SIP NAP Polling
Polling
- In Tmedia, option "Poll Remote Proxy?" is enabled by default
- Tmedia SIP polling is using SIP OPTIONS method to "poke" a SIP Network Access Point (NAP) to see if it's alive or not, that is, NAP availability
- Upon a response from the SIP NAP, Tmedia will determine whether to mark the NAP as up
- If the option "Map any response to available status" is unchecked, only a 200 OK to a SIP OPTIONS will bring the NAP up
- The first time a SIP NAP is added in configuration and configuration activated, Tmedia polls at 5 seconds, after that and general use is polling at 60 seconds
Network Access Point (NAP) Availability
If "Poll Remote Proxy?" and "Register to Proxy?" are both checked, only the SIP OPTIONS answers will affect the NAP availability.
