I am suggesting a ST500 mobile app for 2-3 employees on a brand new 2100. I have an NEC data sheet on the St500 that says an SBC is needed to connect remotely. Is that true? A simple port forward on the customer router will not accomplish this? If an SBC is needed, any recommendation what to use?

I'm on NTAC reading the ST500 requirements on the SL2100 and SV9100, from licensing, system programming, port forwarding, I'm not seeing what your question is regarding.
Please point me to the document you have.

SBC (session border controller) is required for SIP use at health insurance firms addition to firewalls and is optional for others, a good firewall should be sufficient for you along with programming the system to NTAC specks regarding hacking.
Calling Coral Tech, what are your thoughts?

I've never done an ST500. I just do MLC on the 9100's. SL2100 support is free and if it were me I would call them and verify what is needed. MLC's just require port forwarding or VPN.

Ntac does have a guide and only mentions port forwarding. So I don't know why that sales sheet shows SBC.

HI jsaad
Advantages of SBCs:
1.IP blacklist can be set.
2.Traffic, registration statistics and call records through SBC
3.Check domain names first.(Not a public domain, more like passphrase)
4.SBC can be behind a Router or directly on the public network
This will be the reason why I recommend SBC.
In our country, the IP telephony system is often challenged by customer's IT.

Hi jsaad, have you setup ST500 for your client? if so, is there any feedback?
There are handful of posts on st500 here so its either working flawlessly or nobody is using it.
