Summary:                    [regression] app_sms not working in 1.6.1.12 (same
as 0012779)
Description: 
app_sms has reverted to the same issue as in entry 12779:-

chan_dahdi.c:     -- Requested transfer capability: 0x00 - SPEECH
app_dial.c:     -- Called g1/17094009
app_dial.c:     -- DAHDI/2-1 is proceeding passing it to
Local/17094009 at default-549e;2
app_dial.c:     -- DAHDI/2-1 is ringing
app_dial.c:     -- DAHDI/2-1 answered Local/17094009 at default-549e;2
pbx.c:        > Channel Local/17094009 at default-549e;1 was answered.
pbx.c:        > Launching SMS(1268466100) on
Local/17094009 at default-549e;1
app_sms.c:  sms argc 1 queue <1268466100> opts <> addr <> body <>
app_sms.c:  initial delay 300ms
pbx.c:   == Spawn extension (default, 17094009, 1) exited non-zero on
'Local/17094009 at default-549e;2'
app_sms.c:     -- SMS RX 93 00 6D
app_sms.c:     -- SMS TX 17 00
chan_dahdi.c:     -- Channel 0/2, span 1 got hangup request, cause 16
app_sms.c: ast_read failed
chan_dahdi.c:     -- Hungup 'DAHDI/2-1'

The messages never get sent (this is an upgrade from a 1.4 version of
asterisk which had no issues with the sms application).

---------------------------------------------------------------------- 
Have tried 100 and 150 with no difference, also 400 and 500 likewise.

Have tried compiling with alaw and the code doesn't compile, haven't
investigated why.

Looking at the trace it does see two way traffic so the number is dialled
and picked up, the response is fairly standard so not just noise.

The duration from last received data to hangup is 3 seconds (just looked
at the 10 attempts I've made today and it's the same on all of them).

At a guess (and a pure guess), the remote end doesn't understand our FSK
transmission?
