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.

  Fix a problem with inband DTMF detection on outgoing SIP calls when
dtmfmode=auto.
  
  When dtmfmode was set to auto the inband DTMF detector was not setup
  on outgoing SIP calls. This caused inband DTMF detection to fail.
  The inband DTMF detector is now setup for both dtmfmode inband and auto.
