Feel stupid even asking this but we are replacing CX600 phones with VVX 500's and the VVX's refuse to get IPs form the DHCP server which runs on a Cisco Cat 3560 switch.  The CX600's get IPs fine as does any other device (workstations, phones, tablets, etc...).

 

We put them on another network with a different DHCP setup and they work fine.  Updated VVX firmware to latest version and that does not help.

 

What the heck is going on?  Is there something specific these phones need (bootp maybe?).

 

Anyone know?

 

Thanks

This issue persists occassionally at multiple locations using differnt switch type and DHCP servers.  Helpdesk now just know to add a static to the new phone to get up and running and once working change back to DHCP.    

 

Not looking for any additional info as we have a process to workaround the problem.

 

Thank you

Hello dMb,

welcome back to the Polycom Community.

Please ensure you always write the actually used firmware versions as week, months or years to come this may be important as nobody will know what that version was when you posted this.

 

The issue may be caused by the Cisco DHCP answering the DHCP IFORM with an ACK send as a Broadcast and not a Unicast.

 

In order to verify this please raise a case with Polcyom support via your Polycom reseller and quote VOIP-95799.

 

Please ensure to have your Polycom per LYNC license ready when doing so.

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

Hello murraybd ,
 

posting in this community is not logging a case.

 

Only your Polycom reseller can raise a case with Polycom support.

 

I am unsure if the original poster ever followed this up as advised but I have also replied to your post and explained what you have to do in order to bring this to Polycom supports attention.

Sorry to revive this thread, but that solution has not worked for me. Any others out there? I have looked everywhere... 

 

Cannot ping Static IP and when I put phone back to DHCP, I get the message : "FAILED TO GET BOOT. 500 seconds until reboot"

Sorry about that:

Polycom VXX410

Rev: 5.7.1.13261 

New phone bought from Amazon reseller. 

Phone worked on an HP switch for testing using an injector so I know it can pick up DHCP from other switches. When I connect it to my actual phone switch (Cisco ESW-48Port) it does not pick up an IP address. I've looked all over the place and cannot figure it out.
