related to reporting and team management.

    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 SIP Server. And one server is enough to handle thousands of calls simultaneously.

    Salesloft blows outreach out of the water in all aspects. One of the biggest issues I had was their unwillingness to listen to customer feedback. I had requested several small changes to be made when I had previously used the platform that unfortunately fell onto deff ears. I am much happier using Salesloft and the positive results I've experienced are a direct result of that.

    • Kixie's dialer allows us to dial directly from our CRM
    • The voicemail drop feature saves time and allows our BDRs to move on to the next call right away
    • The automatic log calling saves even more time instead of having to log the call manually

    • I have been with a company that was using Salesloft, but moved to a competitor. I can't say it was exactly the competitors fault, as a lot of other internal changes were happening, (hence leaving the system that was working well), but we had the worst sales year in company history that year. Reps who consistently performed at or above quota were suddenly struggling to keep their pipelines in order, and the middle of the pack reps were going on PiPs and being let go.
    • Is it the dialer, or the leadership? You decide.
    • But the leadership also changed the dialer - so maybe it's both?
