[asterisk-users] Asterisk without PSTN interface cards

Alejandro,

   I am not sure if the debian release yet contains 1.4.x.  It may be safer 
to compile from source if you want the bleeding-edge version.  But 1.2.x
works quite well, too, so it's really up to you.  I prefer 1.4.x personally
at this point, now that it's been hanging out there for a while.

> 2) Do I have to configure a dummy PSTN interface in my case ??

   I am not sure exactly what you mean by dummy PSTN interface, but in 
principle, the answer is no.  However, there are situations in which it
may benefit you to have a Digium-derived card in the machine so that the
RTC (real-time clock) on it can be used for driving the intervals of
hold music, conference calling (MeetMe), etc.  But there is also a 
"ztdummy" module that can be loaded into the kernel which emulates such
an RTC.

   So, if your intent is purely to use SIP internally, no need for any PSTN.
