Speeding up the dial of DTMF's in SIP channel

[chip (at) innovates.com]

When using dtmfmode=info, Asterisk is hard coded for 250ms
tone duration in chan_sip.c

I've changed this to 100ms without any ill effects.

Subject: [Asterisk-Users] Speeding up the dial of DTMF's in
SIP channel

I'm dialing DTMF's in a SIP channel using the options:

[sip.conf]
dmtfmode=info

[extensions.conf]
exten => _XXXXXXX,1,Dial(SIP/gateway,,D(${EXTEN}))

(this is a custom SIP gateway, which receives the DTMF's sent
from 
softphones through Asterisk, and based on them, build the
destination 
PSTN number).

My problem is that Dial send the DTMF's to the SIP/gateway
user at a 
rate of about 1 DTMF each 300ms. I'd like to know if it's
possible to 
speed up that rate, or even, if it's possible to send the entire 
extension as a single DTMF string.

Does anybody has a clue about how to do this? I was looking
the options 
for the Dial command, and nothing like that appears on it.

Thanks a lot for your help.
