asterisk users - Mar 2005 - Incoming response and external access

I'm all up for reading and looking round for people in the same boat
to try and solve the issue together, but there appears to not be large
community yet, just the asterisk mail lists.

I got Asterisk working with X-Lite great now for internal calls and
also calling land line numbers etc. The two problems i'm currently
having are:

1. When someone calls in the phones ring 3 times then Asterisk kicks
in, there is about a 3 second gap before Asterisk starts to ring the
default group. Can this be cut down ring straight away?

2. I cannot seem to get access to Asterisk box from the net. I setup
TCP/5060 and UDP/5060 to forward to my Asterisk IP in IPCop, but I
cannot even get in on port 5060 on the LAN, I have checked the
settings in sip.conf and appear to be okay.

Any ideas?

Thanks

Actually, the asterisk community is very large IMHO... There are the
various mailing lists, IRC, the wiki, the asterisk documentation
project, and many other websites/forums/wiki's/etc which have relevant
community members....

This is the very old, very standard problem... disable callerid on the
incoming line/port, and it will work as you expect. With analog ports,
you need a couple of rings to receive/process the callerid.

Asterisk only uses UDP, and AFAIK, you also need UDP ports 10000 to
xxxxxx see /etc/asterisk/sip.conf for details.

You will also need to set the various NAT related config options in the
sip.cfg file.

As far as getting it to work on your LAN, well, I though you said you
had X-Lite working for internal calls, which implies it is working on
the LAN at least ???

More details if you need more help. Also, please see the
www.voip-info.org wiki first.
