Hey Brian,

Will have a look at ZRTP :)

Not sure I understand your comments regarding its all over once
receiving the 415 from the B party.  Is'nt that what parm
continue_on_fail does?  The fact that it sends the invite back out
sorta proves this.

The A-LEG has to hangup to re-enable SRTP it can't do it if it didn't invite with it in the first place.


The other point of interest here is that if you set <action
application="export" data="sip_secure_media=true"/> before the first
bridge function it will include the security descriptions in the B leg
INVITE even when the A leg does not have them and the call will
succeed.  The B Eyebeam will show the locked padlock while A does not.

Make sure you do not answer the call before you do it.


From what I can see in code it is this guy that must stop it all from
happening.  TFLAG_SECURE  But I dont understand why :(

Again you have to invite to FS with crypto it can't magically cause crypto to work unless you initiate it with your first invite.


Regards,
Jim
