Well, I've tried reproducing this with various combinations of secure and insecure endpoints and cannot get it to fail.  Even the scenario you supplied the config for, where 225 doesn't have G722 but the first 2 do, works.

So, more info is needed....
The transport configurations for all transports involved.
The logs with...
{noformat}
core set debug 3 res_pjsip.so
core set debug 3 res_pjsip_session.so
core set debug 3 res_srtp.so
pjsip set logger on
{noformat}

> Call between two SRTP endpoints work ok until transferred to a device that does not have SRTP.  Then Asterisk logs:
> {panel}
> res_srtp.c: SRTP unprotect failed with: authentication failure 110
> {panel}
> Audio is lost from the call at this point.
