<div>Hi,</div>
<div> </div>
<div>I know it is a bit off-topic, but I'd like to ask the community what is the current most supported way to deal with DTMF?</div>
<div>I'm looking for an all-SIP system and I'm mostly interested in the end devices support of the different methods (DTMF in-band audio, DTMF RTP telephony events packets, SIP INFO, ...)</div>
<div> </div>
<div>Thanks in advance.</div>
