Summary:                    [patch] Inband DTMF on outbound call is not detected
when dtmfmode=auto
Description: 
Inband DTMF on outbound call is not detected when dtmfmode=auto
because p->vad (DSP for detecting inband DTMF) is not created.
On outbound call, p->vad is not created in sip_new(), so should be
created
in process_sdp() when dtmfmode is switched to inband.

I have tested only on 1.2, but I believe that it happens on 1.4 or later.

Attached patch will fix the problem.
