Is your data network ready for VoIP?

Hi folks! One of the greatest things about today’s network is that it seems to be able to handle anything. It doesn’t seem to matter what you want to do on your network, there is always a technology around the corner that can make it happen for you.

Well one of the most common things happening today is the conversion of data networks to voice and data networks. With the coming of VoIP, network engineers have been put under an increasing burden to support the world of the telephone when historically data and voice have been two separate entities.

There are a lot of people that erroneously think that VoIP is all about the phones and the PBX, but in reality if you don’t have a data network that can handle the traffic, none of that is really going to matter. Some of things network administrators find out in the end is that a switch isn’t always just a switch. What I mean by this is that administrators have been forced to cut and slash budgets and buy cheaper equipment only to find out that their switch is sub-par and cannot support a voice network. They are then faced with redoing their entire data network infrastructure which makes the cost of going to VoIP prohibitively expensive.

If administrators really look at what is offered to them when they buy network equipment such as switches, they can then plan for future VoIP deployments so when the time comes their data network will be ready. Things such as QOS and POE are two items that are not paid heed to when buying switches if VoIP isn’t in the equation, but then you find out you need it when the company starts going in the VoIP direction.

What I’m trying to say here is that in the future, almost all of us will be using VoIP, so you might as well start planning for getting your data networks ready now.

UMA and the BlackBerry 8900 Javelin

Hi guys! As you know I am an avid user of the BlackBerry 8900. I love my BlackBerry for all things personal and corporate. One of my favourite features is UMA. The ability to do phone conversations over normal wireless access points.

However lately I have run into an issue. Sometimes I want my BlackBerry to use the wireless for data, but I want my normal cell network to be used for voice. Unfortunately it seems like the only way I can do this is by turning off the wireless network in my BlackBerry which disables it for both data and voice.

My question is this to all you BlackBerry users out there. Is there anyway to turn off wireless access point use just for voice, but to keep it working for data? If so, please post a comment here and let us know how you accomplished this. I’ve heard some rumours that this can be accomplished by manipulating the service books but unfortunately I do not know the details. Thanks for any help you can provide!
