It is possible to configure a SPIP phone (running UCS 4.0.1) to send only RFC2833 packets and not send the tone audio over the RTP stream?

Hello 24x8,

 

I can only advise you to always check the FAQ before posting a new topic.


Oct 7, 2011 Question: Phone unable to send DTMF to an IVR system

Resolution: Please check => here <=

 

DTMF Inbound (within RTP) is RFC2833

DTMF Outbound (via SIP Info) is RFC2976

 

I am not familiar with sending no Tone but Audio Packets. 

 

Best Regards

Yes, of course. I always do, as well as having spent hours reading the UCS Admin Guide and experimenting with various options in our lab setup. I only post here as a last resort, in the hopes that someone else might have encountered a similar situation and/or might know that little tidbit of information that would save me many more hours of trial-and-error.

 

Unfortunately, that particular posting (nor any others I was able to find) doesn't really address my question, but thank you so much for your prompt reply.

Hello,

 

like I said above, I am not aware of a Inbound DTMF RFC that specifies that it would send packets but not generate the DTMF tone.

 

You can use SIP Info Outbound DTMF that cannot be "heard" by another Device/Person as it is not included within the Audio stream.

 

Best Regards

I wish to find answer between this replies, I'm going to use DTMF Decoder or SIM800L GSM module to decode DTMF but I tried a normal phone call and found DTMF is not hearable and with many devices. and later I found that mobile operators are transmitting DTMF signals through different channel than the normal voice channel. So I need to confirm if any DTMF decoder can decode this signals?
