Hello Amir,
what is your issue exactly:
- because of the missing DNS entry the dispatcher module would not detect the asterisk server as "down"
- because of the missing DNS entry your Kamailio would not (re)start properly
You could try with flag 16 to disable DNS resolution at startup in your dispatcher file:

Cheers,
Henning

I think if I could tell kamailio server that IF you did not find a DNS record it means that a server is down my solution would work.

The error indicates kamailio can not resolve the location of asterisk2. Try checking the dns (can you resolve it on the kamailio box?) or using the IP.

Hi I have created a kamailio container with docker and two asterisk container And this is my dispatcher list: 1 sip:asterisk:5060 1 sip:asterisk2:5060 and this is my both asterisk SIP.conf [Kamailio] host=kamailio port=5060 insecure=invite type=friend context=from-internal
The problem is that I use User-defined networks which has its own DNS when a container starts a dns record would be set If I start a kamailio first then start two asterisks the asterisk works fine because the name "kamailio" has been set in docker dns but I should restart the kamailio because at startup It could not resolve astersik dns records after the everything works fine but if the any of the asterisk instances crash/stop kamailio can not detect that because a dns record would not be available:
17(22) ERROR: <core> [core/resolve.c:1684]: sip_hostport2su(): could not resolve hostname: "asterisk2" 17(22) ERROR: tm [ut.h:309]: uri2dst2(): failed to resolve "asterisk2" 17(22) ERROR: tm [uac.c:452]: t_uac_prepare(): no socket found 17(22) ERROR: dispatcher [dispatch.c:3110]: ds_ping_set(): unable to ping [sip:asterisk2:5060]
It is kind of loop , I think maybe I can fix asterisk problem with asterisk realtime and set the sip.conf in database. anyone has any suggestion for this problem?
