Step 10: Configure the SIP Trunks
Next, you need to configure SIP trunk channels. Before you start, note the following:
• An AltiGen SIP Trunking channel is licensed. You need to buy and register a license to be able to
configure this option.
• AltiGen does not guarantee the voice quality of the SIP dial tone coming from your service provider.
You need to work with your data service and SIP trunking service provider to make sure adequate QoS
is provisioned for your WAN service.
• AltiGen does not guarantee SIP trunk implementation will work with all SIP dial tone service providers.
AltiGen dealers are notified of AltiGen-tested and certified SIP-Trunk service providers. Configuration
guidelines for each AltiGen-certified SIP-Trunk service provider can be found in the AltiGen authorized
Partner Knowledge Base, available from the AltiGen Partner Web Site. SIP dial tone service providers
need to support the following:
o G.711, G.723.1, G.729 codec
o RFC 2833 for DTMF tone delivery
o SIP MD5 authentication with SIP registration
• If MAXCS is behind NAT, verify that your SIP SP can support this configuration.
When subscribing to a SIP dial tone service, typically your service provider will provide you with the information
required in the SIP Trunk Configuration dialog box. Enter the service parameters for each SIP trunk channel
configuration individually.
Note: Make sure you have enough IP resource boards to cover your needs.
To configure a SIP trunk,
1. In MAXCS Administrator, open the Boards panel and double-click SIPSP.
2. Select a SIP trunk type and click the Trunk Properties button.
3. Click the SIP Trunk Configuration button.
