Hello everybody, I have booked fights, hotel and tickets for the Rome VON meeting!! I hope most of you will be there! I have a little problem... My OpenSER server has the IP 88.191.45.91 My SIP/PSTN gateway has the IP 212.129.6.65 I do not require authentication to send INVITE from my openser IP. How is it possible to change the To: <sip:0677832974@sd-7501.dedibox.fr:5060;user=phone>. to To: <sip:0677832974@212.129.6.65:5060;user=phone>. ?? Thanks!!
