|
- This module aims to implement several sanity checks on incoming
|
|
|
|
- requests which are suggested or even required by a RFC, but are
|
|
|
|
- not available yet in the core of &kamailio;.
|
|
|
|
- </para>
|
|
|
|
- <para>
|
|
|
|
- These checks are not required by &kamailio; itself for its functionality.
|
|
|
|
- But on the other side it makes not much sence if a broken
|
|
|
|
- request traverses through a SIP network if it is rejected sooner
|
|
|
|
- or later by a SIP device any way. As every sanity check cost extra
|
|
|
|
- performance because of additional parsing and evaluation it
|
|
|
|
- is with this module now up to the &kamailio; adminstrator which checks
|
|
|
|
- should be done on which request.
|
