If RBS means robbed bit signalling then it is transmitted in the media bit
stream but as the name implies it is not used for media. If I remember
correctly the LSB from every sixth

I messed up. The E lead receives signalling whereas the M lead is used to send
to the far end.

Is there support in FreeSWITCH for MF?
To answer my own question ...
Perhaps I can add a ZAP_COMMAND_SEND_MF case to zap_channel_command
patterned after ZAP_COMMAND_SEND_DTMF and just use teletone_set_tone
to set the proper frequencies???

Isn't RBS more than just MF? Unless I'm forgetting something you rob
a bit.

I happen to have both a line side and a trunk side T1 card for my NEC
2400 PBX. I've done this sort of thing with asterisk and it worked
pretty well. Please let me know when you are ready for someone to do
some testing.

Steve,
As usual you are awesome! Is there anything the RBS users can do to
grease the wheels? Maybe we can do a reasonable bounty

Okay, I have a T1 up and running
Just curious as to the state of / plan for T1 RBS support.
Our System 25 PBX doesn't support ISDN, however it does support
RBS. It would be nice to be able to run more lines into our
FreeSWITCH box using a T1 instead of analog lines.
