I’ve not verified this for certain but I’ll make some commentary with respect to the SIP & NAT module
- It seems like ZS 2.0 RC2 has the sip nat module enabled because I saw it on the list when I ran lsmod
- That I need to track udp for the sip ports (5060:5090/udp) with, at least, related and established and probably new
Unfortunately, I’ve not been able to get to the phones and test my hypothesis as I’m snowed-in here in the US North East 🙂
By the way, this is Polycom RingCentral VOIP over Cox’s cable network
