Hello, After running FS for 5-6 hours we get calls disconnecting under 30 seconds. We are using enable-100rel=true After talking in irc with Matthew we disabled 100rel but now getting calls drop exactly after 32 seconds due to no response of ACK packet from FS. We are using 1 profile (external) for incoming and outgoing calls. Settings of the profile can be found here : http://pastebin.freeswitch.org/13783 There are hundred's of calls like this. We have now again enabled 100rel. Regards
