Currently, I am using VoIP service from rogers here in School lab.
I can make calls from my sip and iax soft phone to asterisk server by
some
preconfigured numbers ( like 100,1,2000, etc. ) but I have followign
concerns.
How can I connect my asterisk server to my VoIP service provider
network(VoIP
gateway) to reach to the outside world ?
Do I need to ask to my VoIP service provider for that ? for username and
password because I am not administrator here and being a student I am
not aware
about that. :) I will have to ask to my network administrator. :)
Asterisk can use a SIP account as an incoming and outgoing channel.
I've only personally set it up for incoming, but I would guess it's a
very similar setup for outgoing (at least, that's what the comments in
the file seem to say). The same parameters you are using to connect
your soft-phone to your service provider will allow you to have your
asterisk server connect as a SIP phone to the service. (If you mean you
don't have a SIP username and password, well, you'll have to get them).
See the sip.conf file in the /etc/asterisk directory for information on
how to do it.
Now, encoding a password into the config file is sub-optimal, of course,
but it does work (I believe there may be a way to define the password
elsewhere, but I haven't looked into it). For an academic demo this is
probably sufficient, just be sure to protect the file from prying eyes.
My impression is that using the SIP channel instead of an IAX one is
largely deprecated as a "real world" connection mechanism (IAX being far
preferable), but again, for an academic demo, or in special
circumstances, it does seem to work.
Again, lots of instructions in the sip.conf file. You may also find
that reading "Asterisk the Future of Telephony" (available free,
online)[1] helps you with lots of these "where do I put my finger"
questions. It takes about 6 hours to read cover-to-cover, and gives a
good general background for understanding how asterisk works, what you
can do with it, and where to look to figure out how to do those things.
Quite a reasonable investment in time.
