First of all, if the wiki says "inline" (yes, okay, it does) it probably means as inline data as opposed to "inband." But the fact is that iax2 ALWAYS sends DTMF out-of-band.
While it's true that some VOIP phones (SIP adapters, etc) can be configured to send DTMF inband, I would think that doing so while using IAX is going to result in digits being reproduced twice at the destination--once from the DTMF reproduced from out-of-band and once from the inband DTMF. So if you're using IAX as your trunking protocal you need to use out-of-band DTMF on your IP phones (and adapters) as well.
Why does DTMF work sometimes and not all of the time? Heck, if I knew that then I wouldn't have this problem where inband DTMF hardly ever works properly for any of my inbound calls over IAX from Voicepulse. I'm starting to think that Asterisk's support for DTMF over IAX has issues but I'm too stubborn to switch to SIP and test that. I know I don't have any (zero, nada, keine, rien, etc.) problems navigating Asterisk IVR menus via my SIP adapter.
It's important to keep in mind, however, that the telco environment beyond your Asterisk box, beyond FWD (Voicepulse, Broadvoice, Vonage, etc.) is a complicated environment where everyone isn't playing by the same set of technical specs. The fact that any of this stuff actually works as well as it does is just amazing in itself.

Joseph has been working at bringing up an asterisk box as kind of a newbie, and I think he's using a Sipura as his fxs interface into asterisk. He's having a problem with asterisk passing dtmf to FWD, but didn't say how he's accessing the bank or fedex. So, without a fair amount more detail from him, there's no way to answer his questions or guess at the problem.
------------------------Exactly. (I was hoping he'd come to his own conclusions.) So... if the-------------------------
Sipura does not do IAX, then it's quite possible that you're not doing IAX
on the Sipura. Which means the whole "dtmfmode and IAX protocol" is moot...

No.

ifCan the Sipura SPA-3000 do IAX? -Michael

Actually, I don't know what might be the problem. I'm using Sipura SPA-3000 unit connected to standard cordless phone and connecting to FWD over IAX
1.)
If I call FedEx or Bank and enter my account number using numeric keys
it works
2.)
If I dial UPS 1-800-742-5877 and try to use one of the option provided
it doesn't work.
Could it be their phone system?

phones). Otherwise it's inband. The other options they provide just cutcall.
