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, any 2xx/3xx/4xx class response 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
- Since version 3.0.73 NAP SIP MAP polling is configurable with two parameters:
  - Proxy Polling Interval (Default 1 minute)
  - Proxy Polling Response Timeout (Default 30 seconds)

If "Poll Remote Proxy?" and "Register to Proxy?" are both checked, only the SIP OPTIONS answers will affect the NAP availability.
