Virtual Private Network • Fixed/mobile convergence • The VPN service integrates both fixed and mobile capabilities into the communication system of the company. The mobile and fixed phones of company users are then included into the company’s PNP (Private Numbering Plan). • Multi-site management • The company may be a group located on several different sites: the VPN service makes it possible for each site to have its own Private Numbering Plan, and calls between sites are considered as calls on private networks. • Private Numbering Plan • The Telecom Manager assigns private extensions to the site’s VPN users of the site users. Each VPN user can have more than one company line. Thus, a VPN user can call another VPN user in the same company by simply dialing a unique reduced number of digits. • The Telecom Manager can define PABX (Private Automatic Branch Exchange) ranges or/and individual PABX extensions in a site. Private extensions can be defined independently from of a PABX range. • The Private Numbering Plan may be either a structured or an unstructured PNP for all the sites of the group. • Preferred External Destination – • This feature allows a subscribing company to integrate non-VPN lines as preferred external destinations (for instance, partnerships, suppliers, customers, etc) by defining Preferred External Destination (PED) numbers (also called ABD) in the site’s Private Numbering Plan of the site. A PED number is associated with a complete public directory number (fixed or mobile) or a PABX range. • Group Hunting • The aim of Group Hunting is to manage the mobility of a VPN user by defining a list of numbers that, that can be called to reach the VPN user. • This feature allows routing incoming calls according to a sequential examination of the numbers in a Hunting List. It is activated either for company incoming calls or for incoming calls from an outside company when a VPN user is busy, or does not reply, or is not reachable. • A default hunting list, including the four user’s four lines and the voice mail is used if no dedicated hunting list or hunting list was specified for the VPN user.

Virtual Private Network • IN Call forwarding • Call forwarding is a routing feature managed dynamically by a given VPN user or operator when he/she wants to specify an alternative destination to for reaching him/her. Call forwarding has the priority over Group Hunting. This means that if a given VPN user activates call forwarding, the forwarded number is used to call him/her, even he/she has a Hunting List.; Group Hunting is processed when call forwarding is not activated. • Call forwarding can be processed in mobile or fixed networks or in company PABXs. • There are two types of call forwarding: • Call Forwarding Conditional (CFC): on busy, no reply or not reachable conditions. • Call Forwarding Unconditional (CFU): no condition. • CFU overruling • This feature enables some privileged calling parties (e.g. secretary or family member) to overrule Call Forwarding Unconditional (CFU) in order to call directly a given VPN user directly. • Voice mail management • Each VPN user can have a voice mail in the mobile or fixed network, or in the PABX. The voice mail can be used as a final destination in the management of IN call forwarding or Hunting Lists. • Exception lists • This feature allows the screening of incoming and outgoing calls of company users based on two types of lists - named called exception lists - containing “allowed” or “not allowed” numbers. • VPN lines • A VPN user can have more than one VPN line (e.g. PABX extension, mobile, a fixed phone in home etc). Up to four company lines can be defined for each VPN user. Each line may have its own extension (unstructured numbering) or may be identified by a line code before a unique extension (structured numbering). • In the framework of a structured numbering plan, this feature allows a given VPN user to call another VPN user by indicating the called line. Thus, the call is routed according to the used line code directly to the line of the concerned called party’s concerned line. If no line code is dialed, the default destination is used to route the call.

Virtual Private Network • On-net and Off-net calls • On-net calls are private calls made by VPN users to call other VPN users in the same group. • Off-net calls are calls made by VPN users towards the public network For making Off net calls PIN verification is there. • On-site and Off-site calls • On-site call: a call is said to be on-site when the cell phone is inside his the user’s site area. • Off-site call: a call is said to be off-site when the cell phone is outside his the user’s site area. • Forced on Net, Virtual on Net • The VPN service provides for two options regarding private rate charges for calls to public numbers: • Forced on Net: enables telephone calls to private numbers in the plan (fixed or mobile), dialed using the public format, to be charged at private rates. • Virtual on Net: enables telephone calls to Preferred External Destinations outside the company to be charged at private rates. • Account code • This feature enables you to mark calls made by VPN users of a given group in the company account according to the company activities and organization. • Dual invoicing • This feature allows you to bill calls made by a given VPN user either on the corporate account or on his/her personal account.

Virtual Private Network • Group short numbers • Group short numbers can be defined in the PNP (Private Numbering Plan) at company level. • Group short numbers enable VPN users of different sites to access public directory numbers or other PNP short numbers (except another short number of the same group) by just dialing the short number. • Welcome number • Welcome numbers are public directory numbers enabling external people (not belonging to the subscribing company) to make calls to dedicated VPN users (for instance, customer information service, technical support, etc). The welcome number is translated into a private number (for instance, group short number, extension or site short number) and is handled by the VPN service as a call made by a CMM user. • Remote access • With the Remote Access (RMTA) feature, VPN users can access the Private Numbering Plan of their site from any handset not belonging to the VPN group (in a national or international context), and take advantage of the VPN services (voice mail access, PED numbers, etc). This access is provided by means of a dedicated service code VPN Service Access Number and authentication. • Substitution • With the substitution feature, VPN users can access the Private Numbering Plan of their site from any handset of another VPN user of their group, and take advantage of the VPN services and to the rights granted to the said member line (voice mail access, PED numbers etc). This access is provided by means of a dedicated service code and authentication. • Follow-on call • With the follow-on call feature, VPN users can initiate, under some certain conditions, a new call without authentication after a remote access, substitution or dual invoicing call, or a new call after a call to the account code service without having to redial the account code. • Inter-working with co-operating VPNs This feature enables the VPN platform to inter-work with co-operating VPNs by routing to them or receiving company calls from them. • The sites of a group (i.e. a subscribing company) can be dealt with by several co-operating VPNs in different countries.
