<div class="gmail_quote"><div>Hi Bogdan,<br><br>Thanks for reply. As your suggestion, I configure OpenSips using nathelper module but unable to resolve it. Like when I dial to another DN i.e. 2000 -> 2001, DN 2000 softphone sends try message after that I get timeout error. Even I checked the sample configuration over web pages, but no luck. The link where I visited are listed below;<br>

Hi Ahmed,<br>
<br>
If you have the devices behind NAT and the server is public IP space,<br>
you need a NAT traversal solution for SIP . Either Near-End NAT<br>
traversal (via STUN) or via Far-Ed NAT traversal (in the opensips script).<br>
<br>
Regards,<br>
