Issue with VOIP connection - disconnecting calls and not being able to place calls

DamienPepper

Hi All,

We are using a XG125w (SFOS 16.01.1) and are having some random issues with VOIP.

I have checked the DDoS is disabled.  I have also turned off all protection on the firewall outbound rule.

I have tried unloading the SIP module and when I do that they can no longer be heard or hear on the call.

I have put an inbound rule on the firewall for VOIP Audio ports.  When I have re-enabled the SIP module it works and goes abck to the random dropping.

 

In this installation the VOIP coming in is a SIP Trunk.

 

Can anyone share anything that might help with this?

What does the SIP module do?

 

Thanks

DAMIEN
