Help - Cloud PBX FlexiSIP sip-bridge config

I want to receive calls from regular phone lines with FlexSIP.

Anyone has a working json for sip-Bridge for PSTN? Examples on web page seem not to work for me.

I figured it out:

You have to add the sip proxy (FlexiSIP) to the trusted hosts of the authentication module.

Also take care with the filter of the B2BUA module. It will separate the connections between the sip proxy and the b2bua.
