[Freeswitch-users] Can I use the dialplan to execute specific tasks after an incoming all has been bridged?

I wish to do some variable bookkeeping and database manipulation after an incoming call has been bridged - but before hangup. If possible, I would prefer to keep the dialplan lean and not to use the javascript application, but I havn't figured out how. In terms of Asterisk, I would like to emulate the dial M(macroname) option. What are the options for doing that? And are there special consideration with respect to accessing channel-A vs. channel-B variables?
