Open Source
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.

CallHub
  • For all calls, you must complete at least the first question you are asked in the survey so that we know what type of connection.
  • You can leave a voice message, and a pre-recorded message will play on your answering machine or service when the call is saved.
  • If you get a signal compromised or problem you can hang up once you are in the software which makes it quick and easy.
