VVX301 not connecting when connected to main network

[hi-impact_rich]

Hi,

We've got a number of Polycom phones in our office, a mix of VVX301 and VVX411. We had a change in router the other week which knocked 4 of the 5 Polycom Phones off the network.

I managed to get one back on by assigning a new IP Address.

I've also managed to get 2 of them back online by using a POE Injector.

The final phone that is not working, has not worked with either of these solutions. I have tested on a network outside of the office and it all works. I've also tested on a separate network that routes through our router and this works and can make calls.

Anyone any ideas on how to fix this?

Many Thanks

Rich
