Hi Simon,

We have a problem with a piece of CPE after changing the PSTN gateway manufacturer. We no longer get a ringing tone !
but at the end, it the call established? It's only about the missing ringing tone?
So I was trying to emulate the original packet sequence and I noticed that the new gateway sends out 183 messages. So I was trying to remove them just incase the CPE was getting confused.
183 reply is used by gateways to send early media. In this case the ringing tone is actually send as RTP stream by the gateway (usually SIP devices play ringing tone locally when 180 received). Maybe your problem is that the RTP media from 183 (check the SDP body) is not correct or the media itself doesn't contain the ringing sound :-).

Hi Simon,
Currently there is no way to drop a reply from onreply_route. Is this really needed, no other way around?...maybe altering the reply... ?

I would like to stop 183 Session Progress messages. I can see then arriving and being dealt with by the onreply_route code, but how can I
stop then being forwarded by the sip server ?
Thanks
