<div dir="ltr"><div><div><div>Hi,<br><br></div>In the documentation I read the following for "ds_ping_reply_codes":<br><br>"Please note that the response codes the module accepts as valid reply to the
PING-Method are not only the ones generated from the remote servers, but also those
that are generated locally. E.g.: setting code=408 or class=400 will never set
a backend down even if it is, because internally the Kamailio transaction layer
generates a 408 in the case of no response from the remote server, and this
internal code 408 is accepted as valid value"<br><br></div>Then I can see you set class=4 which probably collides with the above statement.<br><br></div><div>Try removing the class=4 and give it a try. If it works, you can set specific 4xx codes afterwards(if needed).<br><br></div><div>---<br></div>Stefan<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, May 30, 2017 at 4:49 PM, Jean Cérien <span dir="ltr"><<a href="mailto:cerien.jean@gmail.com" target="_blank">cerien.jean@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><br><div>Hello</div><div><br></div><div>I am working with Kamailio 5.0 dispatcher module.
