Audio Issue PBX Express on OVH

[interactive9]

Hi Everyone,

Having trouble with an instance deployed using the PBX Express tool on OVH hosting.

Product	Professional Annual
Version Number	16.0.676

Basically WEBRTC calls have no audio due to issue with ports 10600 to 10999 identified using the firewall checker.

I have many machines on OVH, all were rolled out using the PBX Express tool but I am only having trouble with this particular one.

I have adjusted the security group settings in open stack.

OVH support confirm the ports are open for the instance in question.

Any ideas? I guess I should be looking at the configuration of the instance itself but as I say, it was deployed using PBX express and my linux knowledge is limited.

Thanks in advance.

is this instance on OVH an old one? perhaps port range at install time was smaller than what it is used now?
for sure it sounds something is wrong, if OVH support said ports 10600 to 10999 are open and 3CX firewall checker say they aren't.

As you have audio issue, I guess then most probably RTP ports firewall checker indicates are not really open.

I would start on this, having ports seen open or perhaps do a backup and reinstall a fresh instance with actual PBX Express restoring during install

Thanks for the response.

Not that old, deployed on 09/07/19, I have instances deployed on OVH before and after this one which are fine.

I'm sure the backup/restore process will fix the issue, it just seems to be a bit of work involved for what may be a simple fix for someone who knows linux.

Hi,

What you can try:

• Restart all services and run firewall checker
• Check if iptables directory exist (/etc/iptables) and if so check if rules.v4/.v6 file contain the proper ports.
• Check in 3CX the parameters “WEBRTC_WRTC_FIRST_PORT” is on 10500 and “…_LAST_PORT” is on 10999.
