SfB buddy list precense is not updating on VVX600 and expansion module



We are experiencing an issue with two Skype for Business (on-prem) users using VVX600 phones and expansion modules not updating presence information of their buddy list. All of them stay as "Away"... what we noticed is that it happens after switching from off-hours to office-hours or after VVX600 phone is idle for a few hours. If they use Skype for Business soft client there is no such issue.

All phones are running UC Software Version

As I can see in the logs presence flow is going OK users are sending subscribe,service and benotify messages correctly and the front-end server responds with 200 OK.

It is quite strange because we have a lot of other phones with no such issues. Do you know what could be the reason?


Thank you.

Hello Hello Nikolay,,

welcome back to the Polycom Community.


A couple of your old posts => here <= are still open / pending as you have not marked these as "Accept as a solution" or at least provided some form of feedback or answer.


If they are in this state nobody finding them via a community search will know if an answer or advice provided was useful and has maybe helped you.


You could also add a Polycom Service Number as some of them referred you to open a ticket.


Could you therefore kindly go over them and mark or answer as appropriate ?


If they are marked as "Accept as a solution" other users can find these easier and it helps them to utilize the community more efficiently. 



For your current issue I suggest you get this into support as only the Support team can troubleshoot this and fix this if that is a software issue.


You can check this post here first:
