[Asterisk-Users] FireFly Problems

[Paul Rodan]

Ok. For [user_test] I specifically disabled all codecs and ONLY allowed
Ulaw. This seems to have forced firefly into using Ulaw, regardless of
what's checked in the program.  

 

Also, I left dtmfmode as rfc2833 in sip.conf as well as set rfc2833 in
FireFly, and it appears to work. I didn't think rfc2833 could be used on
ULaw, but then again I know little about dtmf, my general rule was "Inband
for Ulaw, RFC2833 for everything else, and stay away from info as I have no
idea what it does"  

 

Also, I had to do "qualify=no" as FireFly apparently doesn't respond right,
I keep seeing "Unreachable" in the "sip show peers" commands for my firefly
clients, even though they can place and receive calls just fine. I just did
qualify=no and now it just says "Unmonitored" or something.  This may be a
bug, I saw the "poke" thing was fixed in IAX, maybe they accidentally broke
it in SIP?

How come FireFly doesn't give me an Inband DTMF option? Only RFC2833 and
Info. RFC2833 is the default, so I left it that way. I also unchecked all
the codecs except g711ulaw to force that codecs usage. However, when I go to
place a call, I get this:

 

Nov  3 13:18:44 WARNING[53641241]: dsp.c:1468 ast_dsp_process: Inband DTMF
is not supported on codec G.711 u-law. Use RFC2833

Nov  3 13:18:44 WARNING[53641241]: dsp.c:1468 ast_dsp_process: Inband DTMF
is not supported on codec G.711 u-law. Use RFC2833

 

 

That's funny, I thought Inband DTMF was ONLY supported on G.711 u-law

 

So in the sip.conf file, for the hell of it, I changed dtmfmode to rfc2833
and then placed a call with FireFly. This time the error didn't show,
however, I noticed that the GSM codec was being used, as could be heard and
seen with "sips how channels". I have GSM unchecked in FireFly, and yet it
chose it anyways.

 

In my [general] section of sip.conf

disallow=all                    ; First we Deny Everything

allow = ulaw                    ; Then we set our preferred codec

allow = gsm                     ; Then our backup codec

allow = g729                    ; And our last resort codec

 

 

and my account entry used to be:

 

[user_test]

context=user_testing

type=friend

username=user_test

secret=hidden

qualify=yes

host=dynamic

canreinvite=no

dtmfmode=inband

nat=yes

mailbox=1012 at home_users

callerid="Test" <1234567890>

accountcode=1

amaflags=omit

 

but dtmfmode=rfc2833 now.
