DTMF not working while connected to WLAN

[GoogleCodeExporter]

DTMF not working while connected to WLAN, but working fine while connected to 
3G/EDGE

I connect through pbxes.org. Initially I could not get DTMF to work and I 
tried all settings available in pbxes.org.  I thought it was a problem with 
my service provider (VOOOVOX).  However, I always connected through WLAN and 
then realized that DTMF works in 3G/EDGE once I tried that connection.

Using freephonie.net with Wifi, it doesn't work either (cannot test on 3G/edge :
crappy gateway/proxy)

I am having same problem. When i have tried to call from sipdroid to my Bank
customer-care number then DTMF tone didn't work. Not even single digit is 
detected at
sip-server. Like choose your language....etc.

The priority of this bug should be set to "High".  It makes sipdroid useless as 
a
phone replacement.

With version 25 (not sure what version string that corresponds to) DTMF tone 
works
while accessing my regular t-mobile voicemail. Upgrading to 1.1.1, DTMF tone no
longer working. Not sure if the upgrade broke anything. I'm on WLAN as well. 

Using a softphone (X-lite) on my PC with the same setup works perfectly fine, 
so the
problem is likely from sipdroid...

Same issue here, no IVR can be worked with SIPDroid.

Please, can you tell me if the call status is "connected" or "dialing"? There 
is no
DTMF available during the "dialing" status.

My problem with DTMFS is if I send them slowly, then - all went correct,if I am 
sending fast - pressing digits before end of tone, then there are mnissing 
DTMFs.
Using aSIP - all DTMFs are correct speed doesnt matter.
Platform: HTC Desire, android 2.1 (rooted) - sip droid 1.4.7 (beta).
aSIP - 1.2.4 beta sipdroid.....
Account is to Asterisk 1.4.21.2 - connection WiFi or 3G.

Using the latest sipdroid 1.4.7, using pbxes.org account, DTMF does not work in 
any 
context.  I can't enter my VM password or navigate any DTMF menus.

When I change absolutely nothing, and use x-lite softphone to connect to 
pbxes.org 
DTMF is sent perfectly.

This confirms that the problem indeed lies with sipdroid.  DTMF does not work 
over 
3g or wifi with sipdroid, but works perfectly with x-lite with absolutely no 
changes 
made to account at pbxes.com

Sipdroid needs to have an option to select DTMF type, such as RFC2833

I use aSip 1.2.4 with a Gizmo5 account, Google Voice account, and GVoice 
Callback
feature and can not get the touch tones to work either.  I am currently running 
on my
G1: HTCClays Superbad 1.4.1 (Eclair 2.1 Rom) and 2.22.23.02 Radio (lots more 
extras
too) if that makes any difference. I am running everything WiFi currently (no 
sim
card in the phone right now)..... If this is going to be a phone replacement, 
this is
something that definitely needs to be fixed ASAP

Sipdroid 1.5.1 on Nexus One (AT&T) through Wifi only all the time and almost 
all DTMF-based calls to most customer support 1-800 numbers don't work. Using 
my Google Voice number with Gizmo5 SIP account registered on PBXes.org. I also 
tried to use the PBXes.org's call transfer feature (requiring pressing ##) and 
that doesn't work either. I think this issue should be marked high priority.

I have the same problem while a initiat a wifi call via ASTERISK. I can't send 
DTMF tone.

I tried sipdroid 1.5.2 beta on M70003 MID(300 Mhz via CPU).

Still does not work in 1.5.7.  Any updates?  This is kind of a big deal...

I am using a Droid (original) running 2.2.1 and DTMF does not work. I tried 
calling another phone nearby and pressing the numberpad and it seems that it is 
coming through as pulsed, rather than tone.  I am calling through the automatic 
Google Voice - PBxes setup.

Try this: don't check "use 3G" and don't check "use EDGE" only check "use Wifi"
Works fine on my Phone.

I'm experiencing this with sipdroid 2.3 beta on an acer iconia a500 with 
Honeycomb 3.1
The call quality is exceptional but I can't send any options from kepyad (dtmf 
tones) to my sipxecs server.
CSipSimple works fine - but call quality is poor compared to sipdroid

I also have problems with DTMF tones, it seems to repeat or break up. Perhaps 
there is an echo. The receiving IVR has problems interpreting the tones 
properly.

I'm having this issue with 2.3b on my Droid X. Have tried setting dtmf to 
"Info" on pbxes.org for both extension and trunk. Only have use Wifi 
checkmarked.

I was having this same issue but with mixed results depending on the conference 
number or voice mail I was calling.  The option that finally worked for me 
was... Sipdroid > Settings > PBXes Features > Simultaneous Outbound (enable).

I'm not sure exactly what this settings does, but DTMF tones are now working 
for me.

Version 2.4 beta | Google Voice over Wifi
