The GCEV_SERVICERESP event, which is received on an IPT board device handle, indicates that 
a service request has been responded to by an H.323 gatekeeper or a SIP registrar. This event does 
not necessarily mean that the registration operation itself was completed successfully, however; 
successful completion of the operation is indicated by the result code IPERR_OK. The event data 
includes a specification of the protocol used in the following parameter element:

IPSET_PROTOCOL

IPPARM_PROTOCOL_BITMASK
and one of the following parameter data values:

IP_PROTOCOL_H323

IP_PROTOCOL_SIP

When using H.323, the registration information that can be included in the GC_PARM_BLK 
associated with the gc_ReqService( ) function is shown in Table 38.
