"The best business telephones in the world."

Hi Snom Support team,

Currently i'm dealing with strange  behavior of different snom ip phone models like snom 360,, snom 370, snom D375 while connecting to banking conference using DTMF . Some models are recognizing conference ID and some are not able to recognize the conference ID given by the banking authorities. Are there any settings in all models to set dtmf enable all the time??? Would be very thank full to if can provide me some assitance in this regard. thanks    

Hi Alan,

well than what would be the best way out  other than replacement ? 

well same models sometimes responde and sometime times don't. and if i make a ccall using mobile phone at the same time than it works with mobile phone. strange behaiviour 

Hi Sean , 

Thanks for your reply . Well we have different ip phone models like

1- snom360 with firmware 8.7.3.25.9 and 8.7.3.25   (15 phones)

2-snom370 with firmware 8.7.3.25 and 8.7.5.35    (20 phones)

3- D345 with firmwares  8.9.3.33 and 8.9.3.46 (12 phones)

4- D375 with firmware 8.9.3.60, 8.9.3.46 and 8.9.3.15 

Yes the Bank IVR is not recognizing the DTMF being sent sometimes it accepted from the same models and sometimes it doesn't. and sometime after failure of 2 times. 

Furthermore when i try from mobile at the same time it accepted immediatly without any failure. WOULD be very thankful if u can resolve this strange behaiviour . thanks

One more thing is in the configurations i set 

dtmfmode = rfc2833 .

 The question is  can i add  both dtmfmode 

like 

dtmfmode=sipinfo 

dtmfmode=rfc2833 

in the same configuration ?

the current dtmfmode is rfc2833 

Ok i'm doing this will let you know about the status . thanks
