Hi,

I am receiving DTMF without any reason after call establishment.

The log as follows, and I suspect something related to directmedia,
[May 17 00:33:35] verbose[4238] app_dial.c: — SIP/MyTrunk-000a4b49 is making progress passing it to SIP/MAN-000a4b48

Is this some thing related to SIP RE-INVITE?

Thanks.
