VoIP has turn into an important a part of an organization’s community infrastructure, and the necessity for educated community engineers with VoIP expertise is ever-growing. Because of the want for skilled engineers Cisco has added the CCNA Voice to their certification applications. Cisco has additionally added two implausible options to their Packet Tracer community simulator utility that when mixed present instructors with the flexibility to create a multiuser VoIP classroom lab atmosphere that requires no further {hardware} outdoors of the community simulator utility. These two options are the flexibility to assist multiuser and VoIP Labs. Different simulator applications like Boson and GNS3 solely assist certainly one of these options internally, however not each options. Boson offers VoIP assist together with VoIP gadgets such because the 7940 IP cellphone however has no multiuser assist. GNS3 has multiuser assist and likewise helps VoIP on the routers and Name Supervisor Categorical (CME) however has no IP gadgets due to this fact requiring you to purchases IP telephones just like the Cisco 7940 which you will discover on eBay for about $75. GNS3 additionally has no configurable switching assist. This in my view provides Cisco’s Packet Tracer a transparent benefit over the competitors.
The important thing to offering a VoIP classroom lab atmosphere is the multiuser capabilities of Packet Tracer. By permitting a number of computers operating Cisco’s Packet Tracer to connect with a simulated WAN atmosphere utilizing a Native Space Community (LAN) and ports offers the scholars the flexibility to construct their very own native labs and join the labs to the simulated WAN as if they had been in an actual world atmosphere, and with assistance from a cheap headset that may truly make cellphone calls to different college students by way of the simulated WAN.
The simulated WAN atmosphere shall be created utilizing Packet Tracer on the instructors laptop and may present a simulated Web with WEB and Mail servers that the scholars can entry and ship e mail as if they’re related to the true Web.
Whereas Cisco’s Packet Tracer doesn’t assist all of the Cisco’s Name Supervisor options Packet Tracer will assist sufficient to indicate the VLAN capabilities of the Cisco 7940 IP cellphone permitting the scholar to create separate Voice and Information VLANs. It’ll additionally permit the scholar to study to configure telephony service and dialing friends. To supply these identical options with actual {hardware} would require two routers such because the 1760V one with CME, two switches 3524 and two IP telephones 7940. This might value about $750 on eBay for every pupil.
