Hi!
I have found the problem. It is indeed desired behaviour!
Current FW is 5.1.0. I have now browsed the realease notes from latest to
oldest and release 5.0.0 (first for Mitel 6900 series) states, that this
phone only works, if registered to Mitel call servers.
This remark is only listet there and in no other location. Seems like all
who buy this phone are currently out of luck.
The phone does not detect a Mitel call server and throws an internal 606
and disables the line until reboot.
Source: Page 14 of Mitel 6800/6900 Series SIP Phones 5.0.0 Release Notes
I never had such a case, where a vendor locks his phone to it's own
platform. In particular does not communicate this change.
Thanks for your help while debugging this. I have learned a lot during
debug.
Kind regards
Kevin

Hardly a guess, just experience, lol
You're welcome.

Since you are using Kamailio for auth/usrloc, sending its REGISTER with
_______________________________________________
Kamailio (SER) - Users Mailing List
sr-users(a)lists.kamailio.org
https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
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!
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!

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
