Introduction
The purpose of this document is to provide a configuration guide for an Alcatel-Lucent OmniPCX Enterprise interconnected to the public Network through a PAETEC SIP Trunk (LPG Platform). The architecture and configuration described in this document is based on validation test that took place at PATEC Labs in Houston, TX between the Alcatel-Lucent OmniPCX Enterprise Rel 9.0 and PAETEC SIP Trunk. The document also includes the limitations identified during the validation test. PAETEC Configuration & Support PAETEC will configure SIP trunks on its network and provide customers with IP addresses of SIP Proxy, and phone numbers assigned to customers before scheduled service activation date. SIP trunks are offered through MPLS connections with proper QoS to guarantee the security and quality of voice traffic. MPLS configuration will be done by PAETEC throughout its network and all the way to the CPEs provided by PAETEC. If you are in need of technical support for PAETEC’s Dynamic IP SIP Trunking, please contact our Customer Care department at 877.340.2600 or
[email protected]. When contacting Customer Care, please include the customer account number.

A-L Call Server
The Alcatel-Lucent OmniPCX Enterprise (OXE) used for carrying the SIP trunk test consisted basically of: - One Common hardware shelf MR3 equipped with one Call Server (CPUA), one GD (with MADA-3 daughter card), one MIX board that included 4 Z ports (for analog phones and faxes) and 8 digital interfaces (for proprietary AlcatelLucent digital sets). A Gateway Applicative interface (GA) equipped with a MADA-3 daughter board was also included in the MR3 shelf (for additional compressors if needed). A PRA T1 (for a North America ISDN interface) and APA8 (for analog trunk interface) were also installed in this MR3 shelf). - A second Common hardware shelf MR1 equipped with a second Call Server (CPUB) was installed to ensure redundancy. 4

- Both CPU’s (A and B) were configured in Spatial Redundancy (over 2 separate IP subnets : 10.1.x.x and 10.2.x.x) with CPU domain address defined as: oxe.PAETEC.net ; DNS SRV was used for address resolution (as it is mandatory to use DNS to resolve the OmniPCX Enterprise CPU address in case of Spatial redundancy and not using the IP address directly). There are 2 IPTouch phones (4038) and 2 IPTouch phones (4028) connected to the OmniPCX Enterprise on the LAN.

SIP Trunk
The PCX configuration for SIP trunking consists of the following parameters: 1 – SIP Trunk Group By Defining a trunk group with virtual accesses used for the SIP calls. Basically, it determines the number of channels available for SIP communications (i.e. number of simultaneous calls). 2– SIP Parameters Define the SIP specific parameters, such as SIP Internal Gateway, SIP Proxy, SIP External Gateway and trusted IP addresses. 3– ARS and Discriminator Define the parameters that allow the users to make and receive calls on the SIP trunk. Comprises the configuration of Access prefix, ARS tables, Dialing discriminator, DID translation, NPD. The following pages contain snapshots (mgr tool) of the PCX configuration related to the SIP trunk implementation. The most relevant parameters are highlighted. 4.2.1

SIP External Gateway
The SIP External Gateway is used Inbound and Outbound SIP calls. For Inbound calls, It is a must (as per the OXE requirement) to define an External Gateway for each IP address of fqdn on the received SIP messages (either in the P_Asserted_Identity or the From objects). Otherwise, Inbound calls will not be routed in by the OXE. The parameter SIP Remote Domain should include this IP address or the fqdn of the SIP SBC. During the validation test with PAETEC, all Inbound calls and Ounbound calls were going through the SBC with the IP address 10.1.3.10 from which SIP messages were received (either in the P_Asserted_Identity or in the From header) was defined as External Gateway for Inbound calls and Outbound Calls (Gateway Id 1) 16

Note: The OmniPCX Enterprise continuously monitors the connectivity to each Gateway by managing the parameter Supervision timer. The default value of this parameter is 0 (which means that the OmniPCX Enterprise does not check the status of the Gateway), once this parameters is managed to a value (in seconds), the OmniPCX continuously checks the connectivity by the end of the interval and puts the link out of service once the connectivity is lost. The link is put back in service once the connectivity is found back alive.

ARS and Discriminator
PAETEC required 10 digits dialing for local and long distance call and open dialing for International calls. By default, the discriminator used is 0 for external calls using the SIP Trunk Group. When a user place an external call using the ARS Professional Trunk Grp Seizure prefix “9”, depending on the number on the dialed number and ARS list is chosen as per the list below. Each ARS list has only one route (only route ID 1) which uses the Trunk Group ID 10 and the SIP External Gateway 1 (using the dialing command table. The ARS tables used are: ARS 0 Æ for international calls ARS 1 Æ for long distance calls ARS 4 Æ for calls to 911, 311, 411 & 711 The Dialing Command Tables used are: Table 1 Æ for ARS 0,1 . Dialing sequence = “I”, external SIP gateway = 1 Table 2 Æ for ARS 4. Dialing sequence = “9I”, external SIP gateway = 1 4.5.1
NPD
The ARS tables use NPD 33 which is configured as below. The NPD configuration can be reached under /Translator/External Numbering Plan/Numbering Plan Discriminator (NPD); Choose Review/Modify or Create (if you are creating it); Enter Description Modifier Id = 33 (in case of Review/Modify)

Summary of Test Results
5.1
Summary of Test Plan Results
A comprehensive validation test plan has been performed including: -
Testing General call Processing Testing Basic Call Failures (extensions busy) Testing the Outgoing Dialing Plan Testing DTMF Detection Testing Call Transfers scenarios Testing Call Forwarding scenarios Testing Calls on hold Testing Call Waiting Testing 3 way-calls Testing PBX Voice Mail Testing faxes Testing redundancy and call hold
The test plan has revealed the limitations and anomalies in the next sections
5.2
OmniPCX Enterprise limitations
The following are the limitations in the OmniPCX Enterprise: -
The OmniPCX Enterprise does not support Fax over G-711. It only supports T-38 protocol. When the OmniPCX Enterprise local User transfers an incoming or outgoing call to another external party. The display on this external party will always show the Number of the local user and not the external party he/she is connected to. The OmniPCX Enterprise does not support feature codes on SIP Trunk (Not needed as features are available locally on the PBX)
