[asterisk-users] DTMF issues/redial tones with rfc2833

[das sandesh]

Hi,

I got the captured packet traces and we could see that it was coming from
our asterisk server. Is there any other things that I need to look into,
also we have updated from Zaptel to Dahdi 2.0.2.2, but no luck, still the
random redial dtmf tones are coming in between calls.......Can anyone share
their opinion on this.......Thank you.

Regards
Sandesh
