Table 71 shows the parameter IDs in the IPSET_TUNNELEDSIGNALMSG parameter set, which 
is used when sending or receiving tunneled signaling messages (TSMs) in the H.323 protocol.

IPPARM_
TSM_CONTENT_EVENT 

Type: enum

Used to identify the type of Global Call event to 
retrieve TSM content from. Values include:

• TSM_CONTENT_OFFERED 

• TSM_CONTENT_PROCEEDING 

• TSM_CONTENT_ALERTING 

• TSM_CONTENT_CONNECTED 

• TSM_CONTENT_DISCONNECTED 

• TSM_CONTENT_EXTENSION

IPPARM_
TUNNELEDSIGNALMSG_
ALTERNATEID 

Type: IP_TUNNEL
PROTOCOL_
ALTID

Size: sizeof(
IP_TUNNEL
PROTOCOL_
ALTID)

Used to contain a tunneled protocol alternate 
identifier in a tunneled signaling message 
(TSM). Either this or the tunneled protocol 
object ID must exist in a TSM. If the application 
is using a tunneled protocol object ID when 
sending a TSM, this parameter should not be 
inserted in the GC_PARM_BLK.

H.323 
only 

IPPARM_
TUNNELEDSIGNALMSG_
CONTENT 

Type: string †

Size: max length= 
MAX_IE_
LENGTH (255)

Used to contain any data content of a tunneled 
signaling message (TSM), which is a sequence 
of octet strings.

only 

IPPARM_
TUNNELEDSIGNALMSG_
NSDATA_DATA 

Type: string †

Size: max. length= 
max_parm_data_
size ‡ (configured 
via IPCCLIB_
START_DATA)

Used to contain any non-standard data in a 
tunneled signaling message (TSM). If no non-
standard data is being sent in a TSM, this 
parameter should not be inserted in the 
GC_PARM_BLK.

only 

IPPARM_
TUNNELEDSIGNALMSG_
NSDATA_H221NS 

Type: IP_H221
NONSTANDARD

Size: sizeof(
IP_H221NON
STANDARD)

Used to contain an H.221 non-standard data 
identifier in a tunneled signaling message 
(TSM). When sending non-standard data in a 
TSM, ether this ID or the non-standard data 
object ID must exist in the non-standard data. If 
non-standard data is not being sent, or if a non-
standard data object ID is being used when 
sending a TSM, this parameter should not be 
inserted in the GC_PARM_BLK.

† For parameters with data of type String, the length in a GC_PARM_BLK is the length of the data string plus 1. 
‡ The full maximum length that is configured may not be usable in practice because the H.323 stack limits total message size 
to max_parm_data_size + 512 bytes. Longer messages are truncated without notification to the application.
