It's not exposed to configuration, but the stack does allow for this.  Would require code changes.

Hi all,
 
I am looking for a way to disable certain SIP methods like „MESSAGE“ for example.
Is it possible to configure FS to ignore methods or send a 405 method not allowed?
 
Currently I run iptables  to block methods (like MESSAGE).
We plan to implement TLS + SRTP, but that would not work with iptables anymore.
 
Can you help me out here?
 
Thanks in advance!
