That is the reason we are using RFC.2833 for call setup (going through our prompts + digits establishes the call). That guarantees that we connect.
We save BW by releasing media when possible. When INFO is working (and that is a big amount of our calls), the mid-call feature is provided.
We found that it's not the just ORDER that might not work (we don't care much about order) but it might never arrive.
Some carriers don't support it, most don't guarantee it end-to-end.

Now how do I get this working without the kindness of carriers?
I'm re-building our DEV environments and due to some equipment limitations, I can't bring in a trunk for testing only (trunk cost, sbc cost, etc).
Willing to build something as a managed mini-app. Asking the community first.

Again, this is not a PROD but a DEV problem. I can hack it. But I need it, otherwise we have no way to test some features before releasing them.

THX a lot!

Fun part of INFO is order in not guaranteed ;)

Sorry for the spam Brian, but here is the answer to your question: for active calls, we release the media to the cloud whenever possible (so no rtp or rtpeven, just sip to our system). We provide a mid-call feature that detects DTMF from users even when media is released to the cloud. We count on SIP INFO for this feature.
We do a lot of DTMF processing during call establishment as well and that is rtpevent driven.

Btw, Brian, I am fully aware that this is not a desired behavior, but I would have to overhaul a bigger system (including lots of Q.E testing) to fix it on our side.
Big impact, otherwise I would do it, not look outside of the system for a hack.
Thanks for your help.

I know it usually is one or the other but that's how one of our legacy server pair works. I wouldn't ask for it if I wouldn't need it.
Is there a way I can get this working from the FS PBX side?
Thank you.

Thats only for reception.   Notice 'My SIP trunk needs DTMF as SIP INFO **AND** RFC.2833.’, Why do you need to send both?
