System Release 6.1 cPCI for Windows Release Guide — May 2006 15
Features
Intel NetStructure DM/IP boards support the following new IP protocol features in this
release. These features are new since System Release 6.0 cPCI Feature Pack 1 for
Windows. For information about many additional new IP protocol features that are
supported on both DM/IP and IPT boards, refer to the New Global Call Features for IP
Technology section of this Release Guide.
SIP re-INVITE
Three new API functions (documented in detail in the Global Call IP Technology
Guide) provide the ability to send, receive, accept, and reject SIP re-INVITE requests
when using DM/IP boards. The following specific capabilities are currently supported:
• refreshing SIP dialog properties
• changing the direction property of a media session (between half-duplex and full
duplex, for example)
• changing the RTP address of a remote endpoint
• implementing hold/retrieve functionality by suspending and resuming RTP
streaming
Note: To use SIP re-INVITE on DM/IP boards, the Early Media feature must be
explicitly enabled on each board using a new parameter, PrmEarlyMedia, in
the DM3 configuration file. See the DM3 Configuration Guide for details.
3.3 New Features for Intel NetStructure IPT Products
Intel NetStructure
®
IPT boards provide carrier-grade, open, standards-based platforms
that offer a highly scalable and flexible solution for IP telephony gateways and media
services. The boards provide IP services, enabling the optimal utilization of the next
generation network (NGN) architecture.
Features
System Release 6.1 cPCI for Windows introduces the following new features on the IPT
products. These features are new since System Release 6.0 cPCI Feature Pack 1 for
Windows.
Support for GSM AMR-NB coder
IPT boards support the GSM AMR-NB (adaptive multi-rate narrow band) coder for
applications that use the Global Call Library and the H.323 protocol, or the IP Media
Library. Eight different AMR-NB allowable rates from 4.75 kbps and 12.2 kbps are
supported.
Support for multiple IP addresses per board MAC address
IPT boards can be configured via the Intel Dialogic Configuration Manager to use up
to four different IP addresses for each of its Ethernet media network ports.
Applications can choose to use any IP address from the preconfigured trunk group on
a call-by-call basis.
