asterisk users - Jun 2005 - DTMF Tone Lengths

Good day,

	I am hoping that someone can assist me with a work around.

	I have an IVR system that I am attempting to connect asterisk
to, however the IVR was written 
	Some time ago, and requires tones to be approximately 2 seconds
in length.  I am using SIP
	Phones, Is there any way to adjust the Length of the Tones that
asterisk sends out the audio path?

	Are there any phones that would allow me to hold the "Buttons"
in and generate the tone for the entire length that it was held?

I have exhausted my friend "Google" and I think maybe I just am not
searching correctly, certainly others have crossed this chasm.

Thanks for your direction in this matter.

Someone else on the list had a similar problem, and as I recall, they
changed a parameter in asterisk to cause "it" to send longer dtmf
tones. That posting happened within the last couple of months.

Essentially the sip phone sends dtmf signaling via the rfc method 
within sip packets (not actual tones), asterisk interprets the
digits, and generates the dtmf tones. I don't have a clue where to
find the asterisk parameter to control that, but would have to guess
it is in a header file within the asterisk source directory.
