[asterisk-users] How many outgoing phone line/voip account do I need?

[Kurt Kuo]

Hi list,
I have an application which has to automatically dial and send out a voice 
message to 50 different phone numbers at the same time. Does it mean that I 
need to sign up 50 phone lines or voip accounts in order to achieve this 
purpose? Is there a provider(voip prefer) who offer a special account which 
is able to handle multiple calls simultaneously?
Thanks in advance.

Kurt
