Feature Description and Operation Manual

Networked systems are not designed to be non-blocking. Should no path be available to
complete the transfer, error tone is provided to the caller.
If the receiving station is busy, the transferring user will receive busy tone and may camp
the call to the busy station (refer to Ref. B). If the receiving station is in DND, the call is
rejected, the caller receives busy tone and cannot camp-on.

16.6.5 Network Camp-on (Call Offer)
Description
When calling to a networked station that is busy, the user may camp a call on to the called
station. The called station receives a camp-on tone and the [Hold/Save] button LED will flash.
Network Camp-on operation is the same as system Camp-on (refer to Ref. A) and is subject to
the same conditions.
From a network perspective, ipLDK employs H.450 Call Offer protocol to provide camp-on
capabilities.
Consideration
Call Offer is only applied when calling a station that is in an active call state.
Network Camp-on is not available with conference or page.
The ipLDK-60 System does not support Network Camp-on over ISDN CO lines employing
QSig.
