Zentrunk Now Supports SIP OPTIONS Pings

SIP OPTIONS pings are widely used in SIP communications networks as a health check mechanism. You can have your PBX issue SIP OPTIONS messages to a Zentrunk SIP trunk. Zentrunk will return an appropriate response that you can use to assess the health of your outbound trunk. This technique can help you avoid trying to set up a call to an unavailable SIP server, which could delay your outbound calls.

SIP OPTIONS pings are only supported on requests sent to an outbound trunk URI — not to trunk IP addresses. Please do not send more than one SIP OPTIONS message per 10-15 seconds to avoid your requests getting blocked.
