E_SIP_OPTIONS_Access (structure version 

≥ 0x108 only) 

Enables application access to incoming OPTIONS, and the ability to send OPTIONS requests. 
The following symbolic values are defined:

ENUM_Disabled (default) – disable application access to OPTIONS messages

ENUM_Enabled – enable application access to OPTIONS messages

sip_registrar_registrations (structure version 

≥ 0x109 only)

Specifies the number of unique SIP registrations that can be created. A unique registration is 
defined as a unique Address Of Record/Registrar pair, so registering the same AOR on a 
different Registrar is counted as a second unique registration. The range for this field is 1 to 
10000. The default value is sip_max_calls.

sip_tls_engine (structure version 

≥ 0x10a only)

Identifies a 

 data structure that specifies a number of parameters needed for 

SIP Transport Layer Security (TLS), including TLS port number, engine certificate, and 
trusted root certificate authorities. The default value is a NULL pointer (SIP TLS disabled). If 
the structure is not properly configured for TLS server or TLS client operation (or both), 
gc_Start( ) will fail with error IPERR_INVALID_TLS_PARAM. If this field identifies a 
properly configured data structure but TCP is not enabled via E_SIP_tcpenabled, gc_Start( ) 
will fail with error IPERR_INVALID_TLS_WITHOUT_TCP.
