Open Source
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.

Telnyx is well suited for general phone number provisioning as they have a large pool to choose from. There is certainly room to grow with fax troubleshooting.

  • Price Matters for the flourishing organization like us. Telnyx [is] affordable to us.
  • Telnyx is very generous in terms of providing regular updates through webinar , free credits, real time support . One most important is that they are not in hurry of closing the account because of minus balance.
  • Telnyx Portal is pretty easy to navigate and manage the customized settings.
  • Among other giant SIP providers I found Telnyx with very modern and humble customer approach.

Telnyx
  • Number testing: Currently I need to call our fax numbers manually to confirm fax tones. It would be useful to test numbers in bulk from the portal.
  • Troubleshooting: Currently, samples are needed for each fax transmission when there are issues. And those samples need to be within 24-48 hours. It would be useful if Telnyx could do a health check out proactively to gather information on high failure counts prior to customer reports.
  • Transparency with system issues: We've run into scenarios where we wanted information on system-wide fax failures, but when the issues were resolved we didn't get root cause analysis.

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.
