We have a problem with polycom 6000 and 7000, we have to restart them every morning so that they can function ...

We do not have the problem with polycom 5000
We have checked all the network parameters and they are the same.
The only difference is over the duration of the dhcp lease.
The duration of the Polycom 5000 (and SNOM) DHCP lease is 12 hours.
The duration of the dhcp lease of Polycom 6000 and 7000 is 24h.
Note that there is no difference on the DHCP server (Xivo)

The polycom 6000 and 7000 have been reinstalled, we are still obliged to restart them for it to work.

How can you change the duration of the DHCP lease on the polycom 5000 and 7000?

thank you for your reply

Hello @BenP,

welcome to the Polycom Community.

It is always useful to include the currently used SIP or UC Software version as issues experienced or a question asked may already be addressed in a newer release.

Please also include if you are using a SIP server or a LYNC / Skype for Business server.

If LYNC or Skype please provide Version details and if these are on premise of off premise

This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.

The above is also stated in the "Must Read First" and is the absolute minimum requirement every new post should include. .

In addition providing us with this basic information gives Polycom an idea what Software Versions are used in the field and avoids wasting time trying to troubleshoot issues which have already been addressed.

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP or UC Software Version of my Phone?
Resolution: Please check here


Secondly the DHCP Server is the one offering the Lease Time.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
