[Freeswitch-dev] Session Progress and RINGING

A ---> FS ---> B

B does send a Session Progress to FS. FS will forward the Session Progress to A.
B does send a RINGING to FS. FS does _not_ forward this to A.

Could it be, that the check the switch_test_flag(channel, CF_EARLY_MEDIA) in mod_sofia.c within the INDICATE_RINGING section is wrong. I think it is allowed to send the Session Progress first and later the RINGING. The ringing is for example for SIP/ISDN gateways necessary.

Any hint is appreciated.

Best regards,
