Hello,
I have 20 Fanvil X3S phones in my office connected to 3CX iin cloud via STUN. However, they where all provisioned with same SIP port 5065.
This works fine and I did not have any problems so far, however, the tutorial below clearly states that I should either increment ports for each phone (for example 5060, 5061, 5062...... ) and also RTP ports as well or use 3CX SBC.
I have heard on this forum that SBC has many benefits (possible to use same port and additional encryption, as well as masking Voip traffic). However, I also heard that phones become dependent on SBC device, and it needs to reboot and may putt all the phones offline if it goes down.

Am i just lucky that everything works? Should I
1) leave everything as is because "Ain't broke don't fix it" ?
2) Change ports for every phone to use different ports?
3) Switch to SBC and keep same ports?
Thank you
