VVX 410 not ringin when called form PSTN

[evansmb0]

Have have a VVX410 on our lync network. The phone works fine when some one calls from another lync phone on site. However when some calls from PSTN the phone does not ring.  I have sniffed the connections  while a call is being made from the PSTN.  I see traffic start going to phone when a PSTN call is made, but the call never comes through.  Would anyone have any insite on this?

Thanks

Hello evansmb0,

welcome to the Polycom Community.

The LYNC server would need to send an INVITE to the phone in order for it to ring. If this does not happen the phone will not ring.

I suggest you check this on your end and then consult Microsoft Support.

Please be aware of the following when utilizing UCS 4.1.0 or later:

The use of Polycom UC Software versions 4.1.X (“Software”) requires the purchase of a separate Software license for every device that will use the Software in a Lync environment. You may not install, access, or use the Software in a Lync environment on more devices than are listed on your license until additional licenses have been purchased and authorized by Polycom. These licenses should be purchased from the same company from which you purchased the devices. You may operate devices against a Lync server for trial purposes for up to 30 days without purchasing a license. Use of the Software is subject to the terms and conditions of the End User License Agreement.

Polycom reserves the right to audit your deployment to verify that you have sufficient licenses to match the number of devices being used.
