Last week, we talked getting assurance about service availability and documented uptime. This week, we’re focusing on the importance of preparing your hosted VoIP network to support a variety of media.
 
When planning for the needs of your network, you should first determine the number of users that will need to access it, how you want to be able to interact with each other internally, and how you want to communicate with other outside audiences, such as your customers. There are certain protocols, called codecs, which are tied to the amount of bandwidth you use on different devices, as well as the quality of the call itself. As such, the variety of codecs used in a network directly impact the amount of bandwidth required to sustain a clean, crisp voice call.
 
Firewall Requirements
A regular onslaught of new hardware and applications being added to the network means it needs to be more flexible. It’s important to do your research by looking at the logs and the types of security protocols you want for your firewall. Applications that are running with voice, video, IM and presence, for example, need to have open ports on the firewall. This is why, when looking for a Hosted VoIP vendor, it’s important to have one that brings the equipment on site, installs it, and runs a demo pilot. This is key to how we operate at iCore, which means our customers are assured that their firewall is configured to block the ports it needs to, is open for other services, and can reach our data center to get the proper information needed to run properly.
 
Other considerations include what services are managed vs. unmanaged, since quality of service internally vs. externally needs to be able to optimize your business’ use of resources such as equipment installed and money spent on the WAN.
 
Quality of Service – An Ongoing Priority
Another key factor when selecting a Hosted VoIP vendor for your network needs is the quality of service. This includes factors like response time, signal to noise ratio, cross talk, echo, interrupts, frequency noise, loudness and more. Different types of media require different levels of density, and each individual company has its own standards for success.
 
For some customers, this is irrelevant, given they’re solely focused on features like IM, presence and phone calls. But for others in the mid- to enterprise-level, they need to take into account several things:
 

  • The equipment being used.
  • Which devices are terminating on that equipment.
  • How that device is connecting to the edge of the network.
  • Making sure trunk ports are set up properly with VLANs.
  • Ensuring the data is sent through the firewall for all voice, and that the video traffic is totally bypassing the firewall.

 
Don’t Forget the Conference Room
Another area where many types of media reside, but companies often forget about when it comes to analyzing their network needs, is the conference room. Making sure the right equipment is in place – IP phones, dropdown mics, VTC options, and more – means they also need to be properly tied in so they can be segmented on the network and prioritized over another circuit if in fact they need the ability to connect to other offices.
 
At the end of the day, most customers have both a point-to-point and a broadband circuit, but in some cases customers put voice over managed network and video over broadband – especially if video is a nice to have, but not a must have. Video over broadband ensures the bigger video packets don’t interfere with – or interrupt – voice.
 
For these reasons and more, when transitioning your network and Hosted VoIP options, the media your company uses on a day-to-day basis really plays a big role.
