I have tried setting up the GXW4501 as close to how I have a Vega 100g setup.
Telco PRI comes into my building. Connects to gateway via T1 port.
Gateway connects to my FreePBX as a registered SIP trunk via LAN/WAN port.
On the Vega, it works - the gateway registers as a SIP connection with username/password.
On the GXW4501, it shows as ‘anonymous’ registration in the FreePBX/Asterisk logs.
I was hoping someone who uses the GXW4501 in a similar situation could share their setup.
