Delay in sending DTMF tones on S60 3rd edition

swatitrehan — Fri, 02 May 2008 13:31:03 +0200

I am trying to send DTMF tones on a connected call (using CTelephony::SendDTMFTones). According to my experience, sending 10 digits takes more than 5 sec.

Kindly suggest an approach of sending the DTMF faster.
What could be the reasons of such a behavior? Please help!
