Description:I want to use inband from my spa2000, which works fine except when calling the voicemail application.  I have since used dtmfmode=inband on all of my sip.conf entries, but this should be looked into anyway.

exten => *98,1,SIPDtmfMode(inband)
exten => *98,2,Voicemailmain(${CALLERIDNUM})

calling from a sip extension:
[5550222]
type=friend
secret=xxxxxxxx
nat=yes
host=dynamic
canreinvite=no
qualify=yes
mailbox=5550222
context=unlimited




****** ADDITIONAL INFORMATION ******

This does not happen with other modes and below are references to other complaints about this issue.

When going to in-band, be sure to allocate DSP (bug ASTERISK-1327)
