Device Limitations and Known Issues This is a list of problems or not supported features when EarthLink has a SIP trunk connected to the Mitel 5000 Communications Platform.

Features Problem Description

Faxing G.711 faxing is possible over the trunk only.

Recommendation: None. EarthLink does not support T.38 faxing.

Calls to “busy” PSTN numbers

When Mitel extension calls to a “busy” PSTN number, the audible “busy” tone is heard almost immediately. However, SIP message “486 – Busy Here” arrives at 5000CP only after 30 seconds. Because of this, forward trunk clearing is impossible until the real SIP message 486 is received. Recommendation: none. Contact EarthLink for further details.

Video Calls Mitel 5000CP does not support multiple m-lines and as such is incapable to process video calls.

Video functionality is unavailable over the ErthLink SIP trunk. Recommendation: none

Reliable Provisional Responses (PRACK)

Mitel 5000 Communications Platform does not support PRACK at this time.

Recommendation: Contact Mitel for further information regarding this feature.

Packetization rate The SIP trunk fully supports only 20ms packets rate whereas Mitel 5000CP supports 20ms and 30ms rates (Audio Frames). Recommendation: In Mitel 5000CP, keep packets rate of 20ms.

Call privacy on outbound calls

There is no way to configure a "classical" privacy in 5000CP (with "anonymous"). If you remove the Calling Party Number from Trunk Group Configuration, EarthLink rejects this call. If you enter e.g. "1111111111", then this call will be accepted and number delivered at far end is "1111111111". Recommendation: Contact EarthLink for further information regarding this issue.

Configuration Notes This section is a description of how the SIP Interop was configured.

Disclaimer: Although Mitel has attempted to setup the interop testing facility as closely as possible to a customer premise environment, implementation setup could be different onsite. YOU MUST EXERCISE YOUR OWN DUE DILIGENCE IN REVIEWING, planning, implementing, and testing a customer configuration.

Mitel 5000 Communications Platform Configuration Notes The following steps show how to program Mitel 5000 Communications Platform to interconnect with EarthLink Service Provider.

Network Requirements • There must be adequate bandwidth to support the voice over IP. As a guide, the Ethernet

bandwidth is approx 85 Kb/s per G.711 voice session and 29 Kb/s per G.729 voice session (assumes 20ms packetization). As an example, for 20 simultaneous SIP sessions, the Ethernet bandwidth consumption will be approx 1.7 Mb/s for G.711 and 0.6Mb/s for G.729. Almost all Enterprise LAN networks can support this level of traffic without any special engineering. Please refer to the 5200 Engineering guidelines for further information.

• For high quality voice, the network connectivity must support a voice-quality grade of service (packet loss <1%, jitter < 30ms, one-way delay < 80ms).

Assumptions for the Mitel 5000 Communications Platform Programming The SIP signaling connection was configured to use UDP on Port 5060.

11-4940-00180 EarthLink

Licensing and Option Selection – SIP Licensing Ensure that the Mitel 5000 is equipped with enough SIP Trunks licences for the connection to EarthLink. This can be verified within the Software License form.

Check the total number of licenses in the SIP Trunk Licences field. This is the maximum number of SIP trunk sessions that can be configured in the Mitel 5000 to be used with all service providers and applications.

Figure 2: Example of SIP Licensing

Creating and Configuring a SIP Peer Trunk Group To support SIP trunks through a SIP trunk service provider, the SIP Trunk Groups folder was added to the SIP Peers folder in DB Programming.

To create a SIP Trunk Group for EarthLink, navigate to System->Device and Feature Codes->SIP Peers->SIP Trunk Groups and right click in the right hand window panel. Then select “Create SIP Trunk Group”. (See Figure 3)

Figure 3: Example of Create SIP Trunk Group

When you create a SIP Peer trunk group without using a template, you must obtain the necessary information from the SIP trunk service provider, and then configure this information in DB Programming.

When Trunk group for EarthLink is been created, we have to configure parameters in Configuration and Trunk Group Configuration nodes.

