Hello Ovidiu, Thanks for the fix. In regards to the pings from eyeBeam - how do you want to reply to some dummy packages you do not understand ? Best regards Bogdan-Andrei Iancu OpenSIPS Founder and Developer http://www.opensips-solutions.com On 10/30/2013 01:28 AM, Ovidiu Sas wrote: I

The eyeBeam dummy packet is not that dummy. It's a 4 byte packet: CRLFCRLF. This is just like the TCP ping packet. We could reply with CRLF, as Saul suggested. See SIP outbound :http://tools.ietf.org/html/rfc5626#section-3.5.1 -ovidiu On Wed, Oct 30, 2013 at 7:07 AM, Bogdan-Andrei Iancu

I also have mixed feelings on thisQuestion : is the practice of using CRLF pinging via UDP a used one across UACs ?? or you just came across a corner/isolated case ? Regards, Bogdan-Andrei Iancu OpenSIPS Founder and Developer http://www.opensips-solutions.com On 10/30/2013 06:18 PM, Ovidiu

I came across this one by accident while dealing with STUN packets. The thing is that those CRLFCRLF packets are discarded silently and therefor is difficult to evaluate how often are they used. -ovidiu On Wed, Oct 30, 2013 at 1:18 PM, Bogdan-Andrei Iancu bog...@opensips.org wrote: I also have
