[Asterisk-Users] Does Asterisk do that?

[Alberto Martínez]

Hello.

I have just arrived to Asterisk. I would like to know if Asterisk can
perform some functionalities I am looking for.

I want to allow voip over sip to some users. All of them must have
their own user name and password to login to Asterisk so only allowed
users can login. All calls started by users have to be redirected to
one account at our voip provider. I think those functionalities can be
covered with Asterisk but I would like to confirm it.

We are interested too in having a real-time control of callings,
knowing which calls are actives, its time and other datas. Is there
anyway to have this information with Asterisk? We are interested y
having it by consulting some files, for example, with a little piece
of software we develop.

We need to be able to finish a call by software, when certains
conditions are accomplished. Can we do that with Asterisk?

Thank you very much for your help.

Regards,
Alberto
