Thanks Ariel !

Subject: [Asterisk-Users] Registrar only setup

 

Hello,

 

I'm having trouble figuring out how to setup Asterisk so that it's only a
registrar - not passing any RTP data during phone calls.

So far I got this far:

 

Asterisk server holds registration information for phones

Phones register with Asterisk giving it their ip+port where they can be
currently contacted

NAT doesn't seem to be a problem because STUN seems to take care of it
nicely for me.

 

The hard part that I don't understand is this:

 

Phones can call each other BUT all the RTP traffic is passed through
Asterisk . I don't want this, I need that the phones call each other
directly based on the registration info stored in Asterisk.  I'm having hard
time wrapping my head around this - I think I'm missing some key part - but
the way I understand Asterisk is that it listens for requests on the SIP
channel, when it gets a request it handles it appropriately using it's dial
plan.  But in the dial plan the only thing that makes sense to use is "dial"
and once I do that all the RTP is sent through asterisk (in-out) to the
other phone. right?

 

Or maybe the problem is on the phone setup?  I tried to make sure that I'm
not specifying any outbound proxy but I do have to specify "proxy" otherwise
it will not know where to register . right?  

 

Or maybe I'm all messed up 8-P . I thought I understood asterisk at least a
*bit* until I came across this :-)

 

Thanks for any clarification,

Tomas
