I have a list of about 10 articles that need to be created. Topics include: Can I use VoIP if I have a TDM or key system PBX? ... and ... Can VoIP be converted to a digital trunk? This isn't your standard cookie cutter pros / cons type of content. You'll need some knowledge on VoIP technology. If you think you can write well structured articles, then please drop me a PM for more information.
