I've been reading this forum for over the past 4 years and have gained a<br>
wealth of knowledge. - Thanks to all!<br>
<br>
I don't post very often but I've just ran into a problem/condition that I<br>
simply can't figure out. - Hopefully some kind soul will help me.<br>
<br>
I've got an Asterisk server in a lab environment on my home LAN. - The LAN<br>
is "talking" to the Internet via a Linksys WRTG-54 router connected to my<br>
cable-modem. - On the home LAN, I've also got a couple of Cisco phones<br>
(7940's) and they work fine talking back and forth with each other via<br>
Asterisk.<br>
<br>
In fact, I've also got a Broadvoice account with a 7960 logged in all the<br>
time and it works fine. So I know SIP works through my router.<br>
<br>
On the router, I've turned on "DMZ" to point to my Asterisk box's static IP<br>
address.<br>
<br>
My home (real world) IP address is static.<br>
<br>
The Problem: When I grab one of my Cisco 7940's and take it to my office,<br>
it does not "see" or "register" with my home Asterisk server after I change<br>
it's proxy to point to my home IP address.<br>
<br>
Any Ideas? - Is this a router issue (sure seems like it)? - Much thanks in<br>
advance.<br>

</blockquote><div> </div></div>I suggest using port forwarding instead of DMZ. I have seen this issue before, where DMZ would not work. It is also more secure to just open the required ports.<br><br>Some more thoughts. Set externip in sip.conf. Set all phones to nat=yes, "it just works" whether the phone is NATed or not (and is more secure).<br>
<br>Get on the Asterisk CLI and turn of sip debugging and post some output if you are still having problems.<br clear="all"><br>-- <br>Thanks,<br>Steve Totaro <br>+18887771888 (Toll Free)<br>+12409381212 (Cell)<br><br>
