asterisk users - Feb 2010 - 1.6.x SIP allow incoming calls based on from ip address?

Hi All,

I read some discussions about the new SIP authentication methods for
1.6.X branches and possible addition of new type of user, type=trunk.
I'm wondering about the disposition about this.  Will it be added?

In 1.2 and 1.4 branch, a SIP invite was first checked for a valid
[user] then a valid host=ip, then if not present send call to
[general]  context=incoming.

In 1.6, a SIP invite checks for valid [user] then TO:
domain=abc.com,context, then if not present [general]
context=incoming.  This is fine and I think I understand the reasoning
behind the new method.  But we have lost the ability to route calls
based on 'from' ip address.

What I'm curious about is if we will be able to configure a sip [user]
type=trunk with host=ip address based on FROM: IP Address and direct
it to a specific context.

sip.conf

[provider_1_trunk]
type=trunk
host=ip address
context=provider_1_incoming

or something like this:

[from ip address]
type=trunk
context=provider_1_incoming
authentication=none

Thanks.

Not to the 1.6 branches, but we hope to have something for 1.8.
This is all based on very old discussions that have matured over the years.

Yes. The host=ip is a peer, so first user, then peer, then to a context
specified in the [general] section or a context named
"default".

No, 1.6.x should work exactly the same as 1.4. The domains are in 1.4 too, and
precedes the [general] section as you say. We still have users and peers.

Something like that, yes. Type=trunk will be replacing some usage of type=peer
today and have both IP and domain based matching of incoming calls.

Hmm, well this is not happening like you say.  I'm currently using
1.6.0 latest release and the 'host=ip address' is not being looked up.
 It works in 1.4 but not in this version.  I'll do some more debugging
and try to figure out what is going on.

Thanks.
