I would assume the phone sends multiple REGISTER requests with same CallID, one or more of which has an expire=0, as a NAT traversal technique trying to discover its public IP at first. May be it doesn't do it very well.
I have checked again and indeed, correct guess!
Since you are using Kamailio for auth/usrloc, sending its REGISTER with
expire=0 would indicate that the Kamailio contact has expired (probably after such a request was received from the phone). Try checking it with 'kamctl ul show'
Correct as well, endpoint is not listed there.
I will check if I can get debug from the phone.
Thank you very much!

It's not clear what kamailio/asterisk integration method you are
using.
Looking at the 2 provided messages - the 2nd one is not a relay of
the 1st
one.
I might have matched the wrong transaction. I use HEP/HOMER to observe communication and Kamailio starts a new flow (=Call-Id) to asterisk
(this
message is no coming from the phone).
handle authentication/usrloc in Kamailio? or using PATH extension?
I do auth + usrloc in Kamailio, no PATH.
Maybe the Kamailio debug would lead me to the problem but verbose level
3
has too much info.
Hi Kevin,
you could control the time when the specific not-working phone send a REGISTER. Then you can enable the debugging for a few seconds during this time, and then deactivate it again. This should work even on a production server. Debugging it on a test server is of course an even better way.
Best regards,
Henning
