I use a dual port SPA112 ATA, which according to its datasheet supports secure RTP. I would like to connect it to an IPBX which supports secure RTP.
I have installed the latest firmware for this ATA (1.3.5 (004_XU001) Sep 16 2014)
I have done a reset factory after the firmware upgrade.
The serial number is: CCQ18130310
According to the documentation, there are two places in the ATA web configuration to configure the use of secure RTP, one in the Voice / Line1 or Line2 menu, the other in the Voice / User1 or User2 menu.
However, when going to these menus, the secure RTP options are just not there.
So my question is: could it be that secure RTP is disabled in some countries? Or is there another problem ?
