[Freeswitch-users] SRTP-Support

[Alois Komenda]

Hello,

I get this error when starting FS with TLS enabled:

2008-01-16 10:32:41 [DEBUG] sofia.c:464 sofia_profile_thread_run() Set params for default
2008-01-16 10:32:41 [DEBUG] sofia.c:486 sofia_profile_thread_run() activated db for default
2008-01-16 10:32:41 [DEBUG] sofia.c:516 sofia_profile_thread_run() Starting thread for default
nta: bind(192.168.0.21:5061;transport=tls): Protocol not supported
nua: initializing SIP stack failed
2008-01-16 10:32:41 [ERR] sofia.c:434 sofia_profile_thread_run() Error Creating SIP UA for profile: 192.168.0.21

I tried with transport=tcp and without any transport setting. The result is always this error message (with the respective protocol).

What's wrong here?

Their has been a script added to SVN for this purpose its gentls_cert in scripts.  And should allow you to create your CA and various files required for sofia's TLS ... BTW TCP is required on all SIP ua's no matter if its TLS or not.  Anything that doesn't do TCP is violating the spec because it says TCP and UDP are a MUST.  ;)
