If you happen to have a polycom or snom and you use the new sched_api  
extension I added to trunk (commented out) it will sched_api and snag  
the zrtp sas1 and sas2 strings and 4 seconds after the call is up  
update the display of the polycom with those two strings... kinda  
handy eh?

For those not wanting to go hunting for it.

<action application="set" data="exec_after_bridge_app=${sched_api(+4  
zrtp expand uuid_display ${uuid} \${uuid_getvar(\${uuid_getvar(${uuid}  
signal_bond)} zrtp_sas1_string )}  \${uuid_getvar(\${uuid_getvar($ 
{uuid} signal_bond)} zrtp_sas2_string )} )}"/>

:P  Try that out!
