    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.

    • 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.

    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

    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.

    Good for the price and Pipedrive integration. In my opinion, less relaible than others

    • 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
