External User using Bridge Setting to dial out.

[paul.obrien]

Hi All

We have a customer with two sites - they are linked using the Bridge feature in 3CX.

The main site is the master - the secondary site is the slave.

It has become apparent over the last 2 days that someone is authenticating to the secondary site phone system using the Bridge details - i.e. 10001.

They are then able to dial out over the ISDN lines. It seems to relate to the fact that there is no authetication required for the secondary site Bridge connection as it is dialling out - can this be secured in any way please?

Thanks

Paul

Could you not enable the Tunnel option for the bridge? Perhaps in the meantime,perhaps, change the bridge "number", at both ends, to something less likely to be guessed.
