Does anyone know of a way to reject chat/messaging for sofia? Specifically the MESSAGE method?

We use FreeSWITCH purely as an SBC/media proxy for voice only, so therefore have no need for directory/chatplan/etc. We have noticed with our current configuration, when our PBX passes a MESSAGE (usually generated on accident...) to freeswitch it sends the MESSAGE right back to the PBX - which creates a loop and jams up the proxies.

The log is complaining as such:

where XXXXXXXXXXX is the destination number for the message.

We do not load mod_sms, and all of the chatplans are disabled.

Thanks.
