[SR-Users] DMQ problems

[Charles Chance]

Hello,

Is there anything preventing the messages from reaching Kamailio? If you
have a pcap from one of the servers we may be able to see what’s happening.

Also, you have the notification address set to localhost - this should
instead point to one of the other nodes.

Cheers,

Charles

Why are you setting the notification address as localhost?
