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. Supported Versions This document addresses the required configuration changes on TDM PBXs (PBXs that do not support SIP trunk or SIP line interfaces) to enable integrated operation with the Accelerator. SIP to PRI conversion The Accelerator uses the SIP protocol for call control of the calls made and received by Accelerator subscribers. A SIP/PRI gateway is therefore used to provide the necessary inter-working function for these releases. This requires the provisioning of PRI trunks on the TDM PBX along with translations and routing as described in section TDM PBX Integration Requirements. Simultaneous Ringing (SIMRING) If the Accelrator mobile is to be used in conjunction with a desk phone (or soft client), the TDM PBX must support a SIMRING feature that allows an incoming call to ring one or more devices simultaneously. TDM PBX Dependencies License Key To use the Accelerator with TDM PBXs, the following software licenses may be required on the PBX: One SIMRING license per Accelerator subscriber who wishes to use both their desk phone (or soft client) and their Accelerator mobile Trunking Interfaces To use the Accelerator with TDM PBXs, PRI trunks are required on the TDM PBX to interwork with the SIP/PRI gateway.

TDM PBX Integration Requirements This section describes the requirements for the Accelerator to integrate with a TDM PBX. The following checklist itemizes the items required for integration: SIP/PRI Gateway (e.g. Audiocodes Mediant line of gateways) Available PRI trunk ports on TDM PBX SIMRING feature enabled on TDM PBX Provisioning of translations capability Pilot Numbers and Accelerator alias numbers Provisioning of PBX and subscribers on Accelerator Enterprise solution Installation of SIP/PRI gateway The SIP/PRI gateway needs to be installed in a location accessible by the PRI spans from the TDM PBX and by an Ethernet connection to a network segment routable to the Accelerator Enterprise servers. The PRI spans are connected between the TDM PBX trunk peripheral and the SIP/PRI gateway. Tango Networks has completed interoperability testing with Mediant AudioCodes 2000 gateway, net VX gateway, and AdTran gateway. Please check with Tango for additional gateway interop results. Translations Provisioning Pilot numbers need to be allocated to route calls into the enterprise for handling by Accelerator. Translations need to be set up to route these inbound calls to the pilot numbers over the trunk that is connected to the PRI gateway and then to the Accelerator. Alias numbers 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 trunk to the Accelerator. Configuration of SIMRING feature The SIMRING feature allows an incoming call to ring a group of directory numbers simultaneously. To support the Accelerator, the SIMRING feature is configured for each Accelerator subscriber s desk phone to enable simultaneous ringing of the user s desk phone and an Accelerator alias.

Accelerator Provisioning Note: 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 TDM PBX in the Accelerator (required). 2. Define the TDM PBX in the Accelerator (required). Define a SIP Trunk Group/Trunk to route traffic from the TDM PBX to the Accelerator (required). 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. Define the Call Service Pilot Numbers (required if using the Call Move service)- Used for the Call Move service. Define Least Cost Route (optional) information for SIP trunk traffic from the Accelerator to the TDM PBX (optional). 3. Define the Enterprise Ranges used in the enterprise. 4. Define the Carrier Gateways (required if your enterprise routes calls between the wireless carrier and the Accelerator). 5. Define the Voice Mail system used with the TDM PBX (recommended). 6. Define Subscriber Dial Plans in the Accelerator (required). 7. Define Accelerator subscribers that use the TDM PBX (required). The steps below describe the unique configuration areas needed to integrate the TDM with the Accelerator. Refer to the Accelerator Provisioning Guide for a comprehensive explanation of Accelerator provisioning. Voice Network : PBX/Trunk Dial Plan 1. Add Trunk Dial Plan (required) There are no unique configuration items for Trunk Dial Plans and the TDM PBX. Refer to the Accelerator Provisioning Guide, Voice Networks, PBXs, Add Trunk Dial Plan section. 2. Add PBX (required) Refer to the Accelerator Provisioning Guide, Voice Networks, PBXs, Add New PBX section. Add Trunk Group/Trunk (required) o A SIP trunk is created to route traffic from the Accelerator to SIP PRI Gateway associated with the TDM PBX. Multiple trunks to different gateways may be created for scalability/redundancy reasons. The April 2014 CONFIDENTIAL Page 6 of 16

