Issue with name from DHCP

Some VOIP devices that are being addressed via DHCP but are failing to register a name with the DHCP servers.  In other words, when the DHCP grants a lease for an IP address the DNS name field is blank. 

 

I have boot.log file.

Re: Issue with name from DHCP

Hello Budrys,

welcome back 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.

Also please explain what type of Polycom Phones you are talking about.


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 "Read First"

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

 

I suggest you provide some more detail on your issue and include any logs or wireshark traces.


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

Re: Issue with name from DHCP

Hello Budrys,

 

thanks for providing at least some basic information.

 

The Phone is not running a currently supported Version. The latest and only supported version is UC Software 4.0.11 or 4.0.10

 

If you need to stay on 3.3.x then at least upgrade to 3.3.5

Best Regards

Do we need to change something in our configuration to upgrade our phones?

Re: Issue with name from DHCP

My issue is that all my VOIP devices that are being addressed via DHCP but are failing to register a name with the DHCP servers.  In other words, when the DHCP grants a lease for an IP address the DNS name field is blank. 

 

I have boot.log file.

Re: Issue with name from DHCP

Hello Budrys,

Again the community's VoIP FAQ contains this post here:

Aug 24, 2015 Question:What basic network data is send and received by a Polycom phone?

Resolution: Please check this post => here <=

 

The above explains in detail what kind of network date is send or received and usually DHCP Option 12 is utilized to provide the Hostname to the DHCP Server.

 

You keep telling us that you have the bootlog but this does still not answer your original comment and repeated comment in regards of a DNS name.

 

Could you please do the following:

 

  • Upgrade the phone to a currently supported version
  • Specify in detail what you exact issue is and quote the relevant RFC we are violating
  • Specify what DHCP server you are using
  • Show us a working DHCP lease from another device which does not show the issue you trying to tell us about via a Wireshark
  • Show us a non working DHCP lease from the Polycom device which does show the issue you trying to tell us about via a Wireshark


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

OK.

 

How can I take data from my Polycom using Wireshark?

Re: Issue with name from DHCP

Hello Budrys,

 

you need a spanned / mirrored port for this. These kind of actions are industry standards so please work with your IT Team.
