DHCP renew issue Trio 8800



is there any option to force the Trio 8800 to do a DHCP renew after the renew period has reached? What we see in our tests is that the trio does not renew the DHCP lease after x% of the lease time but wait until the lease has expired and starts a new IP discover afterwards. Is there maybe a parameter we can set via provisioning config file to fix this?

Hello @Marco Patzelt (BWI),

welcome to the Polycom Community.

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

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


Have you got a wireshark trace of the BOOTP exchange or maybe logs from the Triowith DCHPC at debug and overall debug ?


Settings > Logging > Global Settings > Global Log Level Limit > Debug
Settings > Logging > Global Settings > Global Log Level Limit > Log File Size (Kbytes) > Trio 10240

Settings > Logging > Module Log Level Limits > DHCP Client > Debug


Most likely this needs to come into support for us to verify.

In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.

End Customers are unable to open a ticket directly with Polycom support.

If this is some sort of an Internet discounter please post either your phone's MAC address or your Polycom devices serial so I can look up who would be able to support you. This may not be who you purchased the Polycom device from.

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

Re: DHCP renew issue Trio 8800


we have made some more testing and if we extend the lease time we see a renew in whireshark logs. Is there a minimum lease time we have to use? in our first tests the lease time was only 21 minutes. Could it be that this is to short?
