Dtmf/CO2 DSL - VoIP General, VoIP News, VoIP Providers, VoIP hardware, VoIP software, VoIP Technology

Hello,

I have unfortunately most violent problems of Callthrough on my CO2 DSL connection for running to get. The Callthrough functions, but the evaluation of the DTMF signals makes difficulties. In 9 from 10 cases is it like that that numbers will transfer doubly. Thus e.g. becomes. out

0179 1234567 -> 01179 1234567 or 00179 1234567 or also 0179 112344567

If I call myself, I hear some numbers really doubly, although I press to definitely only once.

I have already everything possible tried out among other things all DTMF attitudes, loss-free Komprierungen etc.
The problem does not lie probably in the Fritz box. If I call the box over an Sipgate account, everything functions perfectly.

Does someone have ne idea?? Or there perhaps does intention put behind?

Observe selbiges now also for some time. CT pointed ran before, now lands additional DTM numbers doubly and the Anruf/CT lands in the Nirvana.

Use however not DTMF box but the internal CT the Fritz

EDIT: Do you have times with the abbreviated dialing try the problem to minimize? Thus a number in the Tel. book the Fritz and then with office e.g. **701
Functions so far, unfortunate that #31# for indicating the call number there not functioned

That is called some time ago went that times problem-free? Interesting.
In rare cases a number arrives also up to ten times or so, only so at the edge.

I use both dtmfbox and the internal CT, with both the same problem.

With the abbreviated dialing the problem can naturally out-lever a little. With dtmfbox I changed the CT-script in such a way that me the number is announced, so that I can break the call off. Next I plan to insert still another confirmation inquiry. That can however actually be also only a Workaround.

I already different codecs out tried. Unfortunately sip.o2online.de accepts only G.711. Nichtmal G.711u functions.

Are momentarily a little helpless, as one gets more reliably.

Hello camouflage cap

Question:
You call the Fritz from your mobile phone! Box on
You have the Family & Office option

If

You could attach gateway to the similar office entrance of the FB a GSM.
And of the mobile phone the Sim map in the gateway calls (dependent on your tariffs even free of charge)

Sagem RL xxx gives it quite favorably.

Greeting Resool

@ camouflage cap: did you activate fastpath? and with dtmf rtp and inband?

That would be indeed also an alternative. A RL 302 is even present. I would have to procure myself or tinker however first times a Y-cable.
However from it the language quality suffers somewhat. Before I had the RL302 with the FB 7050 in the employment and on the detailed line a humming loop, which could not be prevented, also not by grounding. Times see, perhaps start I again an attempt with the 7270.

@ camouflage cap: did you activate fastpath? and with dtmf rtp and inband?

It does not have effects whether I in the Fritz box FastPath or Interleaved activates. I did not book the SpeedPing option. The line is switched with relatively low Interleave depth and it is a very good line:

Code:

Empfangsrichtung 	Transmission direction
 max. one. DSL to data rate 	kBit/s 	17728 	1152
 min. DSL to data rate 	kBit/s 	128 	64
 interconnect capacitance 	kBit/s 	17224 	1114
 current data rate 	kBit/s 	15004 	1114
  			
Latency 		6 ms 	5 ms
 Bitswap 		on 	at
 Seamless rate adaptation 		out 	from
 impulse Noise Protection 		1.0 	1,0
 L2 power mode 	WELL 	- 	-
  			
Signal/signal-to-noise ratio 	railways 	11 	9
 line loss 	railways 	15 	9
 power-CUT-bake 	railways 	0

The DTMF attitude is with all accounts “RTP and Inband”

@ camouflage cap: me times called and see there: if I in the discussion grope presses and one hears completely clearly, like this MFV tones not properly and/or. to be transferred partly several times. Also the language quality is substantially better, not chopped off or stockig under load with Sipgate. Property no 2. PVC, ToS Sip 32 RTP 40

Property no 2. PVC, ToS Sip 32 RTP 40

Also the 2. PVC was not already tested to help, everything. I think it am a software problem in the Voip server with CO2. It suggests also that it suddenly began sometime.

Straight one times again tried, seems to have fixed. No Hoppler or misfires. RUL/CT function again reliably.

Thus with me nix changed. The numbers arrive partial always still twice or more frequently.

TC, after I times again started the FB, folds it now suddenly also with me with the DTMF signals. If that a technician here read and thereupon should have repaired, thank you!

Thus I have here unfortunately the problems still (despite restart etc.).

Sometimes those is transferred still correctly pin, but at the latest if I enter a call number, ' s gives errors….

Hello,
since then I changed the DTMF attitude to “automatically” go it over perfectly.

Where one finds this attitude. With me (L.G.,79, thus the original of CO2) nothing found.

Expert opinion activates

Thanks habs found. I had looked for only with the “global” Telefonie attitudes, not with the individual numbers directly.

1. Test with “automatically” was successful:>

with the problem have I also since the new firmware,80 to fight thanks for the tip

. In the meantime Mach I however differently. Fast and more comfortably at least on Android mobile phones. Owing to Sipdroid and Pbxes is that fast configures.

if I place with my 7150 on automatic, can I mean direct-inward dialing to forget. but with dtmf lufts? or an update did not get my 7150 correctly.

