On CUCM 10.5.2, I'm using 8851 phones (SIP) and need to have the Barge Feature on some calls. It's configured in the Softkey Template under Remote-In Use state, along with the New Call softkey. However, when the line is in use, the shared line is red but doesn't show the Barge softkey, only the New Call softkey. Privacy is turned Off on the phones, and Built In Bridge is turned On. Party Entrance Tone is turned On on the line. I want to allow a third party to join an existing call, or conference call. Is there something else that I'm missing? Or, are the 8851s and 61s not supported for this Feature?
