Session Initiation Protocol (SIP) processing
For additional information on the SIP protocol see also :
https://en.wikipedia.org/wiki/Session_Initiation_Protocol
https://tools.ietf.org/html/rfc3261
Remark : RFC 3261 is the basic SIP RFC. Various extensions and clarifications have been published afterwards.
For the different SIP request methods an exclusive selection of always or on error or never can be made :
When
is selected then ALL SIP messages are shown in the output.
(INVITE, REGISTER, OPTIONS, SUBSCRIBE, NOTIFY, PUBLISH)
When
is selected then ALL ERRORNEOUS SIP messages of the specific request method
(INVITE, REGISTER, OPTIONS, ...) are shown in the output.
The on error selection can be used to focus on error cases inside (large) Wireshark files. This helps to improve the needed processing time as also the required disk space.
When
is selected then NO SIP messages of the specific request
method (INVITE, REGISTER, OPTIONS, ...) are shown in the output.
The never selection can be used to focus on specific SIP message types, e.g. to filter out SIP OPTIONS that can represent the majority of the SIP messages.
This selection helps to improve the needed processing time as also the required disk space.
The output of the SIP flags is explained in the section SIP messages .
