🎵 Step 4 — Configure Codec Priority
Set the audio codec preferences for optimal call quality.
VoIP → SIP Trunk → Codec Settings
G.711 u-law is the recommended codec for Jamaica. G.729 uses less bandwidth but requires a license on most NEC systems.
📤 Step 5 — Configure Route Table
Set up outbound call routing through the WOCOM SIP trunk.
Routing → Route Table
Configure dial patterns to route outbound calls via the WOCOM SIP trunk.
If your system uses an ARS (Automatic Route Selection) prefix such as 9, configure digit modification to strip the leading digit before sending to WOCOM.
📥 Step 6 — Configure DID / DISA Routing
Route incoming WOCOM calls to extensions or groups.
DID → DID Table
Map incoming DID numbers from WOCOM to internal destinations.

The NEC SL2100 requires the VoIP Daughter Board (BE116500) for SIP trunk support. The SV9100 requires the GCD-CP10 VoIP resource blade. Ensure hardware is installed before configuring.
Congratulations! Your NEC system is now connected to WOCOM Flexible SIP Trunk. Place a test call to verify both inbound and outbound functionality.
