PBX Express firewall changes

[Anthony.AUS]

Hi all --

Disclaimer, I am very new to 3cx and the intricacies of VoIP.

I have a instance of 3CX PBX Express (via the web wizard etc) and I have subscribed to an "approved SIP provider" for 1 SIP trunk.

We are suffering from repeated and random SIP deregistration and registration. The SIP provider has advised that:

1) The SIP re-registration time out was to low at 60 seconds and to change to between 180-240 seconds (this is done)
2) To edit advise the firewall provider to allow outbound SIP to 2 public ranges.

I have completed #1 easily but #2 i have no idea how i can do this on a PBX Express instance?

I cant find documentation about the 3CX PBX Express instance specifically which addresses how i managed the instance opposed to the PBX.

Another thing is that the IP is dynamic in the PBX Express (highlighted red) which I would like to change (i think thats best - right?) yet i cannot see /have access to change this detail?

Can anyone please shed some light.

Many thanks
Anthony

Hello @Anthony.AUS

Did you use the 3CX free one year hosting account or did you install the PBX on your own account?

Hi yiannisH I used the free one year hosting.

Thank you

Hi yiannisH I used the free one year hosting.

Since this is hosted by 3CX you do not have access to the OS and the PBX is only available with a Dynamic public IP. To be able to have access to the OS of the instance and a static public IP you will need to host the PBX to an instance of your own.
