SV8100 Remote Ext without VPN <Analog IP Phone_ITX series>

[Onne]

My System:
- SV8100 with trial licence.
- NEC Digital IP Phone DT700 series
- NEC Analog IP Phone ITX series
- 2 static internet connection

IP phone-->modem-->(internet)<--modem<--SV8100

I want to try setup for remote extension without VPN.
Its working well with DT700, using NAPT setting in PABX and NAT port forwarding at each modem.

I'm already registered for IP extension.
But I still got some problem using ITX series.
"No Service"

Please help...

I think you are using FXS gateway for analog phones.
8100 is supporting sip extensions over nat with latest software . V9.5

I'm pretty sure that the NAPT Licence only works with the DT series of handsets as the handsets web server handles part of the NAT traversal. You also require port forwarding to be setup on the site where the PBX lies to tell the traffic to go to the IP address of the CCU. Have you set this up yet?
