+# 2026-03-20 Cutover Notes
+
+## Result
+
+The new PBX was cut over successfully to `192.168.1.16`.
+
+Verified after cutover:
+- extension `106` registered from `192.168.1.51:5060`
+- extension `107` registered from `192.168.1.51:5061`
+- internal call `106 -> 107` worked
+- outbound Bandwidth call worked after E.164 route fix
+- inbound DID call worked
+
+## Key fixes during cutover
+
+1. Corrected FreePBX external SIP/media address to `166.70.117.159`.
+2. Removed the temporary `192.168.1.17` service address from the PBX.
+3. Confirmed router NAT already mapped `192.168.1.16 -> 166.70.117.159`.
+4. Updated Bandwidth-facing outbound routes to send `+E.164` numbers.
+
+## Current routing assumptions
+
+- Bandwidth: inbound DID and local Utah outbound
+- binfone: interstate / long-distance via IAX2
+- SPA112 ATA: `106` and `107`, proxy `192.168.1.16`
+
+## Follow-up
+
+- Re-test binfone route with an interstate destination
+- Clean up any stale `192.168.1.17` hostname identity seen in some SIP headers
+- Export or document the final FreePBX configuration state
