1.51.4.5 gc_RejectInitXfer( ) Variances for IP
This function is only available if the call transfer supplementary service was enabled via
the sup_serv_mask field in the IP_VIRTBOARD structure when the board device was
started.
Variance for SIP
This function does not apply to SIP call transfer. The SIP stack does not contact the
Transfer Target or Transferred-To party (party C) until party A calls gc_InvokeXfer( ), so
there is no issue of accepting or rejecting the transfer at the initiation stage.
1.51.4.6 gc_RejectXfer( ) Variances for IP
This function is only available if the call transfer supplementary service was enabled via
the sup_serv_mask field in the IP_VIRTBOARD structure when the board device was
started.
The parameter parmblkp is ignored for IP technology.
The gc_RejectXfer( ) function can only be used at party B, and only after the receipt of a
GCEV_REQ_XFER event.
Variance for SIP

IPEC_SIPReasonStatusMax, as defined in the gcip_defs.h header file.

• host is a domain name or IP address
• param=value is an optional additional parameter
Note: When using the GC_MAKECALL_BLK *makecallp parameter to specify the
rerouting address, this parameter must be set to NULL.
