[Freeswitch-users] piped failover doesn't work in dialplan, but works from console

The ^^: make it do

QUOTED_ESC_COMMA

vs

UNQUOTED_ESC_COMMA

Which will make it do this later in the code:


                    for (p = chan_type + 1; p && p < bend && *p; p++) {



                        if (*p == QUOTED_ESC_COMMA) {



                            *p = ',';



                        }



                    }

I've had both cases work for me in testing.
