asterisk users - Sep 2004 - Sipura-3000 - silent dial out on FXO port

I am trying to configure the FXO port on a Sipura-3000 for use with Asterisk.

When I connect to the Sipura to dial out on the PSTN line connected to
the Sipura's FXO port, it gives me the dialtone of the PSTN line and
then I can hear the DTMF for the number I dialled beforehand.

It does work but the customer perceives this delayed second DTMF
feedback as "unprofessional" and the sipura as a "toy". I
wonder if
there is anything that can be done to keep the channel to the caller
silent until after the Sipura has sent the DTMF out on the PSTN line.

Any hints appreciated.

thanks

Upgrade to their latest firmware. They changed that so its silent now.

Upgrade your firmware to the latest release. They solved that problem in 
the more recent releases (2.0.10 and above, IIRC).

or, if they have a sense of humor, tell them the equally unprofessional
cisco 1750 does the same
