Robbed bit signalling only denotes the state of the call (i.e ringing or busy, etc) . I'd say you need an in-band DTMF detector for this to work. mod_spandsp already provides this functionality of what you're looking for. The same goes for the opposite when you are calling from SIP-> TDM (meaning you have to have a way to generate in-band DTMF tones from the RFC 2833 signals).

FS logs, FreeTDM Config and Wanpipe Config files might be helpful.

PS. I only did CAS on Sangoma -> Rhino CB24 with CAS, was not on FreeSwitch, but had to do some wanrouter config to set it up.

Are there any tricks to getting Robbed Bit Channel Associated Signaling (CAS) working properly with FS (legacy 1.06 nor latest git seem to show desired results) and Sangoma boards. I am using model A102, REV 1.1. DTMF does not seem to be recognized in the call stream so IVR does not respond. SIP calls work fine.
