Hi I am planning to try to use Asterisk for testing purpose , for PBX systems , I have one PC with RHEL 4 I want to buy ?digium? cards for this purpose , but I am not sure about which card to buy , this field is totally new to me , requesting guidance for selecting the card I am in middle-east , UAE , Dubai . where the OpenSource / Linux usage is very less . I would also like to know from the members that whether any one in this area is using Asterisk Thanks Joseph John ___________________________________________________________ How much free photo storage do you get?