11-4940-00180 EarthLink

Programming the Configuration settings • Registrar: Although EarthLink’ SIP trunk requires registration, we don’t need to configure

any registration details in Mitel 5000. Instead, all these settings were configured in Adtran IP Business Gateway by EarthLink personnel. Set Enable Registration option to No as shown in Figure 4.

Figure 4: Example of Registrar form

11-4940-00180 EarthLink

• Authentication: In this form, we still need to configure Username and Password for outbound calls as shown in Figure 5. EarthLink should provide Username and Password.

Figure 5: Example of Authentication form

• Keep-Alive: The Keep-Alive option keeps refreshing the NAT bindings for any Firewall/NAT in the path. It also helps in determining whether the SIP peer is reachable or not. Leave the default values here.

• NAT Settings: Specifies the NAT address type. The default is “No NAT or SIP-Aware NAT” (for systems that are using a SIP-aware firewall). If you are not using a SIP-aware firewall, you must change the setting to “Non SIP-Aware NAT”. Leave the default values here.

• Alternate IP/FQDN List: At the time of testing, EarthLink used a single IP address to send SIP messages to the Mitel 5000. Therefore, there is no need to configure any alternative IP addresses or FQDNs.

Click Configuration node (see Figure 6) • IP Address: Indicates the IP address of the SIP peer trunk group. Since we use Adtran

IP Business Gateway as Back2Back agent, we have to configure IP address of Adtran’s LAN interface here.

• Port Number: Indicates the port that the system listens on the system for SIP peer messages. The range is 0–65535. Leave the default value of 5060.

11-4940-00180 EarthLink

• Fully Qualified Domain Name: Indicates the domain name of the SIP peer trunk group. In our test environment, we do not use FQDN. Therefore, leave is blank.

Figure 6: Example of Configuration form

• Call Configuration: Enter the call configuration number in Value field that you want to use with this trunk group. Clicking Call Configuration takes you to the Call Configuration folder where you can add a new call configuration profile or configure the existing profile(s) (e.g. codecs for voice and faxing, DTMF settings, etc. See section Call Configurations). (System->IP-Related Information->Call Configurations-><call configuration number>).

• Operating State: Indicates the operating state of the SIP peer. If required, the status could be changed to “Out-of-Service – Maintenance”.

• Maximum Number of Calls: Indicates the maximum number of concurrent calls that are been permitted towards the SIP peer. This number is not configurable in here and depends on number of trunks added at System->Device and Feature Codes->SIP Peers->SIP Trunk Groups-><SIP Trunk group #>->Trunk Group Configuration->Trunks (see next section for details)

• Use ITU-T E.164 Phone Number: If set to Yes, the Mitel 5000 handles ITU-T E.164 formatted phone numbers as part of the incoming SIP INVITE messages from the SIP peer.

• Static Binding: It specifies whether a static binding exist for the corresponding SIP Peer. If set to Yes, then IP address and listening port for the SIP Peer must be configured. Leave this setting to Yes.

11-4940-00180 EarthLink

11

• Use Peer Address In From Header: In our test environment, we set it to No.

Programming the Trunk Group Configuration properties To program the Trunk Group Configuration properties, navigate to System->Device and Feature Codes->SIP Peers->SIP Trunk Groups-><SIP Trunk group #>->Trunk Group Configuration:

As per Figure 7, we need to configure three most important parameters:

- Day and Night Ring-In Type – in our test environment we configured Single ring-in type with the value of 1310, where “1310” is the extension number where the incoming DID trunk calls are terminated.

- Calling Party Number – is the default calling party number, which 5000CP presents to the provider’s SIP trunk. EarthLink should give this number to you. If this value is missing, EarthLink rejects to process this call. So, insure that this field is not blank.

For the rest of the settings, refer to the DB Programming Help for trunk programming

Figure 7: Example of Trunk Group Configuration

11-4940-00180 EarthLink

Programming the Trunks in Trunk Group Configuration Folder The number of SIP trunks that we create in here will appear as Maximum Number of Calls in the Configuration screen (see Figure 6).

