Subject: GSM MNCC: Make sure to set the MNCC_F_KEYPAD when ACKing DTMF
X-Git-Url: http://git.eversberg.eu/gitweb.cgi?p=lcr.git;a=commitdiff_plain;h=998bb9ca7dee3c7ce3028af1f26a7d389d867cd4

GSM MNCC: Make sure to set the MNCC_F_KEYPAD when ACKing DTMF

TS 04.08 has a _mandatory_ KEYPAD FACILITY IE, and unless we set
the MNCC_F_KEYPAD, some phones will (legitimately) reject the
04.08 DTMF KEYPAD_ACK without that IE.
