CX3000 not connecting

We are evaluating a CX3000 in our new Lync environment. We have et the DHCP options and DNS for NTP but the phone does not connect. Is there a way to get the logs off the phone or to see the network configuration?

Re: CX3000 not connecting

Hi AlanW,

With the CX products, in most circumstances, all logs are uploaded by the device to the Lync server's Log folder. You can force a device to upload its logs with either of the following procedures:

- Before you sign in to the Lync 2010 Phone Edition device, on the System Information screen, tap Send Logs.

- After signing in, on the device Settings menu, tab Set Log Settings, and then tap Send Logs.



We have found that packet captures (Wireshark or equiv.) taken at the phone (using a hub or mirrored switch port) is an excellent tool with the Lync products. I'd recommend taking a trace of the phone booting to Idle Display, so you can see exactly what the CX device is sending and receiving from the network.


Also, we have this Knowledgebase article that outlines the configuration of a DHCP server for Lync devices:;jsessionid=72D59076E4B6E30C5FF3B26FB29...


In case you don't already have it, here is a TechNet article on the various locations for logs on the Microsoft Lync Server that should cover most standard Lync deployments:



If anyone else wants to add their thoughts/suggestions, please feel free to post up. :)
