please see my ngrep report -<br><br>&nbsp;and tell me why my SER cannot send ACK to the pstn gw.<br><br>&nbsp; it is sending to private ip adress with complete wrong adressing like sip:<a href="http://192.168.1.106:5060">192.168.1.106:5060
</a> SIP/2.0.<br><br>i think it has to be like <a href="mailto:sip:phonenumber@192.168.1.106">sip:phonenumber@192.168.1.106</a><br><br><br>
