Hi, guys

I have made progress on 1. i.e.  I dont hear any ringtone when I dial a 
number, I just hear the other person start speaking.  This is because 
the device that I am calling sends a SIP message 183 Session Progress. 
It used to work before, i.e. before when the device used to send SIP 
message 180 Ringing.  Now they have changed the specification on the 
device to send SIP 183.  Does asterisk recognise SIP 183.  What can I do 
to get ringing tone back?

Any help is really appreciated

thanks,
yusuf
