If they actually have SIP devices, SIP is probably turned off as it breaks
many features people want like BLF. This does not hold true for premise

Wouldn’t there be a short window of opportunity like 5 or 10 minutes before the
TCP connection ages out in the NAT connections table? Or does this also rely

I worry more about UPnP which can program permanent port forwards in the

because most firewalls and nat base their packet forwarding on the origin. If

when we establish a connection outside we open an arbitrary source
