NO AUDIO on Fanvil X5U IP Phone

[Mayur Patel]

HI

we have configured 3Cx on premise NX 32 Lite device.
FANVIL X5U IP Phone and NX 32 are into same network.

I can make/receive call to/from IP phones but NO AUDIO at all. If i use same exn as mob apps works fine.
we have checked PBX AUDIO ticked, via STUN/LOCAL LAN etc. It registered correctly as well.

ANY HINT ? We don't have any firewall.

The phones are running as the correct firmware https://www.3cx.com/sip-phones/fanvil-x3-x5/

The phones are provisioned as local lan, and not stun ? Being local you need to select local lan - I would reset the phones if you have used stun

If you remove the phones settings within 3cx, and factory default the phones does it appear in bold and you are able to assign it to an extension - step 3 in above link

When done as @Saqqara describes, you can then make a call to *777 Echo service and see if you can hear your own echo as a test.

HI, I get a similar problem no audio both way on X3SG behind SBC, phone is ringing but no audio at all.



I did a successful echo test *777, after I did a phone reboot from console and this seems to restore phone working fine with audio both ways.
