„ Description

The IP_TUNNELPROTOCOL_ALTID data structure is used in H.323 Annex M tunneled 
signaling to identify the protocol using alternate ID information. This data structure is used as the 
value of a Global Call parameter element of type IPSET_TUNNELEDSIGNALMSG / 
IPPARM_TUNNELEDSIGNALMSG_ALTERNATEID. This data structure is not used when the 
tunneled signaling message uses a protocol object ID to identify the protocol. 

Applications should use the INIT_IP_TUNNELPROTOCOL_ALTID( ) function to initialize 
the structure with the correct version number and initial field values.

„ Field Descriptions

The fields of the IP_TUNNELPROTOCOL_ALTID data structure are described as follows: 

version 

the version number of the data structure; the correct value is set by the 
INIT_IP_TUNNELPROTOCOL_ALTID( ) initialization function and should not be 
overridden by the application 

protocolType 

a string that identifies the tunneled protocol type
maximum length: MAX_TSM_ALTID_VARS_LENGTH 

protocolTypeLength 

the length of the protocolType string

protocolVariant 

a string that identifies the tunneled protocol variant
maximum length: MAX_TSM_ALTID_VARS_LENGTH 

protocolVariantLength 

the length of the protocolVariant string 

subIdentifier 

a string that provides additional tunneled protocol identification
maximum length: MAX_TSM_ALTID_VARS_LENGTH 

subIdentifierLength 

the length of the subIdentifier string
