I think that "BroadWorks Busy Lamp Field Interface Specification" explains why SPA942 BLF feature doesn't work with sipXecs, but can work with BroadWorks Application Server. BroadWorks doesn't send to the phone SUBSCRIBE request for a phone line monitoring (see SIP messages from [F7] to [F10] in section 8.1.3 of BroadWorks Specification). In other words, BroadWorks doesn't demand that phone informed it about line state (see section 7.2 of BroadWorks Specification). It is possible to assume that BroadWorks detects a connection state itself and notifies about it to all Resource List subscribers. Such service implementation corresponds to RFC 4235 which supposes use of State Agents on network side (see section 3.11 of RFC 4235).
