The unified gateway supports user rights management by level and call barring policies.
unified gateway users are assigned four levels of rights from lowest to highest: default, normal, advanced, and privileged. Users at different levels have different rights to use supplementary services or make calls. By default, users are at the default level.
ϒ⁄Right levels for supplementary services
The rights at lower levels to use supplementary services are subsets of the rights at higher levels. Table 1 describes the mapping between service rights and user levels.
Table 1 Mapping between service rights and user levels
Call Right User Level |
Service Rights |
Default |
Users have rights to use local number query, call transfer, call forwarding, call waiting, abbreviated dialing, outgoing call barring, alarm clock, CLIP, password change, phone conference, unified access to the fax mailbox, call park, call right, ONLY, DND, multi-call, instant meeting and absent user services. |
Common |
In addition to services that users can use at the default level, users at the normal level have rights to use the RCB(only for POTS users), CBB, designated pickup, and group pickup services. |
Advanced |
In addition to services that users can use at the normal level, users at the advanced level have rights to use three-party call, simultaneous and sequential ringing, break-in, forced release, hotline, CTVMU, CTVMB, CTVMNR, CTFMU, CTVMO, call forwarding presence, call forwarding conditional, callback on no reply, and BLFservices. |
Super |
In addition to services that users can use at the advanced level, users at the privileged level have rights to use privileged user, secretary, secretary station services. |
ϒ⁄Right levels for call rights and call control by time segment
Users at different right levels have different rights to make calls. Call rights can be control by time segment so that users at a level can make calls only in a specified time segment. Table 2 describes the mapping between call rights and user levels.

The unified gateway can restrict calls as required. Table 3 describes the call restriction services.
Table 3 Call restriction services
Service |
Description |
Call barring by calling number |
Call rights that are classified by calling number include incoming and outgoing call rights, for example, local call rights, toll call rights, and trunk call rights. |
Call barring by blacklist or whitelist |
Call barring by blacklist or whitelist allows a user to accept or reject calls made by a list of users. ϒ⁄Users in the blacklist group can call only users in the whitelist group. ϒ⁄Users in the ordinary call barring group can call users in the same group or in the whitelist group, but cannot call users in the blacklist group. ϒ⁄Users in the whitelist group can call users in any of the three groups. |
Call barring by personal blacklist |
Call barring by blacklist or whitelist allows a user to accept or reject calls made by a list of users. The personal blacklist has a lower priority than the system blacklist. |
VoIP domain-based call barring |
IP PBX logically assigns some local users or office routes to a VoIP domain for barring calls and sets the maximum number of concurrent calls for this VoIP domain. When receiving a new call request, the IP PBX checks the calling and called parties' domains and the maximum number of calls allowed. If the maximum number of calls allowed is reached, the call fails, and the calling party hears an announcement. |
Password-based call barring |
unified gateway determines whether a user can make calls by asking the user to enter a password. The password is bound to the user's phone. |
Call barring by card number and password |
Users can use authorized card numbers and passwords to make calls from any phones in the office. This service supports the following two dialing modes: ϒ⁄IVR navigation dialing mode: Users enter the password-based call barring prefix, and dial a number as prompted. ϒ⁄Full number dialing mode: Users directly enter outgoing prefix*call barring service ID*password*called number# to make a call. |
PIN-Code Service |
The PIN-Code service enables differentiated call-out service rights for different users that share the same IP phone. |
Calling number authentication |
If the calling number authentication service is configured for the called number prefix involved in an incoming call from a local user or a trunk, the IP PBX initiates a request to the remote authentication dial-in user service (RADIUS) server to authenticate the calling number. If the authentication is successful, the IP PBX connects the call. If the authentication fails, the call fails. |
Call barring by region |
The IP PBX manages call rights for users who use different types of phones in various regions. ϒ⁄After users under the IP PBX are assigned to different VoIP domains, the IP PBX determines whether a call can be established based on the calling number, called number, or domain type. ϒ⁄This service meets VoIP restriction requirements of India offices. Incoming and outgoing calls cannot be routed through broadband and narrowband trunks. Different rights can be assigned to trunks to prevent trunk tandem calls. |
Anonymous call barring |
This service allows the system to restrict anonymous calls (including intra-office calls and outer-office calls) to a user. |
Restriction on outer-office call duration |
When a user under unified gateway makes an outgoing call to or receives an incoming call from an outer-office user, the IP PBX controls the call duration as configured and plays an announcement to the user when there is only one minute left. |
As long as the network between the IP phones and the unified gateway is available, users can make emergency calls in any state (such as unregistered, call rights restricted, or overdrawn state). The emergency call center can locate the calling parties.
ϒ⁄The emergency call service is still available in the following scenarios: account overdrawn, password-based call barring, call baring by card number, national/international toll call barring, intra-office call barring, outer-office call barring, call barring due to the full CDR pool, RADIUS authentication failure, and call barring by VoIP domain
