1.0 Introduction

This document will cover the basic setup of the Nortel BCM50 R5.0 and BCM450 R5.0 for us e with the Bell Canada SIP Trunking service.

• Testing was performed in accordance to the Bell Canada test plan and all the core features of the SIP Trunking service were verified.

• The BCM450 configuration detailed in this document was verified in a lab environment with a minimal configuration used to ensure proper interoperability between Bell’s SIP network and the system under test.

DISCLAIMER: The configuration described in this document details only the minimum configuration required for interoperability to be successful; so care must be taken by the network administrator to ensure this configuration is valid for their deployment network, accounting for version differences, and possible feature conflicts with their CPE environment as well. Note all test cases where run BCM450 R5.0 hardware. Minimal testing was performed on the BCM50R5.0 system as the function of the BCM50 R5.0 and BCM450 R5.0 systems are identical this service.

1.1 Prerequisites

This document assumes the reader possesses administrator-level kno wled ge in regard to the deployment and configuration of the BCM line of products and there associated Management tools. Based on that assumption, this document will only cover what is necessary to connect the specified the BCM hardware to the Bell SIP Trunking service. The document does not cover any non-trunk-related configurations or any complex trunk-routing scenarios specific to a given customer deployment scenario.

1.1.1 Required Reading

The reader is urged to consult the Bell SIP Trunking Service Interface Document for more detailed coverage of the content in this guide. The Service Interface Document includes detailed coverage of the SIP –Trunking service parameters, including example SIP messages, full coverage of the production version of the dial-plan, and detailed coverage of codec support and policies for trans-coder invocation.

2.0 SIP Trunking Service Overview

2.1 What is SIP Trunking?

The SIP Trunking Service is a critical element for customers migrating to VoIP. The SIP Trunking Service provides customers with a voice gateway (typically an IP-based PBX) over their data network for calls to and from the PSTN.

An IP Trunk consists of a single virtual voice channel with local calling rights in the rate centre in which it is associated. The terminology used to describe the virtual voice channel is a “concurrent call” (“DS-0 equivalent” is also used sometimes). Customers can buy one or more concurrent calls to enable more than one call to be established simultaneously. Purchasing multiple trunks is referred to as a trunk group, so purchasing a trunkgroup with ten trunks would allow ten simultaneous calls to be carried on at once using that trunk group.

A rate centre represents the local calling area wherein customers can call each other without incurring toll charges. If a customer buys one trunk (one concurrent call) in the Toronto rate centre (416), they have purchased the capability for anyone on their corporate network to make one local call within that rate centre. If the customer places a trunk call to a location that is outside their local rate center, they would be charged for a long dista nce call. Callers in the Toronto 416 calling area must pay long distance to call the 514 rate centre in Montreal, for instance.

5.0 Features

5.1 Features Supported

The following list summarizes the base feature set for Bell SIP Trunking that has been verified on the tested equipment.

• Basic Call using G.729 or G.711ulaw

• Calling Party Number Presentation and Restriction

• Calling Name

• Intra- and Inter-site Call Transfer

• Intra- and Inter-site Conference.

• Call Hold and Resume

• Call Forward All, Busy and No Answer

• Fax using G.711 passthru

• TTY using G.711 passthru

• Outbound calls to IP and TDM networks

5.2 Trunk Group Selection for Originating Calls

The charging model for Bell SIP Trunking service is based upon Bell’s legacy PRI trunk model, and allows a trunk subscriber the ability to purchase trunks that provide local presence in one or more given toll rate centre’s. This implies the need for the subscriber to be able to originate outbound calls on the trunk of their choice so as to minimize the toll charges they would incur placing calls into any rate centre that they do not have a local presence (dedicated trunk) for. For instance, an Ottawa-based trunk subscriber can pla ce local calls to Toronto customers if they have purchased a trunk for the 416 rate centre.

The ability to select an outbound trunk on a per-call basis allows a customer with multiple trunks to originate their call from within a rate centre that is local to the called party. This selection is accomplished through one of the following mechanisms (listed in order of precedence):

* Note currently the BCM does not support trunk group selection within the IP trunk interfa ce via the additions of specific SIP headers as described above, so by default the “No Trunk Selected” mechanism is used.

