VoIP not working over your broadband connection? We may have the explanation.

By: Trefor Davies | Monday, 19 May, 2014

VoIP over broadband not working? It may be the router. Routers provided by some major ISPs are preventing their customers from using VOIP services such as Skype.

The routers themselves include functionality or elements of...

By: Marcos Campos | Monday, 12 May, 2014

Vastly Objectionable Ignominious Phrase

What the lone acronym in “VoIP Week” does NOT represent.

I have been involved with the VoIP scene since 1999 when my employer at the time, Mitel, decided it would “get into VoIP”. In those days the discussion was very much whether SIP or MGCP would win out. Each platform vendor had its own version of MGCP so the bet was placed on SIP. At Mitel I developed one...
