Hi all, We have had an upstream provider request that we enable 100rel support. I note in the wiki it says: enable-100rel This enable support for 100rel (100% reliability - PRACK message as defined in RFC3262 <http://tools.ietf.org/html/rfc3262>) This fixes a problem with SIP where provisional messages like "180 Ringing" are not ACK'd and therefore could be dropped over a poor connection without retransmission. *2009-07-08:* Enabling this may cause FreeSWITCH to crash, see FSCORE-392 <http://jira.freeswitch.org/browse/FSCORE-392>. <param name="enable-100rel" value="true"/> FSCORE-392 doesn't say if the crashing related to enabling 100rel was ever fixed. Can anyone confirm whether it is now safe to enable 100rel support? regards, David
