[Aaug] Delayed ring

Well the pros and cons of one implementation over another is for an
Asterisk Beer Meeting *SMILE*.  A lot of the devices have auto sensing
features in them, the sipura apparently doesn't, ok it really doesn't I
was just being nice.

How so?  Is it a requirement of SIP?

Here is the device I'm currently using:
http://www.voip-info.org/wiki-Packet8+DTA310+and+Asterisk
I'm using that device with the original P8 firmware and I pay them for
service.

I can take that device _anywhere_ and get a line out.  I can be double
natted and it still works no problem.  I do not know how it does this
but based on your comments I will assume it is not using SIP?  My
experience with the device is that the only time it failed me was when
the site's firewall was blocking it.  I would then fire up my laptop
convert it to a router and VPN back into our office.  In effect NAT #1
was my laptop and NAT #2 was our firewall at the office.  I've never
even connected to the DTA310 via a web browser to configure any setting.

Possibly this is what someone was talking about earlier about the
difference between IAX2 and SIP.  Something about IAS2 does not have the
NAT issues as SIP.  Is this what I'm experiencing?  If so would
purchasing the Digium IAX2 adapter allow me to use Asterisk in virtually
any environment even if I'm 2x natted or even 3x natted?

That is what I'm testing.  I'm testing the ability to attach the
Sipura-2000 to _any_ network regardless of design and connect.  In most
cases I'll have no clue what that network looks like and if a firewall
blocks me I can tunnel back to our office.  In that case I'm screwed
because I'll be 2x natted and this device will not work unless I
specifically configure it for that configuration.  Each time I move it I
may have to configure it again?

301 is the extension I've configured for the ATA
