[Asterisk-Users] Concurrent Call in Asterisk

[Stephen]

Hi All,

Is it possible to have only one SIP account that is shared by several 
users ? I am currently setting up one asterisk box for a small company 
(around 7 users). Can all of them make simultaneous call using only one 
SIP account for termination or I have to setup individual account for 
all of them (which will be very troublesome on my side as I have to keep 
reminding them to top up , would be good if I just manage one account) ?

Thanks in advance.
Stephen
