Hi Julien, thanks for your reply - I really appreciate your feedback and your presentations at KamailioWorld, I hope to see you again in person soon.
Can you share some details on how many records you synchronize using DMQ and if you ever experienced any loss of records while synchronization using DMQ? The issue is, that on IMS the registration is typically set to 600000 seconds (1 week), as we have other mechanisms to get notified if a user is dropping out of the network (we get notifications from the LTE network itself) and a loss of registration data would result in a user not being reachable for a long period of time.
