SIP Monitoring Over TLS and Websockets

We’ve added TLS and Websocket support to our SIP check.

NodePing has supported UDP and TCP SIP monitoring for many years but more SIP services are being offered over TLS or Websockets now so we’ve added support for these transports for your SIP checks.

SIP over TLS uses the popular SSL/TLS transport to secure the SIP communications. If your TLS is misconfigured or has an expired certificate, your SIP check will fail.

SIP over websockets are used mostly for browser-based SIP services. Your SIP check can also be configured to use secure websockets, which adds TLS security to the websocket SIP communication.

Monitoring SIP over TLS and monitoring SIP over websockets are both available on all accounts. If you don’t yet have a NodePing account, please sign up for our free, 15-day trial and see for yourself why those who know use NodePing.

SIP Monitoring

If you run SIP servers, you’ll be pleased as punch to know we’ve just released a new SIP server monitoring check just for you. Now you can be alerted if your SIP server goes offline or isn’t responding to SIP commands.

SIP stands for “Session Initiation Protocol,” and refers to a signaling protocol that can run over TCP or UDP and is commonly used for voice and video communications. SIP servers are often the connection points for VOIP calls.

The check does not initiate a call, but rather tests that the the server accepts a SIP connection by sending the OPTIONS command and watching for the response. Even if your server does not support the OPTIONS command and returns an error, this indicates that the server is up and operating, so the check succeeds. You can find more information about this check in our SIP Check documentation.

This new SIP check is available today for all NodePing accounts. If you don’t have a server monitoring account with NodePing yet, head on over and sign up for our free 15-day trial.
