DHCP Release issue VVX phones

Hello,

we are wondering if anyone has ever tested the DHCP behaivor if the VVX phone is unable to reach the DHCP server to renew an active lease.

 

We have tested a VVX 400 to make sure that the phone will loose the assigned IP address after lease has expired and the phone was not able to renew the lease. But what we see is that the phone is still responding to the old IP even after the lease was expired. And this could be an issue if the DHCP is assigning the same IP to another device in the meantime.

 

Regards

 

Marco

Re: DHCP Release issue VVX phones

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.

Best Regards
