Hi,I have a broadband UL 900 PLUS connection. Though the doubts what I'm going to ask were discussed in the forum, I need a bit more detailed reply on all those matters.1. How can I call a telephone from my computer. What do I need to do so? Which services offer such facility? What will be the cost of these?2. How can I connect to more than one computer with a BB connection. What are the equipments needed? How to connect these? 3. What is the difference in connecting a modem through an USB port and LAN port? I had initially connected it through LAN, but now I am using it through USB cable. Is there any difference as far as speed is concerned, or in any other aspects in between the two connections? Which one do majority of you prefer?Hope I will get good responses for the queries from you experienced guys.Thanks in advance.Asha Menon
