in your sip.cong [general] contexts
put
disallow=all
allow=ulaw
allow=alaw
and in your sip user, use disallow only ONCE, that is
disallow=all
allow=ulaw
allow=alaw
hope this helps.

Hi there,
I am writing to ask about how to fix the codec to G.711 ONLY.
Actually what I am doing is, try to use DTMF when the POTS phone call has
directed to Asterisk via Planet VIP-450 FXO Port, but this gateway just
simply doesn't support RFC2833 nor SIP-INFO. The only method I can use is
Inband DTMF. I know it only support G.711, but I DID disallow others and
make it work only with G.711. But the problem is, although I disallow all
other codecs, ilbc still itching me...
[extensions.conf]
[852]
username=HKGW
serect=blah
type=friend
host=dynamic
nat =yes
canreinvite=no
disallow=all
disallow=ilbc
allow=ulaw
dtmfmode=inband
(P.S. I don't use REINVITE simply because I need the asterisk to be a
media gateway cause the gateway is inside NAT behind the Asterisk)
Whenever I try to pass DTMF from phone to Asterisk via that gateway, I got
such messages:
Dec 14 23:35:32 WARNING[10958]: dsp.c:1422 ast_dsp_process: Inband DTMF is
not supported on codec ilbc. Use RFC2833
Dec 14 23:35:32 WARNING[10958]: codec_ilbc.c:175 ilbctolin_framein: Huh?
An ilbc frame that isn't a multiple of 50 bytes long from RTP (4)?
How come!? I DID DISALLOW them, but it keeps bugging me....

Previously I installed 1.0.3 in same machine, but I overwrite all files
with 1.2.1.. does it cause a trouble?
Can anyone figure out what is the problem?
