capture the output from api:execute the uuid is in there

because lua calls it freeswitch.bridge

session1 = freeswitch.Session("sofia/internal/1001%192.168.1.1");
session2 = freeswitch.Session("sofia/internal/1002%192.168.1.1", session1);
freeswitch.bridge(session1, session2);

The above is gibberish try:

local session1 = freeswitch.Session("sofia/internal/1001%192.168.1.1");
session1:execute("bridge", "sofia/internal/1002%192.168.1.1");
