Traces on DTMF code

[jpissot]

Hi,

THe Oxe R8 is connected to a SVI by an S0 access (declared as S0 phone).

The users call the the SVI and dial code to authentify them.

THe problem is that the SVI detect echo. Example, the user dial 1234 and the SVI recognize 12234.

I want to trace the DTMF code dialing by user. How i can do.

For information, there is an gateway PATTON S0/SIP between the Oxe and the SVI. Oxe connected to S0 bus and SVI connected by SIP.

THank you for your help.
