mobility of packets. Values are:
0x10: LOWDELAY
selects a minimum delay link or circuit for the datagram
0x08: THROUGHPUT
selects a high throughput link or circuit for the datagram
0x04: RELIABILITY
selects a high reliability link or circuit for the datagram
0x02: MINCOST
selects a minimum cost link or circuit for the datagram
0x00: No Priority
the datagram has no priority assigned
1.45.3 Restrictions and Limitations
The following restrictions and limitations exist for IP support on the DI0408LSAR2 Boards:
• Single processor systems only – DI0408LSAR2 ML3 and ML5 are not supported on
multiprocessor systems.
• PTR 30285: When using VAD with G.729A/B codec, the application must explicitly set
the VAD field in the IP_AUDIO_CAPABILITY structure to GCPV_ENABLE. Otherwise,
the application could hang when invoking gc_AnswerCall( ).

DI0408LSAR2 Board Support for Host
Systems with Multiple NICs
This release provides the capability to specify an explicit IP address for use by all
Dialogic
®
DI0408LSAR2 Boards for RTP/RTCP processing in the system. If an explicit IP
address is not specified, the first Network Interface Card (NIC) address returned from the
socket function call gethostbyname( ) is selected automatically and assigned as the IP
address.
The explicit IP address can be set with the Dialogic
®
Configuration Manager (DCM) as
well as with the NCM API (NCM_SetValue( ) and NCM_GetValue( ) functions). The new
parameter is HostIpMediaNetworkAddress and appears on the Misc property sheet in
DCM. It is a global-level parameter that applies to all DI0408LSAR2 Boards in the system.
Enter the parameter value using standard decimal notation, xxx.xxx.xxx.xxx.
Note: This is the IP address for the IP media (not the IP call control signaling) and only for
boards using the Host IP Media Service (not Dialogic
®
DM/IP Boards with on-board
NICs). Refer to the figure below.
