[Freeswitch-users] DTMF filter (RFC2833)

[Christopher Rienzo]

I don't think this exists in FS.  You can create a small dialplan APP that
installs a DTMF hook and drops all digits that aren't 0-9,#,* by returning
SWITCH_STATUS_FALSE to drop and SWITCH_STATUS_SUCCESS to allow.
 mod_dptools.c and switch_ivr_async.c have examples of DTMF hooks.
