After removing the “transport=udp” from the config, it looks better, but some nodes are still duplicated in the messages going back and forth. In memory, as checked with dmq.list_nodes, it’s still only the proper ones without any duplication.

Dear Kamailians!
I’m trying to figure out DMQ and see how it reacts to server outages and downtime - the base protocol.
I’ve configured three nodes on different ports and run them locally. All have the others as notification peers plus one that is disabled. They are configured like this with transport:
modparam("dmq", "notification_address", "sip:192.168.40.107:5060;transport=udp”)
It seems like “transport=udp” is not supported. Only “transport=tls” is documented.

It quickly turns out that DMQ has every node twice - when sending ut “notification_peer” messages, it sends all six.
KDMQ sip:notification_peer@192.168.40.107:5070 SIP/2.0 Via: SIP/2.0/UDP 192.168.40.107:5080;branch=z9hG4bK96bc.875f2460000000000000000000000000.0 To: sip:notification_peer@192.168.40.107:5070 From: sip:notification_peer@192.168.40.107:5080;tag=e0f3ecb7441aaf62d1734fc723545165-9deb0be2 CSeq: 10 KDMQ Call-ID: 0024de987491cd3e-30304@192.168.40.107 Content-Length: 234 User-agent: Kamailio Server 02 DMQtest Max-Forwards: 1 Content-Type: text/plain

When I shut down one, it sends out a “disabled notification” where the other nodes responds that the other (copy) on the same IP/port is still active.
Looking into dmq with kamctl I see that three have transport “udp” and three have transport “*” (asterisk).
I don’t see transport being given as parameter in the notification_peer messages.
It seems to me like there’s a bug in here somewhere. Or is this the way it’s supposed to work?
