[Freeswitch-users] generate deliberate packet loss?

Hi All, I would like to make a sip call through my freeswitch server to a device registered onsip and cause packet loss on either side of the call (not simultaneously, though). Is something I would be able to do through fs_cli? I know a little bit about the uuid_jitterbuffer, but that seems to cause delays with all the packets eventually arriving. Thanks!
