CM currently uses h245 out of band signaling.  In the future it will support
rtp payload.

With 'out-of-band' selected, does your dtmf relay work?

CM and most Cisco IPT devices only work with DTMF out of band.
Does this setting have any other options?
DTMF over IP: in-band
----------------------------

FYI, it looks like the IP signalling group options on the S8700 for
DTMF over IP are 1) in-band; 2) in-band G.711; 3) out-of-band; and 4)
rtp payload.
