<p class=MsoNormal><span lang=EN-US><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span lang=EN-US>I have a CUCM 7 server configured in a lab at
work place that works fine with SIP phones (Cisco Ip Phones, Linksys &amp;
X-Lite). Now what I want to achieve is register a SIP phone at home with the
CallManager at work and call the internal numbers. I have some spare public IP&#8217;s
from the ISP and have a Cisco 1800 router connected to the 2M SDSL line. Please
can you let me know if this can be achieved, has anyone for a sample router
config to allow SIP from outside and map external IP to an internal IP.<o:p></o:p></span></p>
