<div style="DIRECTION: ltr">all voip protocols embed the L3 address in the signaling protocol. You will need a NAT device that supports a 'fixup' mechanism for those protocols.

<div>I have 2 IP-phones connected to C2621 with the below configuration the problem that, the phones used <a onclick="return top.js.OpenExtLink(window,event,this)" href="http://10.0.0.25/" target="_blank">10.0.0.25</a> and
<a onclick="return top.js.OpenExtLink(window,event,this)" href="http://10.0.0.26/" target="_blank">10.0.0.26</a> and both is NATED on the 2600 router, also both registered in international SIP server but thay can not make calls even between each other, But when i trying to using static NAT (Private--> Real IP) everything working fine but i can not deticate IP for each phone and now the problem due to NAT so anybody could help in that, HOw can i use NAT but in the same time the phones working because it's seems that the NAT port changes it the reason behind the problem
