Will we see long term success on the same level as the typical PBX?
VoIP connections can be initiated with anyone, anywhere and anytime there is a data network connection available. VoIP comes not only with many more features than the PSTN but is vastly less costly to use and administer. The diagnostic is clear: VoIP is here to stay and we are here to help you benefit!
By implementing VoIP, you can add some very beneficial features that were previously not possible and lower your telephone administration costs. Still, VoIP comes with some challenges.
In a VoIP environment, one minute of poor voice quality in one-hour conversation may not even be reported by traditional voice network tools since no downtime was detected and any data loss fell into an acceptable range of fault tolerance. However, anyone who has experienced a dropped call or inconsistent service knows that even one minute of bad call quality is unacceptable and does not happen in the legacy phone world.
Additionally, if you link an IP network to your voice/fax/pager system you open yourself up to denial of service attacks and spoofing.
Any network problem interrupts phone service and the environment has become much more complicated for Network Engineers to diagnose problems leading to the one constant in most conversions: the dissatisfaction of the users
Our VoIP Solutions
Our goal here at InterNetworking Link is to alleviate obstacles and risks in your VoIP effort so that you can truly benefit from the lower cost and many features that VoIP brings.
- First consider if there is a better choice than going VoIP
- Offer QoS and QoE Enterprise VoIP systems and hold VoIP vendors accountable
- Fully educate members of the Executive Staff and Properly plan new network infrastructure investment
- Tools for Network Engineers to diagnose problems since any network problem interrupts the phone service and the environment has become much more complicated
- Train people who will be managing the new system so they can have a positive experience
Existing Solutions
- Many enterprise systems like Cisco VoIP systems provide better user experience
- 802.11r standardizes Fast Transitions to allow smooth roaming
- Bandwidth policing and applications maximum limit allocation. New state-of-the-art algorithms, advanced QoS techniques and features can prevent congestion
- End-to-end measurement and QoS(802.11e) management, not just probbing for # of dropped packets
- Wi-Fi Multimedia or WMM is a certification using a subset of the 802.11e draft standard to provide QoS features for VoIP or multimedia streaming devices.
- Call assessment through measurement of QoE at the application level between users
Common Objections
- Mixed feelings from experience at home with VoIP on the internet
- Roaming requires fast handoff to avoid interruptions
- Network downtime due to bandwidth drain in an environment with multiple types of traffic. Fear no consistent QoS
- Needs new processes, new skills to manage new VoIP challenges. Cannot use traditional networks solutions for real-time resolution and intra-site and site-to-site end-to-end monitoring.
- Fear that jitter, latency and packet loss peculiar to IP protocol could not guarantee quality of experience(QoE) or meet business end-user expectations
