Yeah, those three cover the DTMF tones well!

Rosendo 4 months ago

What about SIP INFO? That seems relevant too.

Vallie 4 months ago

Agreed! In-band signaling is also a good choice.

Art 4 months ago

I think RFC 4733 is definitely one of the options.

Edda 6 months ago

Don't forget about the SIP-ISUP option!

Meaghan 6 months ago

Wait, are we sure about that? Seems too simple.

Una 6 months ago

Agreed, INFO and RTP are key for DTMF.

Carin 6 months ago

I thought RFC 4733 was the main one for DTMF!

Leana 6 months ago

SIP INFO method is definitely one of them.

Benedict 6 months ago

INFO_TRANSFER, INFO, and NOTIFY? Sounds about right. Now, where's the nearest coffee machine?

Portia 7 months ago

INFO_TRANSFER, SUBSCRIBE, and NOTIFY are the methods that can be used to pass DTMF tones. Easy peasy!

Desmond 7 months ago

INFO_TRANSFER, INFO, and NOTIFY - those are the ones I remember from the training.

Grover 7 months ago

I'm pretty sure INFO_TRANSFER, SUBSCRIBE, and NOTIFY are the SIP methods we need to know for this.

Benedict 7 months ago

INFO_TRANSFER, INFO, and NOTIFY seem like the right options to pass DTMF tones.

Isaac 7 months ago

I definitely remember SIP INFO and RFC 4733, but I’m not confident about the third option. Maybe in-band?

Alpha 7 months ago

I feel like there was a discussion in class about how SIP can handle DTMF tones, but I can't recall the exact methods.

Daisy 8 months ago

I think I practiced a question like this before, and I chose SIP INFO, RFC 4733, and in-band signaling.

Kimberely 8 months ago

I remember something about SIP INFO and RTP being used for DTMF, but I'm not sure if that's all of them.

Lili 9 months ago

Ah, I've got this! SIP INFO, SIP NOTIFY, and SIP DTMF-Relay are the methods that can be used to pass DTMF tones. Confident I can nail this one.

Sharen 9 months ago

This question is asking me to select 3 answers, so I'll need to identify at least 3 SIP methods that can handle DTMF. Time to put on my thinking cap!

Hollis 9 months ago

I remember learning about SIP and DTMF in class, but I'm a bit fuzzy on the details. I'll need to carefully review my notes to make sure I get this right.

Shawnna 9 months ago

Okay, I know SIP is used for VoIP, so DTMF tones must be relevant. Let me start by listing out the common SIP methods and see which ones might work.

Destiny 9 months ago

Hmm, this seems like a tricky one. I'll need to think through the different SIP methods and which ones can handle DTMF tones.

Don't forget about RTP payload! That's important for DTMF.

Tamar 3 months ago

↳ replying to Destiny

What about SIP INFO? That could work too.

Gregoria 3 months ago

I think RFC 4733 is one of the methods.
