Ignoring Ring Ready (180)

You can ignore ring ready (180) but still "react" when receiving a 183 with media:

{ignore_early_media=ring_ready}sofia/internal/user@domain

ignore_early_media=ring_ready works the same way as ignore_early_media=true, but it also sends 180 to the inbound leg when the first 183 is caught.

Mit freundlichen Grüßen / best regards,

Hello.

My uplink usually gives ringback as both 183 Progress with SDP and 180 Ringing also with (different) SDP. One of my clients can't handle that behavior and it just don't plays ringback at all. Is it possible to relay only last provisional response with SDP and drop anything else 183? Any ideas plz? Can't figure out even a logic itself.

Thanks.
