What they have instructed you to do is enable dns srv on freeswitch, so they can use their newly-deployed loadbalancing to evade the DDOS.I have an impression that freeswitch UA supports DNS SRV out of the box. I need experts to correct me if that is wrong though._________________________________________________________________________

This was not a FreeSwitch issue, I was hoping for a quick check on Asterisk parm meanings so I could confirm to CC what I had. Would have been nice to get them, but CallCentric is back up with no changes on my part. Thanks for the suggestion, I will check them out.Mario GOn Oct 19, 2012, at 12:27 PM, Gilad Abada wrote:Why not switch to Flowroute if callcentric is so unreliable?

This is a critical request for help.... All 6 lines are out again today. I am forwarding inbound calls to a land lines but no one can make any outbound calls. Thanks for any suggestions.DDos Attacks have targeted Callcentric again, their instructions to me are for Asterisk not FreeSwitch (their info page for FreeSwitch does not help). I already researched the web for a week with no success. It may be buried in the wiki but I have not been able to find it. The parms they sent are below, can someone tell me what FreeSwitch equivalents are so I can get let them know it's right and possibly get back up?Mario GWe have discovered new information for Asterisk users. In order to get DNS SRV working properly you will need to set the following in your /etc/asterisk/dnsmgr.conf file:
[general]
enable=yes
refreshinterval=3600
And for your Callcentric trunk:
[callcentric]
srvlookup = yes
domain = callcentric.com
host = callcentric.com
outboundproxy = callcentric.com
register => 1234MYCCID:SUPERSECRET@callcentric.com
Besides user and password all I have is:They suggested changing 2 lines but then I get the error below:ERR] sofia_reg.c:2039 userid Registration Failed with status DNS Error [503]. failure #82
