4 • CCS-UC-1: Crestron Mercury with Skype for Business Configuration Guide – DOC. 8256A
Known Issues and Limitations
• The Crestron Mercury device fails to register with SfB when the internal server or
external server is configured on the device.
• The Crestron Mercury device handles a transfer with two-way audio, but after the
transfer is complete, it drops the call.
• An attempt to add a PBX endpoint to a conference when the Crestron Mercury
device is already in a call with PSTN fails with an error informing that the PBX
endpoint is either unavailable or offline.
• The Crestron Mercury device does not play appropriate tones when it receives an
error code.
• The Crestron Mercury device is able to retrieve the call parked by the Skype
desktop client and there is two-way audio. However, after retrieving the parked call,
the call control options disappear from the Crestron Mercury device’s display.
• A hunt group call fails when the Crestron Mercury device answers the call (the hunt
group call succeeds when the SfB desktop client answers).
• No music on hold is heard on the PBX endpoint when the Crestron Mercury device
places the call on hold.
• The Crestron Mercury device handles call waiting, but it does not provide an option
to put the current call on hold to answer a second incoming call. The Crestron
Mercury device has to hang-up the ongoing first call to answer the second call, or it
can reject the incoming second call.
• When media bypass is enabled on the PBX, media is not being anchored on the
Crestron Mercury device. Instead, the mediation server anchors the media.
