View source for SIP NAP Polling

== Polling ==
* In Tmedia, option [[Parameter:_Poll_Remote_Proxy|"Poll Remote Proxy?"]] is enabled by default
* Tmedia SIP polling is using SIP OPTIONS method to "poke" a SIP [[NAP|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 [[Parameter:_Map_any_Response_to_Available_Status|"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
** 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)

== [[NAP|Network Access Point (NAP)]] Availability ==
If [[Parameter:_Poll_Remote_Proxy|"Poll Remote Proxy?"]] and [[Parameter:_Register_to_Proxy|"Register to Proxy?"]] are both checked, only the SIP OPTIONS answers will affect the [[NAP]] availability.
