[asterisk-users] Can't detect remote answer

I think the default DTMF tone duration is 100ms, if you are dialing 10 digits, that ends up being 1 second delay just to dial the DTMF, not including inter-digit delays.   Try setting toneduration=50 in chan_dahdi.conf and see what happens.   If you make it too low your telco will miss some digits, you'll need to experiment.   You may need to increase it.   If the telco switch is busy, like in the middle of the day your minimum workable tone duration may be higher than in the middle of the night.

I finally got an answer on IRC, turns out the problem was callprogress=yes (a.k.a. screwupmycalls=yes).  Changing it to no and dropping the r seemed to work.  I'd like the feature to work properly, but it's more important that I'm able to actually make calls :)

I *am* now stuck with a long pause before I hear the outgoing ringing though. Not sure if there's anything I can do to tackle that one.

	Just quickly glanced over your data... one problem you have is that you're passing the 'r' flag in your Dial() statement in extensions.conf.  That would definitely cause you to have never ending ringback from the analog line (since answer supervision is often not present).  You might try removing that and retry your outbound call test.
	Hope that helps a bit.

		   3 WCTDM/4/2 Reserved
		   4 WCTDM/4/3 Reserved

		    *any* advice/suggestions at this point would be very much appreciated!
