[asterisk-users] Asterisk Sends 180-RINGING to UA even withprogressinband=yes

Reorder tone can be used for many things, is there anything I've missed?

All of these are defined by RFC2543. 183 is not defined until 2 years later.

Do you have any examples where ringing is indicated and it should not be? I
would really like to know, I am not trying to say you are wrong, I've must
have never encountered such a situation, if a recorded message is played
from the far switch, the audio should be passed, if it tone is played that
is legacy pstn if its over the network or the near end such as a PBX
generating the tone, anything that is digitally interconnected to a proper
ss7 network, be it an ISDN line, PRI or SIP provider, should pass proper
progress out of band. If you are using analog lines then get rid of
progressinband configurations and do as Mr. Wieling suggests.
