[Freeswitch-users] Loss of first second of media

Sat Oct 30 08:57:23 PDT 2010

Ok, so I've finally found the problem. I'm connecting to the softphone first
then transferring to the gateway, but in the a-leg connection to the
softphone I had set ignore_early_media=true. I tried removing that and it
works now.

Presumably it's correct that SDP wouldn't be sent at 180 Ringing with that
flag on - but that's above my pay-grade, I'm just happy to have it working.

Thanks for your help Anthony,

Regards,
Fraser
