This feature allows you to manage IMG IP addresses via DNS for greater flexibility and security than hard-coded alternatives in SDP and SIP.
You enter Fully Qualified Domain Names in the Fully Qualified Domain Name field of the SIP Signaling, SIP Virtual Address, and VoIP Module panes.
You configure outgoing FQDN options in the Outgoing Fully Qualified Domain Name field of the SIP Profile.
The radius dictionary file has been updated to support this feature. Customers using RADIUS should update the dictionary.cantata file they are using with the latest one located in the GCEMS install under ‘/opt/cantata/common/radius‘
On a freeRADIUS server this file should be copied into ‘/usr/share/freeradius’ directory.
The latest version of dictionary.cantata is v1.3:
# dictionary.Cantata
#
# IMG release 10.3.3 ER2+
# Version. $id: dictionary.cantata,v1.3 2007/06/29 $
Fully Qualified Domain Names Support
The IMG supports receiving multiple SIP 183 responses prior to a 200 OK for an INVITE request, when SIP responses can potentially be received from multiple remote user agents. A proxy or an Application server that receives an INVITE from the IMG can then fork the request to multiple destinations.
Multiple 183 responses are used in Follow-me services, and request forking scenarios. Applications that can benefit from the IMG handling multiple 18x responses are:
Application Servers
Proxy Servers
See Multiple SIP 183s prior to 200 OK.
This features allows you to translate a Null originating number only. This allows you, for example, to append a prefix to the originating number if the originating number is empty.
Ability to assign Net5 Q.931 variant on T1 ISDN D-channels
This feature allows you to configure Net5 Q.931 variant on a T1 ISDN D-Channel. This is required, for example, when connecting to carriers in South America where a far end using E1 is terminated in the US on T1s.
Enhanced variant support.
See the Supported Variants in the ISDN Features topic for a complete list of supported variants.
ISDN D Channel pane: Base Variant field
The IMG now supports up to 3 SNMP Managers.
With this feature the IMG will send a re-INVITE to the far-end when it detects modem traffic and switches the RTP into Modem Bypass mode over G.711. The IMG will use the bypass codec type specified in the associated bearer profile (u-law or a-law).
Incoming Re-INVITEs during modem calls are accepted automatically.
This feature is disabled by default. You enable it with the Outbound Modem Triggers Re-INVITE field in the SIP Profile.
With this feature the IMG supports out-of-band tone passage of a single DTMF digit (0- 9, *, #, a, b, c, d) using the SIP INFO method.
You enable this feature by selecting INFO DTMF digit relay in the Method field of the SIP DTMF Support pane.
See INFO DTMF Digit Relay for more information.
