Plantronics CS70NC -- Behaves oddly on SPIP650 phones

[Anonymous]

After reading FAQ, perusing the Feature Descriptions and Technical Notification, and searching the forums (found [this](http://community.polycom.com/t5/VoIP/Using-plantronics-CS70n-on-Polycom-IP330/m-p/4819) post, but it's not that helpful), going over the Polycom [docs](http://support.polycom.com/global/documents/support/technical/products/voice/Headset_Compatibility_L... regarding the matter I haven't found anything similar, either here or on the Plantronics website.

So the problem is that after I set everything up as indicated by Polycom/Plantronic, the earpiece can only be used to place a call.  When an incoming call to the SPIP650 happens, the earpiece rings, but pressing the pickup button does not connect the call.  All other Polycom phones I have tested this with (SPIP450, VVX 500) work fine.

Are there any known issues with the Plantronic CS70NC and the SPIP650?

Hello Kyle,

could you ensure that you set the following log levels:

hset="0"
logl="0"

You can do this via the Web Interface.

Can you answer the call when you press the Headset Key on the phone itself?

Please provide all this information when you raise the case via your reseller.

Regards
