Portfólió

A VoIP readiness assessment determines whether a particular network is ready to handle voice over IP (VoIP) in its present configuration. Network readiness was analysed and evaluated for VoIP and video deployments using different tools.

The deployments were determined by: network requirements (switching and routing readiness, bandwidth, latency, jitter, loss, etc), QoS, characteristics of VoIP and Video traffic, security policies etc.

During the assessment, several tasks were performed: compiled an inventory of devices and links on the network, analyzed the configuration of devices discovered during the inventory, monitored the utilization of selected devices and links, modeled link capacity based on the bandwidth required for VoIP calls, evaluated the quality of simulated VoIP calls.

Network Readiness Assessment for VoIP and Video Deployments

The security designs were based on Firewalls (ASA55XX, IOS Firewall), Intrusion Prevention Systems, Content Security and Control Security Services Modules, Proxies, VPN technologies (Site-to-Site, Remote Access, SSL/Anyconnect VPN), etc.

The security strategies were implemented at every layer of communication, from layer 1 (physical security) to application layer.

Prior to implementing the security strategies thorough security audits and vulnerability assessments were made using different tools such as: Nessus or OpenVAS.

Network Infrastructure Security

Designed and implemented a campus network infrastructure.
Each branch office was connected to the enterprise network over VPN. On each site an ASA5505 was deployed.

High availability and QoS strategies were implemented at the enterprise network: HSRP, Etherchannel, Stacks, DSCP, etc

Network Infrastructure - Campus Network

Designed and implemented multi and single-site infrastructures with centralized call processing.

The single-site model consists of a call processing agent cluster located at a single site, or campus, with no telephony services provided over an IP WAN. Calls beyond the LAN or MAN use the public switched telephone network (PSTN).

The multi-site model with centralized call processing consists of a single call processing agent cluster that provides services for many remote sites and uses the IP WAN to transport Cisco Unified Communications traffic between the sites. The IP WAN also carries call control signaling between the central site and the remote sites.

Components used in both designs: Cisco Call Manager (7.x/8.x), Cisco Call Manager Express (7.X/8.X), UC500, Voice Gateways, Analog Devices (VGs/ATAs), IP Phones, etc.

At each site different high availability strategies were implemented: Survivable Remote Site Telephony, Automated Alternate Routing, etc.

Unified Communications Deployment - Multi and Single-Site

Cisco Unified Mobility Advantage is the server in the enterprise that Cisco Unified Mobile Communicator clients connect to, via a proxy server. Cisco Unified Mobility Advantage is deployed behind the enterprise firewall and serves as the integration point for all enterprise services: Dial Via Office, Presence, Voicemail, Active Directory and Exchange integration, Caller ID features, etc.

Ciscopro jumped right onto our project and had it resolved in well less than an hour. Got it right first time and made sure everything tested out OK. Couldn't have asked for a better result.
