SL1100 Trunks

[Glenn2]

I have a SL1100

I connect with my VSP via a couple of Grandstream ATAs through the analogue trunk ports of the SL1100.
I don't have a SIP Trunk, 4 separate SIP accounts, mainly because the VSP gives good pricing on unlimited call plans with this configuration. They won't do unlimited calls through SIP Trunk configuration.

When I look to configure the SL1100 direct with the VSP, NEC manual says I need to have a trunk with a minimum of 4

I have license for feature 5001 System Port License IP Trunk quantity of 4.

It is possible to ditch the ATAs and use the SL1100 only with this VSP?

You will need a VoIP daughter board, and someone who can assist with figuring out the SIP TK settings. As well as some router settings. VSP was not vetted by NEC, so there is no document to help. It's up to you to figure it out. Get as much info as you can from VSP as to how they want it set up. Maybe some folks here can help you out.
