I had tried that dialer, but it doesn't work on the bridges that I call into for conference calls. Just to be on the safe side, I just tried it again, but still no luck. It seems the bridge doesn't hear anything. I've also tried the gizmo clients dialer (on the little set of tabs, there is a >, and if you hit that enough to get the rightmost tab, it is the dialpad), but it didn't work either.

Hmmm, wait a minute, though. I *was* able to use the dialer to dial 1 to accept a call coming in through grandcentral. So there is something more at work here than I thought.

Alright, I'm going to try something fancy. I'm going to tell my work sip account to use grandcentral, as my outgoing phone, and have grandcentral ring my gizmo sip account, using the built in internet call client on the n810. From my work sip account I will set the outgoing number to be my conference bridge and ...(dramatic pause)... a puzzling half success. The DTMF worked to accept the incoming grandcentral call, and during the call it set recording on and off (the 6 key?), but my bridge didn't hear anything, including that 6 key that is part of the passcode.

Could it be that the length of the DTMF tones needs to be lengthened for the bridge, but they are long enough for grandcentral? I have heard of DTMF duration being a problem for some IVRs before, so maybe that is it. However, I didn't see any setting to let me play with DTMF duration in the buit in client or in the gizmo client. Oh well. Thanks IcelandDreams, for motivating me to try again. If I periodically poke at it, it's got to work eventually.

Ah, if it were only just one extra step...

In all seriousness, though, most consumers are newbies and they want to stay that way. The one extra step may well be worth their while, but unless they've had 7 friends tell them it is worth their while and they just *have* to do it, they won't.