I have also since approx. two months the same problem. Dtmf of tones was actually sent partly 5 times repeated where to one. Both in my FBF 7270 and in the behind it-switched old Fritz box.

After I saw the contributions here in the forum, I switched to “automatically”. Unfortunately without success.

Have still more people the same problem? Does CO2 try to dam callthrough? Or are there any attitudes to the FBF, which one must make?

Greetings

Probably, last time geht's with me also not always, all the same which is adjusted, and which firmware version plays thereby also no role

Do not understand which that is, finally gives it Telefonkonferenzen where one compelling-proves dtmf sounds needs and there is sowas already rather nervig. Since it ran very reliably times, Mach I times a disturbance ticket up. Property already times called however of the normal Hotline up to the technology I had to then wait no more patience.

Although if I from a fixed net and/or a VoIP connection call fold it substantially better than from portable radio

nix rausgekommen… no call is on handy, nscht

in addition, wanted to know which box I have and which mac address….now main line train reef should be actually close with my gefreetzen to divide.

by the way: use callthrough straight over sipgate with 100%. CO2 can't DO

Hello, I has the same problems with CT.
It partial numbers doubly selected until 3-4 months ago ago had I no problems.
Had always thought it lay at Fritz box the update in December.
Also must call partly 2-3 times, so that I get at all a free character. Also the Umsetllungen in the Fritz box to the DTMF sounds has I already everything tried out….

Would be beautiful, if we would find a solution…

Jo, more @RedLeffer you has equal problem as I!!!

I had 7170 to and after I had ever more frequently problems, I had gotten myself the 7270 of CO2 - and firmware *.80 entbrandet drauf.

Thus off approx. Decembers 2009 began the problems with the DTMF tones

Someone tested times the whole with an old firmware thus before 12.2009.
I mean to have read here already times that with dtmf already times the nen problem of the Fritz boxes was, which was passed on also at AVM.

EDIT:

The old contribution again found:
http://www.ip-phone-forum.de/showthread.php?t=93509

I do not believe that it which with the firmware to do has. With my old FBF (firmware 06.04.33) I have the same problem as with the FBF 7270.
However I can exclude it not completely, since the old FBF ranhngt to the 7270 as client.

Had also times the codec up

Offerer supports G.726 after RFC 3551

changed over. Unfortunately also with it no DTMF success… Further ideas? Suggestions? Except nen other SIP offering nehmenr

Property straight this morning several times callthrough tries and with the Dtmf problems. Times it did not function - times!!!

Then I provided the Dtmf tones for each Internet call number on car and functioned immediately the direct-inward dialing.

Unfortunately I could not confirm this afternoon my property result any longer.

I have the old firmware of @Daniel (thanks you also here here)
FRITZ! Box hair dryer WLAN 7270 v3 Firmware design 74.04.76
gotten and these up easily.
CO2 is not here implemented and I had everything hndisch to enter.
To good the latter Dtmf attitude has itself still resisted as I this on car to place wanted - FB makes with each individual O2-Sip-nummer one resync with the assumption - why also always.
But… it seems to fold.
I could have had rung to mine from the CO2 mobile phone my callthrough number (*121# purely - *122# raus) to direct-inward dialings and then direct line *124#.
And the coronation/culmination was then still the fact that I could call with Nummer*123# my mobile phone - there was however unfortunately occupied

Tomorrow the attempts continue to go….

Have evenly times nen ticket with AVM opened.
Times see which it still to the topic to say being able.

A few days are so now by and I could me mine
FRITZ! Box Hair dryer WLAN 7270 v3 with firmware design 74.04.76
DSL version 1.52.34.11 DSL asset [4 day (e) 23: 35: 02]
now with direct-inward dialing and correct transmission of the DTMF please!!!

Since I had to enter the Provider CO2 with the firmware conditions *.76 hndisch as “other offerer”,
I go surely correctly in the acceptance that AVM only
afterwards in your software implemented the attitudes wished by CO2.
(This is naturally everything only an assumption of me as a layman. )

Are there to confirm to Profi's those that can?

CO2 believes fixed. Also in the 80's firmware I had no more problems for days.

Problem arises unfortunately still. Straight one evenly tested.

yo, and ' s becomes so slow correctly expensively with dtmf the malfunctioning…

are in Thailand landed, there costs the call 1€ per min over CO2 - sharpens

With the *.76 it firmware folds it… why also always.

@derkleineups

how does it look with you with CallThrough? It folds still?! If I may ask, how often have you it again since your last success message used?

With me it does not want simply. 99.9% committee

It folds still!!!
However after each restart DTMF transmission of “mechanism” is adjusted on “RTP or Inband” with me - amusingly I thought….

This evening me the idea came - for all Insider that was logical ^^ -
in of the “voip.cfg“the entry “must dtmfcfg = dtmfcfg_rtp_or_inband; ”
up "dtmfcfg = dtmfcfg_automatic;“to be placed.

Then it folds also with the DTMF tones

EDIT: Test please times everyone with DTMF problems: DTMF transmission on “Inband”

Now rennt's!! *jubel*
