Introduction The Accelerator extends enterprise PBX functionality to mobile devices allowing end users to be more productive and accessible when out of the office. The Accelerator integrates mobile devices with existing Private Branch Exchanges (PBXs) so that the PBX sees the mobile device as simply another desk phone. This allows the existing PBX feature set to be applied consistently across both devices. Mobile specific functionality is then layered on top. PBX Dependencies License Key To use the Accelerator with a SIP Trunk PBX, the following software licenses may be required on the PBX: SIP Trunk licenses equal to the number of maximum active calls to/from an Accelerator mobile One SIMRING license per Accelerator subscriber who wishes to use both their desk phone (or soft client) and their Accelerator mobile Simultaneous Ringing (SIMRING) If the Accelerator mobile is to be used in conjunction with a desk phone (or soft client), the SIP Trunk PBX must support a SIMRING feature that allows an incoming call to ring one or more devices simultaneously.

SIP Trunk PBX Provisioning This section describes the provisioning steps required on the PBX. Configuration of SIMRING feature The SIMRING feature allows an incoming call to ring two or more end user devices simultaneously. In order to include the Accelerator mobile in an end user s ringlist, the SIMRING feature must be configured to route to an alias Directory Number (DN) in addition to the user s existing devices/dns. The alias DN is then routed to the Accelerator by the PBX (see the Translations Provisioning section below). See your PBX documentation for specific information on provisioning this functionality within the PBX. Translations Provisioning Pilot Directory Numbers (PDNs) need to be allocated in order to route calls into the enterprise for handling by Accelerator (refer to the Accelerator Provisioning Guide for more details on PDNs). Translations need to be set up within the PBX to route these inbound calls over the SIP trunk that is connected to the Accelerator. Alias numbers may also need to be set up to support the simultaneous ringing capability of the desk phone. These alias numbers should be set up to route over the same SIP trunk to the Accelerator.

Accelerator Provisioning te: This document assumes that the Accelerator has already been provisioned with: - Enterprise information - Wireless carrier information The integration process includes the following steps: 1. Define a Trunk Dial Plan for the SIP Trunk PBX in the Accelerator (optional). 2. Define the SIP Trunk PBX in the Accelerator. 3. Define a SIP Trunk Group/Trunk to route traffic from the SIP Trunk PBX to the Accelerator. 4. Define Pilot Numbers (optional but recommended) - PSTN routable number(s) that represent the mobile route into the enterprise network. The enterprise network must be provisioned to route calls for each pilot number to the Accelerator. 5. Define the Call Service Pilot Numbers - Used for the Call Move service. 6. Define Least Cost Route information for SIP trunk traffic from the Accelerator to the SIP Trunk PBX. (optional). 7. Define the Voice Mail system used with the SIP Trunk PBX. 8. Define Subscriber Dial Plans in the Accelerator. 9. Define Accelerator subscribers that use the SIP Trunk PBX. The steps below describe the unique configuration areas needed to integrate the SIP Trunk with the Accelerator. Refer to the Accelerator Provisioning Guide for a comprehensive explanation of Accelerator provisioning. Voice Network: PBX unique configuration items are required for adding a PBX.

Accelerator PBX Level 2 Integration Table 2 Accelerator PBX Level 2 Integration Feature Support Comments Call Accounting Codes Call Coverage/Hunt Groups Call Line Identification Restriction (CLIR) (Mobile) Call Pull (Desk->Mobile Call Move) Call Push (Mobile->Desk Call Move) Class of Restriction (COR) (PBX) Class of Service (COS) (PBX) Integration Level 2 provides the subscriber more advanced features than more commonly used basic features. The following features are considered Level 2 integration targets: Call Accounting Codes - To support the mobile office environment, client billing must be supported when the user is away from his/her desktop phone and using a mobile phone. For example, law offices, accounting firms, consulting firms and other organizations benefit from tracking the length of a call for a client. Client billing is achieved by having the user enter a code to specify that the call relates to a specific client matter or account. The code, which is often referred to as a client matter code (CMC) or call accounting code, can be assigned to customers, students, or other populations for call accounting and billing purposes. Call accounting codes are used by enterprise to manage call accounting. Call Coverage/Hunt Groups - Allows a group of extensions to be set up to handle multiple calls to a single telephone number. For each call to the number, the PBX hunts for an available extension in the hunt group and connects the call to that extension. The Accelerator can be defined as one of the extensions.

Appendix A: Multiple Call Appearance for rtel DMS-100 PBX For a rtel DMS-100 PBX, the desk phones can be configured with Multiple Appearance Directory Number (MADN). The MADN allows each DN to have more than one line. Currently on some older loads of the DMS-100, desks with MADN Multiple Call Appearance (MCA) cannot be datafilled with Simring. We recommend the use of Key Short Hunting (KSH), which is compatible with Simring, and would act as if the desk has two lines for the one DN. The following steps should be taken to convert from MCA to KSH with Simring: 1. Remove MCA from the DN. 2. Assign a new fake DN to the 2 nd line of the desk phone. 3. Add Simring to the first line. 4. Use KSH for both lines. 5. Remove CFB and CFD voicemail re-direct from the first line. 6. KSH Default should route to a voicemail number, in the event that both lines are busy. 7. Add CFD voicemail re-direct to the 1 st and 2 nd line. 8. Add Number Replacement on the 2 nd line to represent the 1 st DN. This would allow the voicemail system to recognize the correct voice mailbox. The only restriction on using the above method is that if the first line is busy, Simring does not activate. This results in the 2 nd desk line ringing, but the mobile would not.
