Introduction

These application notes are provided for dealers who are configuring AltiGen Communication’s MAXCS with Level3’s SIP-Trunking service. From an administrator’s point of view, a SIP trunk is very similar to a Triton analog trunk. Once it is up and running, you can assign a trunk access code to it. You can also mix SIP trunks with analog trunks, T1, or PRI trunks in the Out Call Routing table. Like analog trunks, each SIP trunk has a PSTN number. SIP trunks can also receive caller name and caller ID.

Verify Configuration

At this point, you should verify the configuration and make sure that the voice path can be heard in both directions.

1. Make a call through the SIP trunk.
2. Receive a call through the SIP trunk (for convenience, call from your cell phone).
3. If you have several SIP trunks, make/receive several calls at the same time.

If the voice is not heard in both directions, please review the configuration steps to make sure you have configured the trunks properly. If you still have a problem, contact AltiGen Communications.