•

TGRP (RFC 3904)

RFC 3904 describes a standardized mechanism for conveying trunk group selection parameters within ‘sip:’ and ‘tel:’ URLs..

Bell Canada SIP Trunking service expects a trunk group selection to be conveyed in the contact header for calls originating on the PBX and destined for the PSTN. The trunk group parameters detailed below are specific to the Bell Canada SIP Trunking service. These parameters are defined during the service setup process.

Example SIP Header:

• OTG

Contact: <sip:6131112222;tgrp=rate_613;trunk- context=sipt.bell.ca@gw1.example.com;user=phone>

The example shows the trunk selection parameters are to be inserted between the user and domain parts of the contact address, and are semicolon-delimited. In this example, trunk group identified by the label ‘rate_613’ and trunk-context ‘sipt.bell.ca’ are used to route this particular outbound call.

Including an OTG parameter in the From:, P-Asserted-Identity:, or Diversion: SIP header fields will indicate to the SIP Trunking service that the customer wishes to use originate a call within the trunk group specified by the ‘otg=’ parameter. The value of this parameter is defined during the service setup process.

Example SIP Headers: From: <sip:6135604063@company.ca;user=phone;otg=rate_613> P-Asserted-Identity: <sip:6135604063@company.ca;otg=rate_613> Diversion: <sip:6135604063@company.ca;user=phone;otg=rate_613> Each of the header parameters above can be used to specify the trunk preference for this call to

the SIP trunking service. In this example the customer wants the call to be placed using the settings for trunk group 613 (including billing and capacity management).

•

No Trunk Selected

If none of the preceding trunk selection mechanisms are used for a given outbound call, the SIP Trunking service will use the calling party’s default trunk for that call. The default trunk is selected using the identity of the call originator, which is typically specified by the contents of the SIP From: header. If the From: header is encrypted or set to ‘anonymous’, then the service will use the contents of the P-Asserted-Identity: header instead.

6.0 Deployment considerations

• A clear media path from IP sets to the sip trunk interface is required. The IP set determines the available codec used for media exchange.

• Trunk selection for the service is based on the From and PAI headers of the sip message. The headers are configured at a set level. Explicit trunk group selection is not supported on the BCM devices.

• If the call contains both G.711 and G.729 G711 will be used independent of the codec prefe re nce in the SDP to the PSTN.

• Call forwards do not include the original caller display information; instead these calls will appear as if they originated from the set doing the forwarding. When “Forward redirection OLI” is turned off. This feature must be turned on for original call display information to be used.

• Additional licensing maybe required on the BCM to support deployment requirements. To connect the Bell SIP trunks you will need at a minimum the IP Trunk module Auth codes

6.1 Media Codec’s for Bell SIP Trunking

Bell SIP Trunking service provides support for G.711, and G.729 codecs. The G.711 codec is the default for SIP Trunking customers, but they may choose to sign up for SIP Trunking as G.729 subscribers in orde r to take advantage of the bandwidth saving a compressed codec offers them.

The SIP Trunking service infrastructure provides transcoding services to manage and alter the media path for calls where G.729 can’t be supported end-to-end. The transcoder’s intervention allows G.729 customers to view their service as a G.729-only service, and they need not consider the media capabilities of the called party’s device or network, as the transcoder mediates the negotiation if required, and encapsulates any discre pancies between the customer’s codec choice and that of the parties they place calls to, or receive calls from.

NOTE: The only valid ptime value for media codecs on the SIP Trunking service is 20 ms. All supported codecs must abide by this restriction. The ‘ptime is specified in the SDP part of the SIP signaling, which is used to negotiate the media path for each session.

