[SR-Users] Setting up MSFT Teams SBC <> SIP trunk but forwarding ACK and CANCEL messages

On latest versions I’m trying the sipdump module, the one benefit I’m
liking over its alternatives is that you can enable/disable dumping to file
via RPC..

So in normal operation you are not dumping all tls traffic, and then you
can enable it only when you need to troubleshoot something..

Just throwing this out there in case it’s useful :)

Cheers,
Joel.
