I have an 8 session SIP trunk that comes in from our local provider connected to a FreePBX box which serves about 15 phones locally. We have no plans of ever having any phones not directly connected to our LAN. The connection for the SIP trunk is dedicated and connects directly to the providers demarcation box. Is there any reason to have a SBC in this scenario? If I do not use a SBC what risk (if any) am I leaving myself open to?
Thanks in advance!