7.0 Required Service Configuration Information

Service domain

This is the domain name used by the service and will be inserted into the To: field of all sip messages generated by the PBX destined for the SIP Trunking interface, and in the From: header of all sip messages destined for the PBX from the SIP Trunking interface. The service domain for Bell SIP Trunking service is siptrunking.bell.ca

PBX domain

The PBX domain is the domain name that will be used by the SIP Trunking service to resolve the IP address of the customer PBX that is using the SIP Trunking service. This domain will be present in the To: header of all SIP messages generated by Bell SIP Trunking service to direct inbound calls to the customer’s SIP trunks. This PBX domain is also expected to be the domain presented in the From: header of SIP messages entering the SIP trunk from the customer PBX. An example of a PBX domain specification would be: ‘pbx1.customer.com’

Service IP address

The service IP address will be supplied to the customer by Bell. The service address will be the IP address (or addresses) of the customer-facing SIP trunk interface(s) on Bell’s Session Border Controller(s).

PBX IP address

The IP address of the customer’s PBX that inbound calls will be directed to. The customer’s PBX domain must be resolved to this address when an inbound call is processed by the SIP Trunking service.

Authentication Credentials

This will be the authentication credentials used to authenticate SIP invite messages sent to Bell. This will consist of a user and password

8.0 SIP Trunking Dial Plan Overview

The SIP Trunking service will accept call requests with destinations according to the North American Number Plan (NANP: http://en.wikipedia.org/wiki/North_American_Numbering_Plan) If the service receives a request for a destination number that is not in service or has a malformed number, a proper announcement treatment will be applied.

** Please note that the service will accept 10 digit and 11 digit call requests for local and long distance calls. Depending on the purchased rate, long distance charges may apply. The following list sh ows a nonexhaustive dial plan example we used in our testing

• 10 Digits and 11 Digits for Local and Long Distance Call (long distance ch arge may apply)

• 0+10D Call (operator assistant NA LD Call)

• 01+International NDC (from 8 to 35 digits, Operator Assistant International Call)

• Toll Free Call 1-800,1-888,1-877

• 011+ International Call

• 101+xxxx+NDC call(from 13 to 40 digits, Casual Dial Call)

• 911

• 411, 611, 711, 211, 311, 511, 811

• 1-xxx-555-1212

• 310-xxxx Call

• 1-900 and 1-976 Call

9.0 Configure DNS (Optional)

There are two requirements for name resolution to support SIP Trunking calls. They are sum marized briefly below. For more detailed information, please refer to the SIP Trunking Interface Document.

9.1 Bell resolves PBX domain

• A DNS resolution is needed for SIP trunking to reach the PBX. This DNS resolution can either be managed by customer DNS server or managed by Bell Canada.

• If Managed by Bell Canada the PBX destination IP address(es) needs to be provided to Bell Canada.

• If Managed by the customer, the customer needs to provide DNS access for the SBC to query the PBX

domain. The domain is agreed upon during service setup and must resolve to the PBX IP address via an SRV and A records.

9.2 PBX resolves Bell service domain

• Bell Canada provides redundant connections for the service. To provide redundancy the customer PBX

can utilize DNS SRV records to resolve 1 or more Service interface IP addresses. These IP addresses are provided during service setup

Select Telephony Æ Sets Æ Active Sets Æ Line Access Æ Line assignment

The DID phone number associated with the Bell SIP trunk that is assigned to the BCM, has to be associated with a BCM “Target” line. The BCM Target line can be assigned to an individual DN/set or group of set(s) and all calls to the DID number will be routed to those phone(s) respectively. Note

: All calls to the DID phone number associated with the Bell SIP trunk assigned to the BCM, can also be answered by the Auto Attendant (AA) and from there, a DN/extension number can be entered to reach a set on the BCM

What is important in this area is to “Add” and “Assign” a “Target Line” number to the DN/set and enter the DID phone number into the Pub Received phone number area. Add the Pub OLI 10 Digit phone number to the DN/set. This is set to the 10 digit outbound phone number that you want to display when a call leaves the BCM toward the SIP trunk.

This can be done in several ways; Click on Add, enter Target Line number and select “Appear & Ring” and then select Check box Caller ID Set.

Add the Pub. Received # : This is the phone number assigned to this DN/set on inbound calls and will cause the DN/set to ring. Pub OLI. : This is set to the 10 digit outbound phone number that you want to display when a call leaves the BCM toward the SIP trunk.
