IP call control library configuration information — IPCCLIB_START_DATA
• IPSET_TUNNELEDSIGNALMSG / IPPARM_TUNNELEDSIGNALMSG_DATA
Note: When using H.323, the stack limits the total size of messages to the value of this field
+ 512 bytes. Because of the presence of other payload in the message, it may not be
possible to use the maximum parameter data size defined in this field for H.323
Nonstandard Data or Annex M Tunneled Signaling Message data. If the total size of
an H.323 message is greater than max_parm_data_size + 512 bytes, the stack
truncates the message with no notification to the application.
