10.5.3_ER1 - An Overview of Features
F- 1408 Optimize DSP Densities per Codec
...
To accomplish the additional ports, a new profile was added. Profile 8 was created to allow a higher density of ports available on the IP leg. The profile is created in the hostflag parameter which resides in the dhcpd.conf profile. To configure the IMG to be able to process the increased number of transcoding sessions, the hostflag parameter must be changed to the new profile which is profile 8. Once profile 8 is configured in the dhcpd.conf and IMG is equipped with a Mindspeed VoIP Module, the VoIP Profile field within the Physical IMG object will display "High Capacity Wireless (# Picasso)". See links in Related Topics below for more information on accomplishing this.

F-5068 Full support for ITX <-> SIP INFO in FT ISUP SPIROU
...
SIP to SS7 - The IMG will accept the SIP INFO message (RFC 2976 - The SIP INFO Method) from SIP leg and generate an ITX message onto the SS7 ISUP leg.

F-5090 Mapping of ISDN Sub Addresses to SIP. (RFC 4715)
...
Feature F-5090 maps the ISDN calling party sub address parameters such as the Network Service Access Point (NSAP) to the SIP tel URI 'isub' parameter and its address identifier 'isub encoding' parameter. Feature 5090 maps these parameters from SIP to ISDN and from ISDN to SIP. Feature F-5090 follows the outline of RFC 4715. This feature was added and can be enabled/disabled from the SIP From Header Tags object in Clientview.

F-5134 Maintain Active Calls when links go Out Of Service
...
Since SS7 is a CCS protocol, the voice and signaling use separate channels. If a signaling link goes down, and the CIC is in a ringing or answered state, the call will be dropped and CIC taken Out Of Service. Feature F-5134 adds to the IMG the ability to keep any CIC's which are in the ringing or answered state 'In Service' until a subsequent condition exists that eventually will take the CIC Out Of Service. For more information on this feature or its functionality see the links under the Related Topics section below.

F- 5152/5215 DNS SRV improvements
...
Feature F-5152 adds to the IMG the ability to define whether the query to the DNS server will be for an A-Record, SRV Record, or a both. After the IMG does a DNS query it receives multiple responses from the DNS server. The IMG then sends an INVITE message to one of the SIP servers. Depending on the selection in the DNS Servers pane, the INVITE could contain any one or both of the above records.

F-5230 Multimedia Call Routing.
...
The H.223 and H.245 protocols are used to establish multimedia calls between endpoints over circuit switched networks. These protocols come into play after successful call completion between the multimedia endpoints. The initial SS7/ISDN call set-up messages contain an octet that indicate that the call will utilize H.223/H.245. Feature F-5230 'Multimedia Call Routing'' supports routing calls based on the presence of this specific octet. Routing is configured using the new routing criteria type 'Multimedia Call'. See links below for more in depth information on this feature and how it is configured.

F-5282 LNP Handling for SIP to SIP-I calls
...
Local Number Portability (LNP) allows a customer the ability to transfer either an existing fixed line or mobile telephone number assigned by a local carrier and reassign it to another carrier. The IMG now supports taking the LNP data in the R-URI on the SIP leg and interworking it into the R-URI and the ISUP MIME message on the SIP-I leg. The IMG also supports taking the R-URI message from the SIP-I leg and interworking it into the R-URI message on the SIP leg. Feature F-5282 is by default always enabled and does not need any special configuration for it to function. See links below in Related Topics for more information.

F-5287 DNS Load Balancing
...
Feature F-5287 adds to the IMG the ability to receive an SRV Record from a DNS Server, calculate the priority of the responses using a priority/weight/random number algorithm, and spread the calls over multiple SIP servers. This functionality is built in to the IMG and does not need to be configured separately. Load balancing and its random number algorithm are based on RFC 2782. See links below for more information.

F-5320 Bypass CUG facility field in IAM
...
The supplementary service Closed User Group (CUG) enables users to form groups, to and from which access is restricted. A specific user may be a member of one or more CUGs. Members of a specific CUG can communicate among themselves but not with users outside the group. Feature F-5320 adds to the IMG the ability to either Reject or Ignore a call which has the CUG parameters (interlock codes) embedded in the ISUP message. Closed User Groups are supported in E1 protocol only. ANSI does not have any provisions that support CUG parameters. See specifications in ITU Q.735 (03/93) and CUG format in ITU Specification Q.763

F-5328 Add ability for a Virtual Machine to run GCEMS
...
Dialogic will supply upon request the files needed (in OVF Format) to be able to use the VM on a Virtual Machine Manager. These files are then imported to a Virtual Machine Manager through use of Virtual Machine Client software. See the documentation of your specific Virtual Machine vendor for information on how to import and run your specific VM software. Dialogic successfully tested the Virtual Machine application software VMware ESXi 3.5 and VMware Server 2.0.1 from WMware®. See the link in Related Topics below. Once the VM has been created, there is an initial GCEMS configuration which will explain how to configure the network IP addresses and subnet masks.
