[asterisk-users] My Sip Provider lacks Sip 2.0 183 (Ringing) information

Hi all,

my sip provider does'nt send a 183 Message when the opposite party 
rings. It sends the ringing indication on the audio stream. Is there any 
chance that the asterisk can analyze this audio stream (meta) 
information. I saw there is a zaptel configuration entry that sound 
pretty close to what I need 'callprogress'.
Has someone already solved this problem?

Knud
