IntroductionHP ProCurve Networking and Avaya Unified Communications Solutions provide compelling value for companies seeking best-in-class Branch to Enterprise IP Telephony and Unified Communications solutions. Avaya and HP ProCurve deliver a number of unparalleled and flexible solutions for enterprises with small to large remote sites.

Customers are looking for communication solutions that lower costs, accelerate business growth and mitigate risks. Improving employee productivity and customer service are important elements to achieve these business objectives. Avaya and ProCurve have certified a joint IP Telephony solution consisting of HP ProCurve switches and Avaya Aura™ Communication Manager, Media Gateways and IP Phones to serve as the key foundational elements of a powerful Unified Communications portfolio.

This document describes a typical Enterprise VoIP use model using ProCurve and Avaya products. Results are documented from a series of tests designed to verify interoperability and system functionality such as enterprise grade voice quality, configuration and network authentication.

Solution architecture DescriptionHP ProCurve and Avaya bring together the best-in-class communication products from Avaya, the market leader in Unified Communications and the worldwide leader in Total PBX, which includes IP telephony, TDM and hybrid systems , with highly reliable and secure Adaptive Networking products from HP ProCurve. This solution provides for a feature rich and consistent communication experience across the entire enterprise organization allowing for improved worker productivity, simplified system management and reduced total cost of ownership. Local survivability is maintained in this sample topology configuration that continues to provide telephony service in the event of any WAN connectivity failures.

These VoIP solutions leverage lower cost WAN connectivity compared to standard PSTN given the shared voice and data infrastructure. They also enable Unified Communication applications to seamlessly integrate voice, video and data traffic over a common converged IP network to unify all forms of voice, video, instant messaging and presence to transform businesses communications, reduce costs and improve productivity.

Several industry standard protocols are leveraged to improve interoperability such as 802.1X authentication, LLDP-MED for IP phone auto-configuration and 802.1p/DSCP for QoS packet prioritization to ensure enterprise grade voice quality.

Typical topologiesThe topology shown in figure 1 represents an Enterprise deployment with a consolidated Data Center serving multiple campuses and branch offices. The communication features and user data would be managed centrally with survivable gateway’s each in critical site. The amount of survivability could be scaled from full functionality to basic call plan features depending on the need of the remote site.

Another typical topology is for mid-sized companies with just a few smaller separate sites. In this case it makes less sense to have a centrally managed calling plan but rather each site is managed independently as shown below. In this case VoIP could only be used intra-site and all voice inter-site traffic could utilize the PSTN or SIP Service Provider trunks.

Test resultsAll configuration tests successfully passed their objectives

For the Voice Quality Test, the following test results were achieved with background traffic to simulate an oversubscribed network. The test equipment used measured actual analog voice quality from phone endpoint to phone endpoint and truly validated the codec (encoding and decoding the analog voice to/from digital IP data) as well as the entire network path between the endpoint devices.

Test topology

11

* maximum unpaired G.711 codec MOS is 4.4

MOS: Mean Opinion Score provides a numerical indication of the perceived quality of received media after compression and/or transmission. Values above 4.0 are considered “toll-grade” voice quality.

PESQ: Perceptual Evaluation of Speech Quality is a family of standards comprising a test methodology for automated assessment of the speech quality as experienced by a user of a telephony system. It is standardized as ITU-T recommendation P.862 (02/01).

PSQM: Perceptual Speech Quality Measurement is a computational and modeling algorithm defined in ITU Recommendation ITU-T P.861 that objectively evaluates and quantifies voice quality of voice-band (300 - 3400 Hz) speech codecs.

Delay: Represents the total delay from initiating Phone to receiving Phone. Accounts for Gateway jitter buffer/decoding and network delays. A maximum end to end delay of less than 150ms is recommended to achieve “toll-grade” voice quality.

Design considerationsThe following best practices were followed, in order for voice and data traffic to behave optimally on a shared network:

•Separatevoiceanddatatraffic–TheuseofavoiceVLANsegregatesvoicefromdatatraffictoprotectIPphones from data broadcasts and provides an easy to deploy mechanism to prioritized voice traffic higher than the data traffic, throughout the network topology

•EnforcedconsistentQoS(QualityofService)policiesend-to-end–Allswitchesandrouterswithintheenvironment must participate in the QoS infrastructure, to ensure voice is properly prioritized ahead of data traffic throughout the network topology

•WANlinksconfiguredforvoicetraffic–SufficientbandwidthfortherequirednumberofconcurrentVoIPcallsneeds to be provisioned on the WAN links in order to establish and ensure an appropriate SLA (Service Level Agreement) with the service provider

Configuring the WAN interfaceIn this example, the link between the main office router and the remote office router was a PPP connection.

7302main (config)# int t1 3/1

7302main(config-t1 1/1)# tdm-group 1 timeslots 1-24 speed 64

7302main(config-t1 1/1)# no shutdown

7302main(config-t1 1/1)# interface ppp 1

7302main(config-ppp 1)# ip address 10.10.2.251 255.255.248.0

7302main(config-ppp 1)# bind 1 t1 3/1 1 ppp 1

Configuring QOS and ACLsTo provide priority to the voice traffic, the main office router had a QoS policy defined to affect only the voice traffic.

First, an ACL (access control list) was used to identify the voice traffic between the two voice VLANs – UDP for call traffic and TCP for control traffic.

7302main(config)# ip access-list extended Avaya

7302main(config-ext-nacl)# permit udp 10.54.8.0 0.0.7.255 10.84.8.0 0.0.7.255

7302main(config-ext-nacl)# permit tcp 10.54.8.0 0.0.7.255 10.84.8.0 0.0.7.255

Next, a QoS map was used to apply the QoS policy to the traffic identified by the ACL.

7302main(config-ext-nacl)# qos map AvayaQoSMap 1

7302main(config-qos-map)# match list Avaya

7302main(config-qos-map)# priority 256

7302main(config-qos-map)# set dscp 46

With the QoS map defined, it was applied to the frame interface.

7302main(config-qos-map)# interface ppp 1

7302main(config-fr 1)# qos-policy out AvayaQoSMap

7302main(config-fr 1)# no shutdown

Configure Avaya gateway & serverThe G450/8300 was configured to handle voice traffic for VoIP phones on the network. Defining the setup and configuration for the G450/8300 is beyond the scope of this document. For further information see section 5.2
