ABC High School VoIP Solution Implementation

Requirements Required To Setup a VoIP Solution Both Software and Hardware Equipment

ABC High School is a private college that delivers education to students from years’ 8 to 12. The campus sits on approximately 5 hectares of manicured grounds, 6 kilometres from the CBD of Adelaide. It consists of a large two-story building containing the majority of the classrooms (22) and administration offices, a dedicated music and arts suite with two classrooms, a resource centre, and an indoor gymnasium containing two full sized basketball courts. There is also a large outdoor oval, tennis courts and practice cricket nets.

The school has a modern approach to education and focuses on the use of technology in the classroom. All students have their own iPads and are used daily in a variety of subjects including science and maths. These are connected to the schools’ wireless network which has recently been upgraded to cover the majority of the campus and support the device density in each classroom. In addition there are 2 purpose built computer rooms located in the resource centre containing 30 modern PCs each, and 4 trolleys of 40 wireless laptops which can be borrowed on an ad-hoc basis for classroom use. The students also have access to 6 printers and photocopies located throughout the campus.

The campus network has just undergone a major refresh which includes a replacement of all existing networking hardware, excluding wireless. The new network delivers 10Gb interconnects and 1Gb to all end devices though a combination of both OM1 and OM3 fibre for vertical cabling and CAT5e and CAT6 for horizontal cabling. The schools’ WAN has also just been upgraded from a 20Mbps to 100Mbps to support the increased traffic due to the iPad usage. Both the logical and physical diagrams have been included in this case study for your reference and should be accurate and reflect the recent changes.

The school currently has a 10 year old PBX connection which is becoming ever difficult to upgrade and maintain. It currently consists of the following components:

• 1 x Ericsson 50 PBX

• 1 x Reception handset that provides the ability for call forwarding, call holding, directory lookup and night mode.

• 30 x basic desktop phones with caller ID

• 6 x wireless antennas with school building and courtyard coverage for 4 cordless phones

• 10 x external lines bound to 1 incoming number (Reception)

• 10 x external line bound to 1 incoming number (Management x 5, IT administrator, Finance, Canteen, Gym, Resource Centre)

• Incoming calls are supplied via an E1 connection from a telco.

As the school wishes to install handsets in each classroom, the current PBX does not have the handset capacity. This combined with the age of the current PBX, it has approved the finance and installation of a CISCO VoIP solution to be rolled out throughout the school.

The Voice over IP Project must meet the following requirements:

1. The reception desk must have a physical phone capable of handling several incoming calls, place calls on hold, internal transfer and at least 20 speed dials.

2. Maintain all existing desk phone (30) capabilities.

3. Maintain the cordless phone functionality throughout the school and courtyard; supply of 4 compatible cordless phones

4. Maintain the existing single FAX line.

5. Maintain existing phone number structure – 2XXXX.

6. All classrooms (22) to have a physical phone capable of internal calls and emergency.

7. Boardroom style phone to support a table of 10 people.

8. Install softphones on a variety of devices including android and Windows PCs.

9. All phones to have the option of speaker phone.

10. Provide the user of the phone with a directory of all internal phone numbers.

11. Message bank for all phones and the ability for the messages to be emailed to inboxes.

12. CallerID on all handsets

13. Messages on hold when a call is put onhold; this message must be able to be updated by staff at the school

14. External direct dial in for reception (x10)

15. External direct dial in for management (x5), IT, Finance, Reception, Canteen, Gym, Resource Centre (10 lines)

16. Although not required at this stage, have the ability to be configured for SIP connection to an external SIP provider.

17. Must not interfere with the schools’ monitored alarm system.

18. Must not interfere with the schools’ emergency lift phone.

Additional questions or clarification regarding the requirements can be posted on the discussion board on the course website.

This assignment has two major deliverables:

1. A list of hardware and/or software which will need to be purchased by the client.

2. A technical installation guide that will assist an IT administrator to install this new technology.

For the first deliverable, you need to research what technology is available that will meet the requirements of the customer; keeping in mind the customer has asked for a CISCO VoIP implementation. You are then to provide a complete list of equipment to be purchased and provide an estimated price. Please ensure this equipment will fully function with the existing network equipment.

In the second deliverable, you need to produce a detailed step by step guide on how to install and configure the hardware and software you have recommended. Please ensure the guide covers phone installation, any additional networking hardware and/or software installation, configuration information for the telephony service, modifications required to the existing networking configuration.