Create the SIP peer trunks as follows: • Navigate to System->Device and Feature Codes->SIP Peers->SIP Trunk Groups-><SIP

Trunk group #>->Trunk Group Configuration->Trunks • Right-click the right pane and the select Create SIP Peer Trunk. The Create SIP Peer

Trunk dialog box appears (see Figure 8). • Select the extension number you want to use for the item in the Starting Extension field.

The recommended range is 94001–94999; • Indicate the number of extensions you want to create in the Number of Extensions field. If

the system is set to have more than one extension, the new trunks will be assigned sequentially to the next available numbers.

• Click OK. For the EarthLink, 3 extensions were created, See Figure 8. The number of available SIP Trunks licenses restricts the number of SIP peer trunks.

Figure 8: Example of SIP Trunks creation

Phone Configurations

Some configuration settings need to be updating for the extensions. In our test environment, when Outgoing key is pressed on the phone, we wanted to direct outbound calls to the EarthLink’ SIP trunk. To do this: • Navigate to System->Device and Feature Codes->Phones-><Phone’s extension

number>->Associated Extension • In right hand pane, select Outgoing Extension and enter the number of SIP Trunk

Group corresponding to EarthLink’ trunk (in our test environment – 92006). See Figure 9 for details.

You can configure a voicemail extension in the same screen.

Figure 9: Configure outgoing extension for the phone

When configuring call forwarding to a voicemail box, it is not enough to create the mailbox and assign it to the phone. You also have to define a Forwarding Path and assign it to the phone. To do this: • Navigate to System->Phone Related Information->System Forwarding Paths • Define at least Forwarding Point 1 for the selected path. In the example in Figure 10, we

defined extension 2502 as the forwarding point for path #3. Extension 2502 is a MAS (NuPoint) server’s voicemail pilot number. We also defined extension 2500 as Forwarding Point 1 for path #2. Extension 2500 represents the pilot number for Basic voicemail (BVM).

11-4940-00180 EarthLink

NOTE: For easier identification later on, we would recommend to enter a text in the Description field as shown in Figure 10.

Figure 10: Example of Forwarding Path definition

Now, when Forwarding Path #3 and #6 are defined, we can assign one of them to the phone: • Navigate to System->Device and Feature Codes->Phones-><Phone’s extension

number>->Forwarding Paths • Right click in right hand pane and select Add to Forwarding Paths List • Select the Forwarding Paths and click Next • Select the required Forwarding Path’s number and click Add Items button • Click Finish NOTE: If you wish to forward unanswered internal calls to the defined Forwarding Point, set parameter Fwd Call Type – IC Calls to “Yes” as shown on Figure 11.

Call Configurations Call configurations define the settings that IP phones and gateways use when connected to calls. You can assign multiple devices to a specific call configuration.

By default, all IP devices are been placed in Call Configuration 1, which is programmable. You do not need to add SIP phones to Call Configurations, because these devices negotiate call configurations before establishing a connection. You can program up to 25 different Call Configurations. Since EarthLink SIP trunk does not support T.38 faxing, we recommend enabling codec G.711U for faxing (see Figure 12 for details). Set Audio Frames/IP Packet to “2” which corresponds to the packet rate of 20ms.

To view the list of IP phones which are currently assigned to the call configuration: • Navigate to System->IP-Related Information->Call Configurations-><call configuration

number> • Click Phones

Figure 12: Call Configuration Options

You can move extensions to this call configuration profile. To do this: • Right click in right hand pane and select Move to Phones List • Select the device type, e.g. 52xx/53xx and click Next • Select extensions that you want to move and click Move Items button • Click Finish

To view and move SIP Trunk Groups to the Call Configuration: • Navigate to System->IP-Related Information->Call Configurations-><call

configuration number> • Click SIP Trunk Groups • Right click in right hand pane and select Move to SIP Trunk Groups List • Select the type, e.g. SIP Trunk Group and click Next • Select the required trunk group that you want to move and click Move Items button • Click Finish
