    I'm using an AVM FritzBox 3790 as an ATA so I can use a cordless phone as na extension of the 3CX PBX.

    We have about 50 Cisco SPA504G's and a few other cordless phones connned using a combination of PAPT2's and a Billion 7404 VNPX. All connect and work without issue.

    In the last week I have been experimenting with FritzBoz as it has an ISDN (Basic Rate (BRI)) FXO along with two PSTN FXO's.

    While I can get them to connect to 3CX and work without issue. Every 10 minutes or so I get the following in the 3CX activity log

    Despite this message, the extensions remain registered and oprative. We don't have any license limt issues.

    Any ideas would be great.
