Table 28 through Table 31 list the possible event failure cause values.
numberstr Ignored in supervised call transfer – set to NULL.
For blind call transfer, used to provide address of party C (the rerouting address) as a
string. Signaled to party B in the GCEV_REQ_XFER event. Format can be:
• transport address, for example, “TA:146.152.0.1”
• E.164 alias, for example, “TEL:9739933000”
• host address, for example, “NAME: myhostname”
Note: The prefix must be included in the string to allow correct interpretation.
Note: When using the GC_MAKECALL_BLK *makecallp parameter to specify the
rerouting address via a data structure, this parameter must be set to NULL.
makecallp Ignored in supervised call transfer – set to NULL.
For blind call transfer, used to provide address of party C (the rerouting address) in a
GC_MAKECALL_BLK data structure. Signaled to party B in the GCEV_REQ_XFER event.
Note: When using the char *numberstr parameter to specify the rerouting address as a
string, this parameter must be set to NULL.
timeout Ignored. H.450.2 timers (T1, T2, T3, T4) are implicitly maintained at 20 seconds – set to
