I am trying to initiate a "PickUp" from a Third party (Basic) SIP phone, which ends up sending a SUBSCRIBE message to the CallManager 6.

The reply from CM6 is as above.

Does this mean that this capability is not supported for "Basic" SIP phones ?

Or is it another CM feature that needs licensing ??

Any pointers would be highly appriciated.

From the Features and Services Guide:

"Call pickup notification, audio, and visual alert only supports licensed, third-party SIP phones."

Sounds like the SIP Phone is not meeting this requirement.

So I take it this means only "Cisco" SIP phones are "licensed" ?

Do you know what "license" are they talking about anyway ?

I assume that its perhaps interoarability with SIP extensions, that are licensed currently only to "Cisco"

I am not totally sure, but I think it has to do with the way the SIP Phone interoperates with the CUCM; and not any type of DLU, license file, etc.
