Aloha,

If we're talking about Rtpengine, it can easily be scaled further by assigning an extra IP address. 

Furthermore, for multi-homed with multiple local network interfaces with different addresses and rtp port ranges, it can run on multiple daemon instances, it can if I recall correctly it supports up to 64.

Howdy,

So you’ve got the reserved ports range 0-1023. Then there’s a few other brackets.

In Linux there are kernel parameters to adjust these ranges, but it has been a few years.

If we’re really at the stage where we are looking at increasing the size of the range, then looking into these parameters is also worth looking into on these rtp boxes.

Typically a box wouldn’t be processing anywhere near the limits to be genuinely worth considering.

But now that RTPEngine has Cuda offloading…
