ATA 187 No spanning tree with voice vlan

Hello,

Wondering if anyone else has see a switchport stop forwarding when an ATA is connected and the swtichport voice vlan is set?

I am experiencing this with ATA 187's on all of my switches.

Thanks,
Dan.

You may have some particular switch configuration causing that.

All of the ata186's work fine, I guess the 187 doesn't like the voice vlan configured.....

That is very close to my problem, except when I enter the commmand "switchport voice vlan xxx" then spanning tree stops working.  I don't have a static vlan set on the at as I set it back to factory defaults, unless it always has a static vlan set anyways?

Thanks
Dan.