o o Accelerator will randomly select trunks in a trunk group on a per-call basis and will route advance among trunks in the trunk group if a trunk is unavailable. When provisioning Trunk Groups/Trunks in the Accelerator. Trunk Group Request URI parameters are not used by the TDM PBX and therefore do not need to be provisioned. Refer to the Accelerator Provisioning Guide, Voice Networks, PBXs (Add/Modify), Add Trunk Groups/Trunk section. Add Pilot Numbers (required if your enterprise intends to route Pilot DNs through the TDM PBX) - No unique configuration areas required for provisioning Pilot Numbers to the Accelerator. Refer to the Accelerator Provisioning Guide, Voice Networks, PBXs (Add/Modify) section. Add Call Service Pilot Number (required if using the Call Move Service). No unique configuration items for Call Service Pilot Numbers. Refer to the Accelerator Provisioning Guide, Voice Networks, PBXs (Add/Modify) section. Add Least Cost Routing (optional) in the Accelerator for the TDM PBX. No unique configuration items for Least Cost Routing. Refer to the Accelerator Provisioning Guide, Voice Networks, Least Cost Routes, Add Least Cost Routes section. Voice Network : Extension Ranges 3. Add Extension Ranges (required) No unique configuration items for adding an Extension Range. Refer to the Accelerator Provisioning Guide, Voice Networks, Extension Ranges, Add New Extension Ranges section. Voice Network : Carrier Gateways 4. Carrier Gateways (required if your enterprise routes calls between the wireless carrier and the Accelerator) If your enterprise intends to use an SBC or Carrier Gateway between the carrier and the enterprise, then add a Carrier Gateway. Be sure to supply the Outbound Domain as required by the add Carrier Gateway page. If you are using Pilot numbers to route calls from the wireless carrier to the Accelerator using the Carrier Gateway, provision the Pilot Numbers on the Carrier Gateway s main page. Depending on your configuration, the Pilot numbers here may need to be E.164 routable. Add Trunk Groups/Trunk (required if using a Carrier Gateway) o o Host Address, Port and Transport Type should match the value of the carrier s SIP endpoint. If the hostname is entered, the Accelerator queries the DNS server for the associated DNS SRV records. This allows for redundancy and/or load balancing based on the DNS SRV records if the customer has deployed multiple TDM servers. Refer to the Accelerator Provisioning Guide, Voice Networks, Carrier Gateway (Add/Modify), Add Trunk Groups/Trunks section. Trunk Group Request URI parameters are normally not required by most SIP endpoints, however, consult your carrier s instructions. Add Least Cost Routing (optional) - No unique configuration items for Least Cost Routing. Refer to the Accelerator Provisioning Guide, Voice Networks, Carrier Gateway, Least Cost Routes, Add Least Cost Routes section. April 2014 CONFIDENTIAL Page 7 of 16

Accelerator PBX Level 2 Integration Table 2 Accelerator PBX Level 2 Integration Feature Support Comments Call Accounting Codes No Call Coverage/Hunt Groups Call Line Identification Restriction (CLIR) (Mobile) Call Pull (Desk->Mobile Call Move) No Call Push (Mobile->Desk Call Move) Class of Restriction (COR) (PBX) No Class of Service (COS) (PBX) No 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. Call Line Identification Restriction (CLIR) (Mobile) - Allows the user to restrict their calling line information from being displayed to the called number. The Accelerator supports restriction of calling line identification from mobile phones. Enterprise identity will be replaced; however restriction code will be preserved. Call Pull (Desk->Mobile Call Move)- Allows a subscriber to move a phone call between the desk phone and the mobile phone. Feature is invoked from the mobile phone. Call Push (Mobile->Desk Call Move)- Allows a subscriber to move a phone call between the desk phone and the mobile phone. Feature is be invoked from the mobile phone. Class of Restriction (COR) (PBX) - Defines the restrictions that apply when a user places or receives a call. The Accelerator supports COR for mobile originated calls. Class of Service (COS) (PBX) - Allows or denies user access to some system features. The Accelerator supports COS for mobile originated calls over SIP lines. April 2014 CONFIDENTIAL Page 12 of 16

Appendix A: Multiple Call Appearance for Nortel DMS-100 PBX For a Nortel 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: 6. Remove MCA from the DN. 7. Assign a new fake DN to the 2 nd line of the desk phone. 8. Add Simring to the first line. 9. Use KSH for both lines. 10. Remove CFB and CFD voicemail re-direct from the first line. 11. KSH Default should route to a voicemail number, in the event that both lines are busy. 12. Add CFD voicemail re-direct to the 1 st and 2 nd line. 13. 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.