ABC is a learning institution that simply provides education to students from the year range of 8 to 12. The school consist of two large story building containing a major classroom of 22 and administrative office. They also have assigned two classes that are dedicated for music and arts, a resource room and an indoor gymnasium containing two full size basketball courts (Blumhardt, & Smith, 2009). The school on the other hand plans to shift their current method of education to and focus on the use of equipment inside the classrooms. All learners basically will have their own iPad and on various subjects they are required to use it such as mathematics and science. ABC learning facility also have a wireless networking system that has been upgraded through the entire campus and simply supports the density in each and every classrooms.

Furthermore there are 2 reason fabricated PC rooms situated in the asset focus that containing 30 present day 5 the age PCs each, and 4 trolleys of 40 remote PCs which can be obtained on a specially appointed reason for classroom utilize (Cole and Rosenbluth, 2011)). The understudies additionally safe house essential access to 6 printers and photocopies situated all through the grounds.

Integration of the new system that is the VoIP solution will help to enhance the communication in the way that people interact in the network. Also learning can make high ends of the technology and use it to its advantage. In this instance the upgrade can improve and facilitate long call time and the connectivity does not interfere with any normal running function of the organization (Sun and Ifeachor, 2014). In the ip phone connectivity it can be able to display the caller id and on all the handset and also be able to provide the user with all the internal phone book for all the users in the network and also not to forget all the external phone calls are directed to the reception whereby all the internal direct call for the management, IT, Finance, Reception, Canteen, Gym and resource center are able to memorandum bank for all the phones and the capability for the for the message to be dispatched to the inbox.

In a switched network, Virtual Local Area Network is simply considered as logical segment, is simply consist of several attributes such as the physical LAN. They also partition the devices into categorized and segmented broadcast domains and layer 3 subnets (Dooley, & Brown, 2009)). Devices in a simple and dedicated Vlan can interact without physically routing devices to communicate with each other. They offer efficient use and benefits significantly in terms of bandwidth flexibility, performance and security.

As for many companies and organization it is easier to acquire additional Local Exchange Carrier that has creatively features. The following features are include a few of commonly used functions:

• Call waiting – Notifies someone who has already laid up a call
• Call Forwarding – enables the subscriber to forward incoming calls
• Tree – way calling – enable conference calling

The use of continuous Network subnets will ease the use of Route Summarization Link state Routing protocol OSPF will be configured in the network to provide a fast convergence and good scalability (Hares, Chen, Lee, & Manghirmalan,2014). NAT will be implemented to permit access to the DMZ to outside users.

The switch mode made access command is under to change the operation mode of the port from dynamic (Default) to access that ensures the port belongs to and carrier traffic from only one Vlan (Leung, 2012). A port in this mode can also be used to connect end devices only.

The other mode that is trunk can carry traffic from another Vlan’s. Trunk Mode is the one you configure for that port connected to another switch. The dynamic mode allows the port to become an access port when connected to another switch (Zhang, Lundin, and Kleijn, 2008).

“Switch Port Access Vlan [Vlan id]” command binds the port with the Vlan.

1. Specify Vlan number and name 

Switch (config) #Vlan [number] eg.vlan 2

Switch (config-Vlan) #name [word] e.g.

       #name admin

2. Assign Switch port to the Vlan 

Switch (config) #int range type/start num/end num. e.g.

#int range fa0/1-20 (For multiple ports then)

#int range fa0/1 – single port

Switch (config –if) #switch mode access

Or

Switch (Config- if- range) #switch port mode access;

Then

Switch (Config-if) #Switch port Access Vlan [Vlan-id]

Or

Switch (Config- if- range) #Switch port access Vlan [Vlan-ID]

A Virtual Local Area Network is defined to as a switched segment in a switched network in an attribute such as physical LAN. They also partition the devices into categorized and segmented broadcast domains and layer 3 subnets (Vuong & Singh, 2013). Devices in a simple and dedicated Vlan can interact without physically routing devices to communicate with each other. They offer efficient use and benefits significantly in terms of bandwidth flexibility, performance and security.

Inter Virtual Local Area Network (Vlan) routing is simply supported by the switch that basically runs enhanced multilayer image EMI software. One can ideally restrict the communication between VLAN with use of access lists.

There several steps that needs to be made while configuring the VLAN routing:

1. First one needs to enable IP routing in the switch
2. Create a Virtual local Area Network

• Assign the associated switch parts to specified VLANs

1. Assign the IP Address to the Vlan’s

The most commonly used is the layers 2 switching where you configure the LAN on the layer 2 switch and one needs to communicate on the needs a layer 3 switch that consist of a router.

This simply show the number of vlan present in the switch and the configuration.

Conclusion

Voice in the PSTN is a pool of different communication technology that have been I constant change of state sine the innovation. The technology required to enable true multimedia conversation on a daily availability. The telephone communication is taking a different stunt and is moving towards new and different models and will soon be able to bear multimedia conversation.
