 Hello everyone, I’m new to Asterisk and I have a question. There is a
 phone call between two users, then they are talking to each other directly
 or by the server. I mean all packets from the user A to user B will be send
 directly to each other or will those packets from user A must be send to
 server and server will send to user B.

 Thanks.

Both cases can happens. In a VoIP call we have two connections, one is used
for signaling, usually port 5060 for SIP protocol, UDP transport and one is
used for media (voice), usually random port. When the call starts the
asterisk server sits in the middle of the media path, meaning all voice
packets from phone A go to asterisk server and they are rerouted to phone
B. After few milliseconds, if configured this way, asterisk server
instructs the phone A to send the media directly to phone B to save
bandwidth. It is named reinvite

Depending on the technology (IAX or SIP) and the configuration, you can 
choose to have the Asterisk server handle the media (RTP) or not.

[Asterisk-Users] Asterisk question

[Paul Hales]

Any idea how to read an external file, grab some stuff and push it back
into an Asterisk variable?

I can do it the other way with:
system(echo ${UNIQUEID} =  /home/ast/curr_calls) 

but I'm a bit stumped on how to go the other way around

much thanks,

Paul Hales
