 |
|
Hi all,
I'm testing some call scenarios with my asterisk server. I've two
questions to make sure my understanding of SIP is correct:
1) What does the localnet setting in sip.conf actually effect?
Does it mean that inbound SIP calls, from outside the LAN get treated
differently from those on the LAN? Is it just a NATing thing??
2) The really basic one: If I wanted to make a really simple SIP
to SIP call, eg Xlite to Zoiper client to client, would the URI be :
sip:2001 at 192.168.0.1 on Zoiper?
I'm trying to make calls to sip: ext at serverip, but I'm not sure if the
format should be:
ext at serverip or
sip:ext at serverip or
sip://ext_to at serverip/ext_from
etc,
At the moment inbound SIP calls work, and I'm trying to understand *how*
its working..
Thanks,
Adrian

The localnet flag tells Asterisk about the private subnet that it is
sitting in. This allows Asterisk to use its own private IP address (as
opposed to NAT's external IP) when communicating with entities that
are also behind the same NAT.

Normally when both your devices are registered with Asterisk, you
would simply dial the extension number (e.g. 2001) with no SIP-URI
syntax.

You should need to dial the extension number only. You typically enter
a SIP-URI (sip:user at host) in your SIP phone when you want to make a
direct call to a SIP entity that is not registered with your local SIP
Registrar.
