Registration (default)
Your softswitch registers to sip.non-cli.site with username + password. Works from any IP. Re-registers every 60s.
Pros: zero config on our side, works behind NAT, easy to move servers. Cons: registration churn under load, password is a credential to protect.
IP whitelist
You give us 1–4 static public IPs. We accept INVITEs from those IPs with no authentication. No registration needed.
Pros: lower setup latency, no password to leak, cleaner SIP traces, marginally better failover. Cons: locked to specific IPs, no good if your softswitch IP changes often.
How to request IP auth
Open a ticket with:
- Trunk username
- Static IPs to whitelist
- Whether to keep registration as a fallback (yes/no)
We provision within minutes during EU/US business hours.
Hybrid
You can have both — registration as primary, IP whitelist as fallback. Useful during server migrations.
