VoIP News

Thought it was time for another VoIP update.
I'm still using Sipgate who I have now been with for quite sometime since I ditched Gossiptel who I haven't missed one bit but at least they did eventually credit me with the money they owed me.

Just over a week ago I asked Sipgate about why I couldn't dial 0870 and 0800 numbers and they informed me within 30mins (excellent service) that is should be working within a couple of weeks.

Obviously this week I've had need to call my car insurer and stuff which were undoubtedly on 0870/0800 numbers. I hoped for the best and dialled...all connected no problem. No charge for the 0800 number and "UK NATIONAL (7,51 p/min)" which is pretty reasonable considering all the other costs and zero line rental. To dial a freefone number with no charge whatsoever is pretty competitive to say the least.

Basically, so far so good with Sipgate.

My only issue, which is a VoIP not a Sipgate issue, is with the bandwidth requirement. I have a 1500/256 downstream/upstream service with NTL which is great for internet usage and handles VoIP pretty well but for one thing. I have a web/mail server hosted here and when it gets busy (users picking up email etc.) I find it can crack up the phoneline a bit, mainly on the remote end, and sometimes it will disconnect completely. I currently have my Sipura adapter set to the highest quality/bandwidth so I could maybe adjust this to improve it in this situation but just thought I'd make you aware of this if you're planning to host VoIP and another server on the same line.

I am aware there are broadband routers out there who run Quality of Service algorithyms to protect VoIP and these may well be worth an investment. As I understand it, Vonage may supply routers of this kind as standard but they won't allow me to use my own VoIP adapter.
